May 2023: Work by Dragonfly Data Science featured on TVNZ's 1News on Sunday 28 May.

"A new mapping tool that combines satellite data with demographic and infrastructure information has been launched in New Zealand.

"The tool, created by Dragonfly Data Science, could help with the response to future natural disasters.

"The map uses satellite imagery to show areas affected by flooding, slips and silt, and pairs it with detailed information about the communities in those areas.

"It provides information about schools, hospitals, supermarkets, farmlands and roads affected by disasters.

"Sadhvi Selvaraj, a data scientist at Dragonfly, told 1News that the tool provides timely and relevant information for decision-makers to support response and recovery in an equitable way."

Dr Sadhvi Selvaraj was interviewed on TVNZ 1News.

May 2023: Verum Group’s National Laboratory has something new and glowing. Mike Young, Verum Group’s National Laboratory Manager, has recently overseen the installation of a LECO 828 Series Combustion Analyser for detecting carbon, hydrogen, and nitrogen, with an S832 add-on for independent sulfur determination.

Mike says the new equipment replaces an old instrument that needed continual maintenance.

“We’ve always produced quality results - Verum is trusted for it, but it’s now a lot easier. I’ve also seen a significant improvement in throughput."

Materials the team can analyse include woodchip, pellets, biochars, coals, mineral samples, soils, sediments, fertilisers, and waste streams such as plastics, rubbers, and oils.

“In the past we have looked at paunch grass, DAF solids, peat, and plant waste from greenhouse growing operations as well as the more normal fuel materials."

May 2023: Cawthron Laboratories, the analytical testing arm of Whakatū Nelson’s Cawthron Institute, has announced it will open a new analytical testing laboratory in Tāmaki Makaurau Auckland in mid-2023.

Cawthron Laboratories offers customers a broad spectrum of food testing and product analysis services.

Located in Māngere, the new facility expands Cawthron Laboratories’ service capacity and supports existing efforts to provide a full spectrum of testing services to customers in any part of the country.

Cawthron Laboratories Manager Paul Parker says this expansion builds on the strong relationships Cawthron already has with customers in the North Island and creates opportunities for new customers by increasing confidence in the accessibility and reliability of their testing services.

“Opening a North Island laboratory is an exciting new chapter for us and one that will help us forge new relationships in the North Island.”

May 2023: Motu's Arthur Grimes appeared on a recent CNBC documentary on the origins of a 2% inflation target. If you're curious about the current economic landscape and want to stay informed, this is a must-watch.

The 2% inflation target is key to the Federal Reserve’s vision for stable prices. But, where exactly did this 2% inflation goal originate? Aotearoa New Zealand. In the late 1980s, the country faced high inflation when one economist proposed, ’Why don’t we just have an inflation target?”

U.S. declared its 2% inflation target in 2012. According to the International Monetary Fund, Canada, Australia, Japan and Israel are among the many economies that include 2% in their inflation rate targets.

In the documentary, some economists argue for changing the target, lower or higher, and predict whether it may change anytime soon.

Inflation, the rising cost of goods and services over time, is a topic that affects us all. It influences our purchasing power, savings, and even investment decisions.

May 2023: The ArchEngBuild Challenge is an intensive 3-day competition for New Zealand tertiary students studying architecture, engineering or construction management.

Now in its tenth year, ArchEngBuild brings together New Zealand’s future industry leaders. Thirty of the country’s best architecture, engineering, and construction management students take part in this intensive 3-day real-life client brief competition held this year in Wellington.

They work together to deliver a concept design in response to a project brief. The project brief addresses issues faced by industry and allows the students to come up with creative and innovative solutions.

The event is being held in late August at the Wellington Faculty of Architecture and Design Innovation / Te Wāhanga Waihanga-Hoahoa, with the winning team receiving a $7,500 prize, awarded at a prize-giving event at the end of the competition.

Final-year students can nominate themselves, or tertiary education providers can nominate students, with submissions closing on 16 June 2023.

May 2023: A Guardian article by Tess McClure examines research by Mātai tracing signs of healing in the brains of a group of former addicts.

"Every few months, Cohen “Coey” Irwin lies on his back and lets the walls close in. Lights move overhead, scanning over the tattoos covering his cheeks. He lies suspended, his head encased by a padded helmet, ears blocked, as his body is shunted into a tunnel. The noise begins: a rhythmic crashing, loud as a jackhammer. For the next hour, an enormous magnet will produce finely detailed images of Irwin’s brain. Irwin has spent much of his adult life addicted to smoking methamphetamine – or P, as the drug is known in New Zealand.

"He knows its effects intimately: the euphoria, the paranoia, the explosive violence, the energy, the tics that run through his neck and lips."

May 2023: In the May issue of Canterbury Farming Newspaper, Aqualinc's Director Dr John Bright explains "it's time to talk about water storage development."

The variability of water supply from week to week, month to month, and year to year means that many parts of New Zealand have a mismatch between supply and demand in most summer months.

For most parts of Canterbury this hasn't been an issue for the past two irrigation seasons, but we know well from past dought years that it will be a challenge we will face in the future. Climate change projections show the challenge becoming even greater due to increasing water demand, lower river flows in summer months, and increasing month-to-month variability.

Strategic water studies over the past 20 years consistently show that water storage is a key strategy to address this water supply reliability problem. Improvements in irrigation efficiency, alone, will not solve it.

Dr Bright writes that water storage of the capacity required is not without controversy. Lake Wanaka. Photo: Eyrie Photography.

May 2023: Dr Bibek Yumnam is a Senior Research Officer working in Professor Graham Le Gros’ lab investigating the interplay between parasites and our immune system. He uses his background in conservation of endangered species to offer unique insights into parasites and what they represent to our global ecosystem and health.

The basis of Malaghan's hookworm therapy programme is the concept that having hookworms in our body may dampen down overactive immune responses typical of allergic and inflammatory diseases. Specifically, Bibek is working on the Malaghan’s hookworm clinical study to develop the methodology to produce therapeutic hookworms in a safe and standardised way.

“To really understand why we are doing this research we have to look into the life cycle of hookworms in the natural, pre-industrialised world,” says Bibek. “Their life cycle is inextricably intertwined with us humans.”

"Our bodies are an ecosystem and until recently, parasites have always been a part of this ecosystem," says Dr Bibek Yumnam. Image: Malaghan.

May 2023: Dragonfly Data Science's work with the Social Wellbeing Agency produced an interactive map of cyclone impacts overlaid with infrastructure and demographic data.

The map demonstrates the crucial role that data has played in identifying the land and community characteristics of areas impacted by adverse weather in early 2023. It’s the first time these two approaches have been combined for New Zealand. The map is also supporting planning for the response and recovery.

Aphra Green, Deputy Chief Executive, Policy, Data and Insights of the Social Wellbeing Agency (SWA) Toi Hau Tāngata says the agency had built a demographic explorer with community information, but being able to combine this with geospatial data was a big advantage.

May 2023: New Zealand has 26,559 hectares of Sauvignon Blanc vines, and the way grapes are propagated renders the vast majority of these vines genetically the same - potentially any new pest, disease, or environmental change that affects one vine could affect them all.

Bragato Research Institute and its partners, Lincoln University and Plant & Food Research, have begun a seven-year research programme to produce diverse variants of Sauvignon Blanc to help New Zealand’s $2 billion wine industry become more resilient.

This growing season, the programme has produced 6,000 new variants.

“Plants have the natural ability to become more genetically diverse in response to environmental stress, and this knowledge was used to produce a population of vines with unique traits,” says Principal Scientist Dr Darrell Lizamore. “Since this doesn’t involve crossings with other vines, the plants are still Sauvignon Blanc, and the new variants are fully formed at the first generation.”

May 2023: Prostate cancer is the most common cancer for men in Aotearoa and Tairāwhiti has adopted a global best-practice method to perform prostate biopsies.

A prostate biopsy is a procedure to remove samples of suspicious tissue from a man’s prostate. The tissue is then looked at under a microscope to check for cancer.

Through a new clinical partnership between Te Whatu Ora and Mātai Medical Research Institute, since November last year more than 21 Tairāwhiti men have had MRI-guided, transperineal, prostate biopsies under local anaesthesia in an outpatient setting.

Dr Daniel Cornfeld, head of radiology at Te Whatu Ora in Tairāwhiti and Mātai Clinical Lead, said Tairāwhiti was the first site in Australasia to use this specific Koelis Trinity system technology to perform the procedure in an outpatient environment.

“The new technology will provide an equitable service which will uplift prostate outcomes for our local men, especially Māori and men living rurally,” Dr Cornfeld said.

May 2023: What happens to a building and its individual components when subjected to the kinds of extreme stress, impact and vibration that an Aotearoa New Zealand home might face during its lifetime? BRANZ can now answer that and similar questions more efficiently and in greater detail with the opening of a new structures laboratory at its Judgeford campus.

BRANZ’s structural tests assess whether building systems and products are fit for purpose and comply with the Building Code.

The new lab allows BRANZ to build complex structures as large as a 3-storey building and exert forces on it from two different directions simultaneously, as might occur in an earthquake. The bigger space also means more tests can run concurrently. ‘It gives us the flexibility to assess a wide variety of new building materials, systems and products as they are developed,’ says BRANZ Structural Testing Team Leader Simon Faulkner. ‘We have double the load and stroke-bearing capabilities of our previous facility,’ Simon says. ‘It means we can shake buildings harder and faster than ever before.’

May 2023: It’s near impossible to get good data on water use in New Zealand. This raises questions about public accountability, write Motu Research Analyst Thomas Benison and Julia Talbot-Jones (Motu Affiliate) in a recent issue of The Conversation. The article is based on their own experience of collecting data from the local councils for a Motu Research project on urban water pricing use in Aotearoa.

"As New Zealand’s new Prime Minister Chris Hipkins embarks on reprioritising policies to focus on 'bread and butter issues', the details of the contentious Three Waters reforms remain unclear.

"The reforms represent a radical reshaping of water, wastewater and stormwater management, with the aim of building a new integrated system across New Zealand. The legislation passed in December last year, but the PM has promised a 'reset'."

Whatever the final details, a study conducted by Motu highlights the need for improved environmental reporting to help deliver urban water supply security.

April 2023: Aotearoa New Zealand has high-quality but expensive childcare. Access to suitable and affordable childcare is a prerequisite for labour force participation for many mothers. Motu's recent paper uses data from the Growing Up in New Zealand longitudinal study to investigate how the lack of access to childcare affects mothers’ work.

The report, by Thomas Benison and Isabelle Sin, finds that many mothers whose young children are not in childcare (due to a lack of childcare access) report being prevented from working by childcare access issues. However, just over a fifth of mothers whose children are not in care due to access issues do work, and some mothers whose children are in care still report they cannot work due to childcare issues.

By combining information on mothers’ work status and reasons for not working with earnings data for working mothers of young children, the researchers estimate New Zealand mothers with children under age three who are not working only because they can’t access childcare may be foregoing $116 million or more of wages each year.

April 2023: Meet the newest addition to the Verum Group-sponsored Atarau Wildlife Sanctuary. Last Wednesday, Verum Group Director Luc Bohyn took delivery of very precious cargo – a great spotted kiwi/ roroa chick hatched at the Willowbank Wildlife Reserve.

Willowbank Wildlife Kiwi Team Keeper Bethany Brett and Luc gave the provisionally-named Xanthe a final weigh to make sure it had gained weight before carefully crating the chick for its journey across the Southern Alps to join other great spotted kiwi youngsters at Atarau. Kiwi chicks initially lose weight after they hatch as they use up the yolk sac contents over the first week or so before they start eating.

April 2023: A New Zealand cancer immunotherapy biotech has entered a multi-million dollar commercial deal with leading international pharmaceutical company Dr. Reddy’s Laboratories Ltd for an exclusive license to its unique CAR T-cell technology in India.

Wellington Zhaotai Therapies, a joint venture between the Malaghan Institute of Medical Research and Hunan Zhaotai Medical Group, was established in 2017 to take Hunan Zhaotai's novel CAR T-cell technology to the global market. In 2019 after further development at the Malaghan Institute, a phase I safety trial, ENABLE, got underway in New Zealand. Results of the trial are due to be published later in 2023.

Wellington Zhaotai Therapies Executive Director Peter Lai says the agreement is an inflection point for Wellington Zhaotai Therapies and reflects the successful partnership between the two research teams in New Zealand and China.

April 2023: Aqualinc Director Dr John Bright featured on the cover of this month's Irrigation Leader magazine. John was interviewed for the lead article where he discusses Aqualinc's work helping farmers prepare for a future of more stringent regulations and less predictable rainfall, and assisting water infrastructure managers and government agencies to make wise, environmentally sustainable decisions about water use.

"The availability of water depends not just on what’s flowing in a river or aquifer but on the rules that government agencies put in place to regulate access to the water. It’s likely that agriculture will have less access to water in the future than it does now. Further, when we look at the expected effects of climate change, the month-to-month variability will likely increase. Those factors are going to exacerbate the supply and demand imbalance. Clearly, water storage is a key strategy to address that problem."

April 2023: It’s not every day you get to see glowing green cells, but this represents an important milestone in the work of Gillies McIndoe's PhD student Dr Sam Siljee.

Sam’s research focuses on better understanding the biological pathways used within cells when healthy lung tissue changes to cancerous lung tissue. This information will help him identify the potential use of drug repurposing in lung cancer treatments.

To identify the biological pathways cancer uses within cells, he must grow cells in a dish and use a model to mimic cancer-like changes in cells and block the p53 gene (tumour suppressor gene), known as the guardian of the genome (complete set of genetic information).

The model used to mimic cancer-like changes is called lentivirus transduction. In this model, the RNA (Ribonucleic acid) from the lentivirus will transfer into the healthy cell and block p53. The glowing green cells indicate that the model used is successful and usable in his study.

April 2023: A great survey does more than collect valuable insights, it provides survey participants with a survey experience that captures their attention and guides their thinking. We know that maintaining participant engagement leads to better quality data and makes for happier participants, but how do we keep people engaged?

Scarlatti's Research Manager Mel Escott explores surveys and offers three tips for creating an engaging survey. These are "Bring your audience on board"; "Create a two-way conversation"; and "Use thought-provoking question design".

"People are much more engaged in activities that interest and impact them specifically. You want to capture your audience from the beginning and convince them why completing this survey is important. To achieve this, briefly outline what the survey will involve and the direction it will take. This details, at a high level, the narrative. Good design is empathetic."

April 2023: Dr Karaitiana Taiuru from new IRANZ member Taiuru & Associates Ltd has recently blogged a think piece about the potential impact of AI on te ao Māori.

He writes that Māori Data Sovereignty is now more crucial than ever, with Dr Pratik Desai, a Silicon Valley computer scientist who has founded multiple Artificial Intelligence platforms, boldly predicting that a human being’s “consciousness could be uploaded onto digital devices by the end of the year [2023]”.

"There are already reported scams of AI impersonating people’s voices based on as little as 30 seconds of audio. I predict that Māori media personalities and te ao Māori leaders will be targeted en masse to scam our own whānau, marae, hapū, and Iwi."

"Future breaches of tikanga will create new issues for whānau, hapū and Iwi, and for Māori individuals over their own rangatiratanga of their physical body and thoughts after death."

April 2023: A Stuff article on 12 April about the link between environmental factors such as coffee consumption and Parkinson's cites Parkinson's epidemiology numbers and research by the New Zealand Brain Research Institute. The upshot of the article is that numerous studies have found that coffee drinkers develop Parkinson's disease later than those who don’t. Although the institute cautions that one needs to be careful with the correlation between factors such as coffee consumption and Parkinson's: a correlation does not imply causation. This is one of the many factors NZBRI's Parkinson's Environment and Genes Study (PEGS) is investigating.

The PEGS research is investigating the genetic, environmental exposures, and other lifestyle factors associated with Parkinson’s disease, particularly within a New Zealand context. The research will provide a unique insight into local risk factors and possible protective factors and will help further understand the causes of the disease.

April 2023: A new research report from WSP Research, commissioned by Waka Kotahi NZ Transport Agency, has found most owners of one and two-star cars either don’t know or overestimate how safe their vehicle really is.

That's one of the key findings behind a range of recommendations in the report, titled Getting people out of 1- and 2-star cars. Waka Kotahi is using the recommendations to inform ongoing work to improve vehicle safety and reduce the number of people being killed or seriously injured on our roads.

These include efforts to educate owners and potential purchasers of less safe cars, as the evidence shows we are twice as safe in a five-star vehicle than a one-star vehicle.

As part of the research, WSP behavioural and road safety researchers asked over 12,000 owners of one and two-star cars in Aotearoa New Zealand if they were aware of their car’s safety rating.

April 2023: Over the past month, Bragato’s viticulture team have been out harvesting fruit from trials across multiple vineyards. It isn’t just to collect viticultural data on yield, these grapes head to Bragato's Research Winery so their research can cover the entire process from vineyard to finished wine.

Grapes were harvested for both commercial trials and Bragato’s research, including a comparison of long spur with 4-cane pruning, mealybug management options, and testing the principles behind Bragato's upcoming Next Generation Viticulture programme.

Harvest at Bragato is slow, detailed work. All the trials are handpicked from specific vines, keeping those grapes labelled so bunches can be counted, the production of each vine weighed, and sometimes berries individually counted and assessed for disease.

April 2023: What do jumping genes, vintners, and a supercomputer have in common? They are all part of a high-tech project that REANNZ (Research and Education Advanced Network New Zealand) has been working on with the New Zealand eScience Infrastructure (NeSI).

Scientists and researchers have teamed up with REANNZ and NeSI to bring a new device to New Zealand that can unlock the tightly held secrets of naturally occurring organisms, from microbes to hops.

The PromethION genome sequencer offers users high-output, high-throughput sequencing of RNA and DNA. It’s being used here in New Zealand as part of a collaboration between Lincoln University, Bragato Research Institute, REANNZ, and NeSI.

Two research projects are already set to benefit from the new technology.

April 2023: Dr Alissa Cait is a postdoctoral researcher working in the Gasser Lab to uncover the relationship between the trillions of microorganisms in our body, called our microbiome, and immune health. From her research, she has gleaned some fascinating lifestyle insights.

“I’m really interested in how factors such as the food we eat or the environment we’re exposed to affects the populations of bacteria in our microbiome and how this then affects our immune function,” says Alissa.

The microbiome is no small part of the body. It is estimated that about 2-3kg of an average person’s body weight is microbiome.

“Each part of our body is a niche environment which hosts a unique array of microorganisms. This can include bacteria, viruses, fungi, and even certain parasites,” says Alissa.

April 2023: Ten years after completing his PhD at the Malaghan Institute, Dr Marcus Robinson recently returned to share the research he currently conducts as a Senior Research Fellow at Monash University in Australia.

“I remember the journal clubs we had at the Malaghan, which were always full of hearty discussion. You had to be sure to prepare by reading the paper beforehand, as the PhD students would be called on at random to present figures from the study. It was a refinement by fire, or at least it felt like it! It proved invaluable training in the longer term,” says Dr Robinson.

With Professor Graham Le Gros as his supervisor, he investigated what can make milk proteins allergens.

Originally from Whanganui, Dr Robinson came to the Malaghan Institute to do his PhD after studying at Victoria University. Photo: Malaghan.

April 2023: A biologist who found her passion through a school project that won a Cawthron Marlborough Environment Award is nearing the end of a 20-week scholarship working on sea grass research and restoration around Nelson’s estuaries.

Demi Fearn is one of seven tertiary students who gained a place on Cawthron’s 2022/23 summer scholarship programme.

“About half way through last year as uni was coming to an end, I was figuring out what I wanted to do next and I saw the scholarship advertised. I thought ‘wow – this is so me’.”

Demi’s scholarship saw her mentored by scientists from Cawthron’s Restoration Ecology Team, working on a seagrass restoration project.

April 2023: Five years after commencing the biggest survey of lake health in Aotearoa New Zealand’s history, Lakes380 Programme leaders at Cawthron Institute and GNS Science say there has never been a stronger call to action for New Zealanders to work together to improve the health of our lakes.

“Unfortunately, the news isn’t good, with the results of our surveying and modelling revealing that over 80% of lakes in the North Island and 45% nationally are in poor or very poor health,” says programme co-leader Dr Susie Wood of Cawthron Institute.

These results align very closely to the findings of the Our Freshwater 2023 report, released by the Ministry for the Environment and Statistics New Zealand on 12 April, confirming the seriousness of the challenges facing Aotearoa New Zealand’s lakes.

April 2023: A study from design and engineering firm WSP commissioned by the AA Research Foundation (AARF) has found that new road bypasses in Aotearoa New Zealand are significantly improving crash and injury statistics. According to the study's findings, the bypasses are resulting in fewer motor vehicle accidents and injuries compared with surrounding areas.

The study looked at seven new bypasses constructed between 2009 and 2016 – Auckland's Northern Gateway, Tauranga’s Eastern Link, Wellington’s Mackays to Peka Peka Expressway, the Waikato Expressway, and bypasses in Cambridge, Ruby Bay, and East Taupō.

WSP compared before and after crash statistics in ‘areas of interest’ using data in Waka Kotahi’s Crash Analysis System (CAS). The areas of interest included the new bypasses, the old roads and associated intersections.

April 2023: HERA has recently published a new guide, HERA Report R4-155 – Optimised Sliding Hinge Joint (OSHJ): Design and Installation Guide for a Low Damage Seismic Resisting System, which introduces a number of significant updates for seismic design using structural steel with sliding hinges in Aotearoa New Zealand.

The report has been authored by Dr Shahab Ramhormozian and Prof G. Charles Clifton from the University of Auckland.

Low-damage seismic solutions not only improve building resilience and people’s safety in an earthquake, but also have a significant role in facilitating structural steel reuse afterwards. Additionally, the OSHJ provides a low-damage, highly seismic resilient, versatile, and cost-effective seismic resisting connection option for Moment Resisting Steel Framed (MRSF) buildings.

March 2023: A new clinical study facilitated through the Cawthron-led ‘Musseling Up’ research programme has confirmed that Greenshell mussels can help reduce knee pain in post-menopausal women.

Researchers at Massey University carried out the study, finding that after 12 weeks of taking mussel powder, participants reported significantly less joint pain in their knees. The study has been published in the global journal Frontiers in Medicine.

The scientists concluded that taking the mussel powder may slow down the degradation of type II collagen in post-menopausal women who have knee pain or discomfort.

Musseling Up Programme lead Dr Matt Miller says the benefits would equally apply to whole mussels and other mussel products.

March 2023: How do children’s brains work and how do their bodies move? For millennia, medicine has often viewed children as adults in miniature – but this may not be so.

In a world-first, researchers from the Mātai Medical Research Institute and the Auckland Bioengineering Institute (ABI) have created a roadmap to mimic and analyse the structure and function of children’s brains, hearts, lungs, and musculoskeletal systems. The models developed from this work may pave the way to benchmark normal paediatric structure and function enabling more accurate diagnoses and tailored treatment for children in New Zealand.

Over 30 researchers contributed to the first phase of the study. Dr Haribalan Kumar, Mātai Research Engineer and GE Healthcare Clinical Scientist says scanning “head to toe — in the same session — for the same child” is a world first.

March 2023: In the April issue of Canterbury Farming Newspaper, Aqualinc's Matt Bubb talks about why it's important to test your effluent pond, to make sure it's not leaking.

He writes that most dairy effluent storage pond owners believe that their ponds are not leaking, particularly those that have been synthetically lined.

"However, even with synthetic lining, it is not possible to be sure that the pond is not leaking without carrying out a test. Therefore, it is important for dairy farmers to have their effluent storage ponds tested to ensure that they are not leaking."

One of the drivers for proving that effluent storage ponds are not leaking, is the need for farms to operate at a minimum of Good Management Practice (GMP). Ideally the farming operation should be operating at better than GMP.

Accurate testing is essential to insure that effluent ponds are meeting the required standards. Photo: Aqualinc.

March 2023: Cawthron is a founding partner of Moananui, a new organisation based in Nelson focused on accelerating the growth of the blue economy.

With government co-funding, Moananui’s aim is to enable businesses, government bodies, and other experts to work together to fast-track growth of the ‘blue economy’ – marine activities that generate economic value and contribute positively to social, cultural, and ecological wellbeing. More than 400 marine-related businesses and more than 30 percent of New Zealand’s fishing, aquaculture, and seafood processing are based in Te Tau Ihu (the top of the South Island), making Nelson the natural place to establish the cluster.

March 2023: Victoria University of Wellington and the University of Auckland have been named as co-hosts of a government-funded Ribonucleic Acid (RNA) Development Platform. The platform is supported by the Malaghan Institute of Medical Research and the University of Otago, with Dr Kjesten Wiig of the Malaghan Institute and Prof. John Fraser of the University of Auckland as the interim co-directors of the platform.

RNA technologies played a key role in the development of COVID-19 vaccines and this breakthrough has created significant opportunities for the technologies to be used in novel therapeutics, diagnostics, and vaccines. These technologies will also have application in other fields, including animal health and agriculture.

Initial funding of $500,000 is being provided to the RNA Development Platform to prepare a seven-year research plan. This plan will be supported by a further $69.5 million over seven years to support capacity- and capability-building in the sector.

The platform will bring together RNA researchers from around the country.

March 2023: For an orchardist to know how big their harvest is likely to be, the fruit must be counted.

But that counting can be time-consuming and tedious – and needs to be done not once, but at least twice. First orchardists count how much fruit has set, and how much needs to be thinned to ensure maximum quality. Then they need to count again, to check that the thinning has been done properly.

A successful six-year Lincoln Agritech project funded by the Ministry for Primary Industries (MPI) and New Zealand Apples and Pears Inc (NZAPI) to develop a counting app, is set to make a real difference.

The project involved capturing thousands of images of flowers, fruitlets and fruit counts on trees to train a specialised artificial neural network (ANN) called a convolutional neural network (CNN) designed to extract and interpret features from the images. These features are then combined in a model to form regions that are classified into fruit and non-fruit, providing a crop load estimate.

March 2023: BRANZ has made a bulletin available to assist with the putting right that is so important after a flood. It covers health and safety considerations, tips for cleaning up inside and outside, drying out the house, and repairs. The bulletin updates and replaces Bulletin 455 Restoring a house after flood damage. It does not cover making residential properties resilient to flooding.

Once building access is safe and services such as electricity are turned off or made safe, flood debris should be cleared away quickly so drying can start as soon as possible.

Finishing work must not begin until the building is fully dry. Beginning work too soon may result in longer-term damage such as mould growth and timber decay.

The building owner should contact their insurance company as early as possible and follow the insurer’s instructions. Work on the building should not begin until the owner has confirmed that the insurance assessor has visited and/or the insurance company has authorised the work to go ahead.

March 2023: The days when sustainable house design was just a cosy nice-to-have will soon be behind us. The government has flagged significant upcoming changes in its Building for climate change programme and other workstreams.

The benefits of good sustainable design have been understood since the 1970s, but they are still far from standard in many houses in Aotearoa New Zealand. You don’t need to look hard to find new homes where the carbon footprint is enormous, the north-facing garage steals the winter sun, the large south-facing glazing makes for chilly nights and the power bills are eyewatering.

BRANZ/Massey University research has found newly constructed houses were responsible for five times more emissions than they should be if our houses are on track to reach a net-zero goal by 2050. At the same time, BRANZ is hearing from around the country that a growing number of clients, including families looking to build a new house, are bringing up the topic of carbon footprints with their designer.

March 2023: A preclinical study evaluating a Kiwi-made Covid-19 vaccine – Kiwi Vax – has shown its unique formulation induces a safe and highly effective immune response to SARS-CoV-2 variants of concern, making it a promising booster vaccine candidate.

Published in iScience, the study findings show that Kiwi Vax, developed by Vaccine Alliance Aotearoa New Zealand – Ohu Kaupare Huaketo (VAANZ) as part of the Government’s Covid-19 vaccine strategy, is highly immunogenic, robustly expressed, and has a strong stability profile. The vaccine was independently tested at the National Institutes of Health in the United States and at the University of Melbourne.

“These findings not only show we have developed a promising booster vaccine candidate, but that we have the expertise, capability and experience within New Zealand to make our own vaccines – something that stands us in good stead for future pandemics,” says the Malaghan Institute’s Dr Kjesten Wiig, Executive Director of VAANZ.

March 2023: In 1988, Cyclone Bola caused extensive damage to the North Island in the regions of Gisborne and Northland. The destruction caused by both cyclones was similar in many respects: flooding, silt deposition in vineyards around harvest time, damage to the trellis system, vines falling over, or, in extreme cases, vineyards completely destroyed. Some remediation and recovery approaches applied with Bola are relevant to the damage experienced by Cyclone Gabrielle.

Researchers at Bragato have put together a fact sheet which addresses typical vineyard issues associated with the storm damage along with suggested solutions, gathered from growers who dealt with Cyclone Bola in 1988. They are not prescriptive but should be adapted to specific situations given that the extent of the damage may vary within a single vineyard block and across different vineyards within the same area.

February 2023: Verum Group’s Dr Laura Molles is a behavioural ecologist with a particular interest in animal communication. She has worked on several field-based projects around the US and in Costa Rica before moving to New Zealand in 2000. Here in New Zealand she has studied kōkako, kakapo, little blue penguins, bellbirds, tūī, and great spotted kiwi, including working on reintroductions and other projects that integrate behaviour and conservation biology.

“I’m originally from Southern California, where I grew up in a neighbourhood bordered by three freeways and a river with concrete banks. But nature is everywhere! There are always interesting critters to watch, even in the middle of a city. I’ve also had the good fortune to study animals in deserts, forests, and grasslands in the US..."

February 2023: Researchers at Gillies McIndoe Research Institute have recently published two new open-access papers in international journals. The first paper, by Matt Munro and published in ‘Organoids’, Applications for Colon Organoid Models in Cancer Research, outlines methods for generating colon organoids from patient-derived normal and tumour tissues. The researchers also discuss organoid biobanking, applications of organoids in disease modelling, and a range of platforms applicable to high-throughput drug testing.

The second paper, with research lead by Dr Freya Weth, was published in 'Cells' in December. The paper, Utility of the Cerebral Organoid Glioma 'GLICO' Model for Screening Applications, reviews the recent literature on the use of patient-derived glioblastoma organoid models and their applicability for drug screening, as well as provide a potential workflow for screening using the GLICO model. Glioblastoma is an aggressive and virtually always fatal brain tumour.

February 2023: The first of the Speaker’s Science Forum series for 2023 was held on 21 February at Parliament. The central focus of the forum was the major risks to food security in Aotearoa New Zealand and how we can prevent or mitigate these issues to ensure a food secure future.

Dr David Rankin, GreenTech Group Leader at Lincoln Agritech, gave a presentation saying that climate change is altering our weather patterns and increasingly affecting regional food production and hence food security. As key agricultural and horticultural areas in Aotearoa New Zealand are becoming hotter and drier, he asked will we be able to continue to produce enough food for 40 million people?

Dr David Rankin outlining how impacts of climate change on food production can be proactively mitigated. Approaches range from animal and pasture breeding efforts to food additives and wearable tech for cattle.

February 2023: Horticulture feeds our country and is a vital part of the New Zealand economy. Those in the sector have a reputation for taking on hard work and getting it done, often in challenging conditions.

Between 2016 and 2020, the number of ACC claims in horticulture remained relatively steady, however, there was a spike in 2021. In partnership with Horticulture New Zealand, Mackie Research is working with industry experts to look at how work is done in horticulture, the patterns of harm that are emerging, what is already in place to manage harm and support wellbeing, and what further system capabilities could be built within the sector.

Mackie Research have recently published a report Building Systems Capability to Reduce Harm in the Horticulture Sector.

February 2023: Motu Fellow Phoebe Taptiklis has come up with some life-saving, evidence-based information for people in cyclone-ravaged areas of Aotearoa New Zealand.

Accidental carbon monoxide poisoning kills several people a year in New Zealand. Deaths increase during long-term electricity outages, such as the current outages after Cyclone Gabrielle, as people often bring gas-fuelled appliances (like barbeques and generators) inside for cooking. Burning fuel indoors with bad ventilation can mean a dangerous build-up of carbon monoxide – a colourless, odourless gas. The gas, though slightly lighter than air, diffuses throughout the room.

BBQs are designed for outdoor use and are not as well sealed as other indoor appliances. Generators immediately underneath an open window can also cause carbon monoxide poisoning.

February 2023: Flooding from Cyclone Gabrielle has devastated regions of Hawke’s Bay. Satellite data allow for an indicative assessment of the extent of the flooding at the time of image collection. Dragonfly Data Science has released Hawke’s Bay flooding data derived from a Copernicus Sentinel-1 satellite.

An interactive map of the flooding from Cyclone Gabrielle in Hawke’s Bay, involving input from Dragonfly was published by The Herald, and is available on the Dragonfly website, along with the underlying data.

The imagery was processed in Google Earth Engine, using methods based on those recommended by the United Nations Platform for Space-based Information for Disaster Management and Emergency Response.

SAR (synthetic aperture radar) imagery is well suited for mapping floods since the data acquisition is possible regardless of the cloud cover and SAR images can be captured day and night.

February 2023: Marine Biologist Dr Bailey Lovett writes about why biosecurity matters.

"When I tell people I’m a marine biosecurity scientist, the response I get is often something along the lines of “marine biosecurity huh, that’s a niche area…” (I understand of course – it’s a bit of a mouthful. The description of what the role involves isn’t necessarily in the name, unless you know what you’re looking for).

"However, if you’ve seen any of the recent news headlines about international cruise ships being stopped from visiting certain parts of New Zealand because they were carrying oysters, snails, and various other hitchhiking critters, you might begin to understand why I don’t think that marine biosecurity is niche at all. In fact, you probably encounter biosecurity issues a lot more than you think."

February 2023: When research scientist Jin-Hua Li was a child she didn't know what scientists did, but thought it seemed interesting.

"When I was growing up, I wanted to be a scientist. I was in year 5 in my primary school, and one day our teacher asked every child what we wanted to do when we grew up. Most children said they wanted to be a teacher, but I said I wanted to be a scientist. I knew what kind of work teachers do, but didn’t know at all what kind of work scientists do, and I could see teachers every day, but had never seen a scientist. I was just curious about what scientists looked like, and what they did every day."

Research Scientist Dr Jin-Hua Li is a plant pathologist for Lincoln Agritech. Her work involves lab work, office work, nursery work, and fieldwork – including sometimes working in a forest. "Mainly I work on beneficial micro-organisms that fix nitrogen, or make phosphate soluble in soil, or help to control some plant pathogens." Photo: Lincoln Agritech.

February 2023: The recent pandemic has heralded advancements in RNA technology and as the Covid storm calms, we are left with a clear sight of the potential this technology has in our future. Dr Rebecca McKenzie works in the Hugh Green Cytometry Centre at the Malaghan Institute. As the powerhouse of the institute, the Hugh Green Cytometry Centre houses state-of-the-art research technologies, among these is New Zealand’s first end-to-end preclinical RNA therapeutics platform.

“Thanks to significant donor funding and capability built as part of Vaccine Alliance Aotearoa New Zealand, we can now carry out all the steps to develop an RNA-based therapy – from designing a template for a unique target, synthesising the RNA molecules and packing them for safe delivery to the body. We can then do the preclinical testing to understand if an appropriate immune response is triggered,” says Rebecca.

February 2023: HERA again hosted the 2023 Rotary National Science and Technology students at HERA House to kick off the new year.

As part of their commitment to inspire future engineers to work in the metals industry, this student event showcases and highlights the real opportunities that exist within the sector.

This year's cohort consisted of 22 students who are seeking further insight into potential future career pathways.

Despite Covid-19 bringing a halt to things for a short while, HERA has been hosting this event for a few years now, and their general approach is to invite their technical team to deliver concise presentations on their role at HERA, how they got there, and what it entails.

February 2023: Lincoln Agritech has again provided an internship for a rangatahi (young person) with the help of Pūhoro STEMM.

Summer intern Taylor Te Puni (Te Āti Awa) is now starting his second year of a BSc in biochemistry at the University of Canterbury, even more enthusiastic after spending the summer working with Lincoln Agritech’s Biotechnology group.

“It’s much better than other holiday jobs I’ve had!” he says. “I’ve experienced working in a scientific setting. I’ve done DNA extraction and I’ve seen how labs actually work.

Pūhoro intern Taylor Te Puni (front left) says one of the best things about working at Lincoln Agritech was working in the laboratory with Research Scientist Jin-Hua Li (front right). He’s also received mentoring from many others, including Biotechnology Team Leader Simon Kelly (back left) and Cultural Advisor Chaz Doherty (back right). Photo: Lincoln Agritech.

February 2023: International film-maker and journalist Mikey Kay says it has been “an honour” shooting an episode of the latest season of On the Frontlines docuseries in Gisborne.

Kay left the city “with a full heart” after filming a piece on the Mātai prostate cancer project and concussion research.

In the early months of the Covid-19 pandemic, GE Healthcare launched the On the Frontlines series to capture the efforts and response of the healthcare industry around the world.

Over two years later the series continues to tell stories about the greatest global health challenges and innovations, and the patients, clinicians and technology involved.

February 2023: Motu Economic and Public Policy Research reports that one of its most popular papers published in the last 12 months was Valuing forest ecosystem services in New Zealand.

The paper, authored by researcher Hannah Kotula, describes several ecosystem service frameworks and outlines how these frameworks can inform land-use decisions, focusing on those involving forests. She also describes methods for valuing ecosystem services and gives examples of forest ecosystem services and draw conclusions based on existing valuation studies in Aotearoa New Zealand. The paper conveys how an ecosystem service approach could be used to capture benefits from ecosystems not often accounted for in land-use decisions.

Society depends on services and benefits provided by ecosystems. Yet, many of our actions affect ecosystems in ways that undermine long-term human well-being. Although ecosystems provide many services to society, many of these services are not accounted for in land-use decisions.

February 2023: Ariana Brown and Jackson Clarke, two of 16 Mātai Medical Research Institute interns talk to Turanga FM about their background studies, what Mātai has to offer, and how they are impacting their community as a whole.

Thanks to support from Te Puni Kokiri, Hugh Green Foundation, Turanga Health and the University of Auckland, Mātai is able to provide summer internships for a number of students from November to January.

Undergraduate interns are typically enrolled in health science, medical or engineering degrees at a national university, and from (or with ties to) Tairāwhiti Gisborne. The ten-week programme provides students with the opportunity to be involved with cutting-edge projects, working alongside a team of expert scientists, clinicians, research staff, PhD students, and Iwi health providers.

February 2023: We often hear the terms collaboration and co-design as we plan and undertake projects, but what do these mean in practice? Scarlatti's Senior research manager Denise Bewsell explores the topic.

"Let’s say you have a project with input from over 240 researchers, extension personnel, farmers, and growers. How do you empower everyone? How can people be equally heard? How can people be enabled to make important decisions collaboratively?"

Denise writes that the IAP2 Spectrum of Public Participation is a framework used internationally to help determine the level of participation required for the public's role in a public participation process. IAP2 - International Association for Public Participation - seeks to promote and improve the practice of public participation / community engagement globally through targeted initiatives that are guided by culturally adaptive standards of practice and core values.

February 2023: Aqualinc's Ross Hector studies septic tank systems and is continually looking for ways to improve them. He says it's common for rural landowners to dispose of wastewater via septic tanks or similar wastewater systems as the distance to a reticulated network is just too great.

But he says that many people with these types of systems may know little about it - exercising an 'out of sight, out of mind' policy. He says this is largely because visible on-site issues rarely occur.

"However, should a system not be functioning correctly, then concentrations of contaminants entering the environment, and groundwater in particular, may be more significant than expected."

This is especially concerning if systems are installed with close proximity to drinking water bores.

Ross writes that recent research has shown that as much as 30% of New Zealand's septic tank systems may have issues.

February 2023: As vineyards age and succumb to trunk disease, there is an urgent need for information to support replanting decision-making. The selection of rootstock is one of the most important decisions in the development of a vineyard. To address this issue, the Bragato Research Institute recently started a rootstock research programme. A new research trial was planted in October 2022 in the Wairau Valley of Marlborough. It includes 14 rootstocks combined with three levels of irrigation, with the goal of identifying rootstocks that will prepare us for a warmer and drier future.

Dr Carmo Vasconcelos reports that climate change has impacted viticulture in almost all wine regions in recent decades, primarily due to rising temperatures, changing precipitation patterns, and an increase in the frequency of extreme events, affecting grape yield and quality.

She writes that the water footprint of agriculture is also under increased scrutiny, and industries need to be prepared for future restrictions on water available for irrigation.

February 2023: Earlier BRANZ research showed mental health and suicide to be major issues facing the construction industry. This year, new research with a wider lens across all industry occupations illuminated the full extent of the issue and the demographic groups most at risk. This new perspective will enable targeted interventions and more-effective development of tailored support.

In the ground-breaking 2018 BRANZ study Mental health in the construction industry, they highlighted that construction workers were more likely than the rest of the workforce to lose their life to suicide.

A catalyst for action, the research prompted the establishment of workplace mental health programme MATES in Construction (MATES) in New Zealand in 2019.

MATES trains construction workers in offering mental health support to their colleagues and asking for help when they are struggling themselves.

Now, MATES has data from two new studies published this year, which it is using to target its interventions more effectively.

February 2023: In this RNZ article Niva Chittock reports on the work of the Cawthron Institute monitoring New Zealand's waters for harmful algal blooms - a situation that could arise more often if rising sea temperatures entice more harmful algal blooms from the sub-tropics to New Zealand's shores.

Aquaculture research scientist Dr Anne Vignier said while the exact impact of warmer ocean temperatures was not yet known, it was likely to have negative consequences for seafood.

"We're already seeing reduced resilience in commercially important fish and shellfish species with increased water temperatures, and then if you put harmful algal bloom exposure on top of that, it's an extra stress," says Dr Vignier.

Warmer sea temperatures may change how harmful algal blooms act too, she said.

February 2023: Dr John McDermott, Chair of IRANZ, Executive Director at Motu Economic and Public Policy Research, and a well known macroeconomist, addressed the Port Nicholson Rotary Club on 25 January with reference to the things that can happen in an economy when external events such as a pandemic can drive consumers, businesses, governments, and central banks to react in different ways.

To provide an example of how inflation can be generated and controlled, John referred to a 1970s story of the Washington DC Capitol Babysitters Co-op, whose purpose was to fairly distribute the responsibility of babysitting between its members. The story is often used as an allegory for a demand-oriented model of an economy. The allegory illustrates several economic concepts, including the "paradox of thrift" and the importance of the money supply to an economy's well-being.

Brent Gerrard reported on the talk for the club.

January 2023: The prospect of recession is looming ever large as central banks act to restore price stability. To understand the nature of recessions, you need a long historical record.

Unfortunately, official Aotearoa New Zealand data on quarterly real Gross Domestic Product (GDP) only goes back to 1987, limiting our ability to understand the nature of growth or frequency of recessions.

To help, Motu Research's John McDermott and Viv Hall (Professor at Victoria University of Wellington) recently updated their estimates of quarterly GDP back to 1947. This gives 75 years’ worth of economic history we can use to deepen our understanding of the Aotearoa economy.

The data is available for free on Motu's website. Download the excel file - or if you wish to access the data directly in Python, R or EViews - use the code provided on our website.

January 2023: About 10 minutes is all it takes for the air in a room to be exchanged with fresh air if you open windows on different walls. This helps remove or reduce particles that may be carrying viruses. This advice from the Indoor Air Quality Research Centre, which BRANZ helped establish, led to teachers ventilating classrooms as part of the COVID-19 response.

There are invisible dangers harbouring in the air inside some buildings that mean people might not be as safe indoors as they believe. Assembling the best minds in the country on ‘all things indoor air quality’ is helping to propel research in the field. This is in a bid to better understand the health effects and to find solutions to improving poor indoor air quality.

Experts from seven leading research organisations came together to form the Indoor Air Quality Research Centre (IAQRC): BRANZ, GNS Science, NIWA and the universities of Canterbury, Massey, Otago and Victoria.

January 2023: The endemic ground wētā, Hemiandrus bilobatus, lives in burrows in the soil, but its presence can negatively affect wine grape production. This is especially so in vineyards in the Awatere region in Marlborough. Vine growth in early spring provides the ground wētā with a buffet of fresh buds to feed upon, which causes damage detrimental to vine growth and fruit yield.

The current ground wētā management tool sees plastic sleeves wrapped around vine trunks in an attempt to prevent wētā from accessing the cordon. However, the sleeves are costly to install and maintain, resulting in a significant waste-management issue.

A Bragato research team is hoping to develop an environmentally and economically sustainable solution to the growing problem of ground wētā. Among the issues they write about are identifying wētā burrows during the day. It is not straightforward because the wētā make soil plugs or doors to close their burrow entrances, so they are hidden from view.

January 2023: CRISPR-Cas9 is an exciting new addition to the Malaghan Institute’s repertoire of tools to investigate the immune system.

“There will always be new technologies that allow you to expand your research or even unlock knowledge that we had no way of accessing previously. CRISPR-Cas9 is one of those technologies,” says Dr Olivier Lamiable.

Olivier, a member of the Ronchese Lab at the Malaghan Institute, is a team leader using revolutionary CRISPR-Cas9 technology to understand how allergic diseases develop on a cellular and molecular level.

“It allows us to precisely modify, add or remove specific parts of the DNA of live cells in a way that is faster and easier than any method before.”

Dr Olivier Lamiable is working to understand which genes are involved in the function of a molecule that might be involved in conditioning T‑cells to react and drive allergic responses. Photo: Malaghan Video.

January 2023: The future's looking brighter for a new generation of kauri trees. Working with scientists, rongoā Māori practitioners say they're close to finding a cure for kauri dieback disease.

Journalist Te Rina Kowhai from TV3's Newshub interviewed scientists Dr Amanda Black (soil scientist) and Dr Nick Waipara (plant pathologist) from Te Tira Whakamātaki (TTW) about mātauranga Māori solutions in the battle against Kauri dieback disease.

"I'm optimistic that it's there, we are not there yet but we are getting there," says Nick.

But Nick cautions that more research is still needed to validate whether the soil-pathogen phytophthora agathidicida has been eradicated from the sick kauri trees treated with rongoā.

Amanda explained how the kahikatoa spray used on the soil to treat the sick kauri, uses a mix of mānuka and kānuka and scientists have found that flavonoids from kānuka do inhibit phytophthora - the microorganism which causes kauri dieback.

The item aired on 10 January 2023.

January 2023: In August 2022, devastating floods hit the top of the South Island, destroying aquatic life in its rivers and estuaries.

Journalist Alexa Cook from TV3's Newshub interviewed scientists from the Cawthron Institute about the ongoing impact from the event, which is believed to have killed 80 percent of the fish in Nelson's Maitai River. The scientists say it will take years for the area to recover.

"There's very little life - I'd expect a range of caddisflies, snails, perhaps some worms, mayflies," says Cawthron freshwater scientist Roger Young.

Those critters were stripped from their home when the meandering Maitai turned into a raging torrent. It left an almighty mess and killed at least 80 percent of the eels, trout, whitebait and other fish living in it, Alexa reported.

"It was pretty devastating. There weren't many fish in the river for a while, and very little for them to eat," says Roger.

The item aired on 10 January 2023.

January 2023: Researchers at Nelson’s Cawthron Institute welcomed aquaculture technicians from the Pacific Islands last month for a four-week knowledge exchange project funded through a joint Pacific Island government initiative.

Tuaine (Tutu) Turua, from the Ministry of Marine Resources in Rarotonga, Cook Islands, and Rennie Reymond, from the Ministry of Fisheries and Mineral Resources Development in Kiribati were recently hosted at the Cawthron Aquaculture Park in Glenduan, Nelson, for four weeks.

Tutu Turua and Rennie have backgrounds in mariculture (marine farming) and hatchery production of various native species of commercial and cultural interest for the Pacific communities (e.g., pearl oysters, sea-cucumbers, giant clams, seaweed, freshwater prawns).

“The aim of our visit was to learn from Cawthron researchers’ shellfish hatchery expertise and take that knowledge back home to support our local shellfish industries."

January 2023: Dr Kyuhan Kim visited his home town in September and October 2022 for the first time in nearly three years. Not only was it an opportunity to see his family again, but also to share his research in best-practice fisheries science.

Kyuhan presented part of his PhD research at the annual meeting of PICES. PICES is an intergovernmental science organisation that coordinates marine research in the North Pacific. Member countries include China, Japan, Russia, US, Canada and South Korea. This year the meeting was conveniently held in his hometown of Busan.

“I spoke about the stock assessment models I developed at university and in my work at Dragonfly. I suggested some possible improvements for the current methods. About 30 people were in my session, and there was quite a lot of interest in my work.”

Kyuhan also spent time sharing his knowledge with the staff and marine biology students at Pukyong National University, where he studied for his masters degree.

January 2023: Bragato Research Institute is gearing up to ‘evolutionise’ Sauvignon Blanc, thanks to six scientists and a newcomer called PromethION.

Dr Darrell Lizamore leads the Sauvignon Blanc Grapevine Improvement Programme (Sauvignon Blanc 2.0) out of a laboratory at Lincoln University. He says the programme isn’t traditional breeding, crossing or genetic modification, but a mission to sequence the DNA of New Zealand Sauvignon Blanc, looking for patterns of increased natural mutation that may help vineyards respond to future challenges. “Plants have an innate ability to change their own genetics when confronted with an environmental shock. If we can use this response to produce vines with different traits, then we could select those better suited to future viticulture.”

January 2023: A long-term study of the sustainability of new homes shows not a lot has changed in the past decade. While there has been significant growth in sustainability services, most homes are still built to basic Building Code requirements. It seems that sustainable housing won’t increase until the Code requires it says BRANZ Building Scientist James Sullivan.

Since 2012, BRANZ has been tracking the sustainability indicators of new detached housing constructed in Aotearoa New Zealand. A study is carried out every 4 years, most recently in 2020 and focusing on random samples of newly consented detached houses in Auckland, Hamilton and Christchurch.

James writes that of the 210 houses examined in 2012, none could generously be classified as high performance with multiple elements having significantly above Code R-values. In the 2016 and 2020 samples, there were a few (7 and 5) – all in Christchurch.

January 2023: The Ka Mātau, Ka Ora study is the largest evaluation of COVID-19 vaccine immune responses in New Zealanders, focusing on some of the populations at higher risk from COVID-19, such as Māori, Pasifika, the elderly and those with comorbidities.

The latest data shows a first booster dose significantly improves the ability of vaccine-induced immune responses to neutralise viral variants, including Omicron, across all demographic groups, following a period of waning immunity after a second dose.

“The results are a clear call to action to the nearly one million New Zealanders eligible but yet to get their first booster,” says Dr Maia Brewerton, Clinical Director of Vaccine Alliance Aotearoa New Zealand – Ohu Kaupare Huaketo (VAANZ) which led the study.

“Vaccination continues to be one of the best tools we have for protecting ourselves and our whānau from getting really sick from COVID-19. But two doses isn’t enough – at least one booster dose is key against Omicron, particularly for people vulnerable to more severe COVID-19 disease, including our Māori and Pasifika populations.”
