Crown Research Institutes

Crown Research Institutes (CRIs) are Crown-owned companies that carry out scientific research for the benefit of New Zealand.

On this page

CRIs play a unique and important role supporting their sectors to innovate and grow. They strive to address New Zealand’s most pressing issues and achieve economic growth by improving sectors’ productivity and improving the sustainable use of natural resources.

There are 7 CRIs, each aligned with a productive sector of the economy or a grouping of natural resources. They are:

• Institute of Environmental Science Research (ESR)
• Institute of Geological and Nuclear Science (GNS Science)
• Landcare Research
• National Institute of Water and Atmospheric Research (NIWA)
• Plant and Food Research

Each CRI's purpose

The purpose of each CRI is set out in the table below. For more information about the CRI go to their websites.

Governance of CRIs

The CRIs have 2 shareholding ministers who act to protect the Crown’s investment in CRIs, the Minister of Science and Innovation (external link) and the Minister of Finance (external link) .

The governance structure for all CRIs is the same — shareholding ministers appoint CRI boards of directors, who in turn appoint the chief executive in accordance with the Companies Act and the constitutions of each CRI.

Our relationship with CRIs

Our ownership and performance role is to monitor the Government’s investment in CRIs. As part of this role we:

• provide strategic ownership advice to the shareholding ministers on the financial and non-financial performance of the CRIs
• work with CRIs to ensure they can deliver optimal outcomes for New Zealand
• help appoint directors to CRI boards.

The document "Monitoring arrangements for MBIE-monitored Crown entities" outlines the accountability and performance framework in which CRIs operate. Particular information relating to CRIs is included in Annex 7 of the document.

4-Year Rolling Reviews

The 4-year Rolling Reviews provide shareholding ministers with an independent assessment of each CRI’s current effectiveness and future potential in delivering on the purpose and outcomes set out in its Statement of Core Purpose.

The reviews provide insights on where performance can be improved and assurance on where the CRI is operating effectively in delivering outcomes that contribute to New Zealand’s economic, social and environmental well-being.

The reviews are an assessment of governance effectiveness, financial viability and sustainability. They also identify opportunities, barriers to success and alignment to government priorities.

What the reviews found

Findings from the reviews support CRI boards in their governance and decision-making roles. The reviews are conducted every 4 years and involve an independent panel working for up 15-20 days. The panel’s work includes document examination, interviews with the CRI board, management and staff; and interviews with major end-users and stakeholders.

The review panels have consistently found:

• a strong commitment to science that benefits New Zealand
• the organisations are underpinned by solid practices, processes and policies
• good relationships with key customers.

They also found the CRIs would benefit from:

• a clearer strategy
• strengthened partnerships and interactions with Māori
• delivery of future financial projections.

Government backs largest ever pastoral farming study on regenerative farming practices

New Zealand’s largest ever study on the sustainability of our farming sector aims to prove to the world why New Zealand food and fibre should be always the number one choice, Agriculture Minister Damien O’Connor announced.

“The Government is backing a new $26.1 million programme to undertake the most comprehensive study of pastoral farming in New Zealand,” Damien O’Connor said.

“New Zealand’s economic security depends on our primary sector, which this year earned us a record $53.3 billion in exports. Our future competitive edge in food and fibre will depend on demonstrating our sustainability credentials to ever more discerning consumers.

“The new Whenua Haumanu programme will study the whole pastoral farming system from field to fork.

“It will scientifically build a picture that includes soil biodiversity, pasture performance, animal production and welfare, and the quality of the food produced.”

  Whenua Haumanu is being led by Massey University’s School of Agriculture and Environment to enable farmers to make informed decisions on the financial and environmental benefits of adopting regenerative farming practices.

“We’re committing $17.6 million over seven years through the Ministry for Primary Industries’ Sustainable Food and Fibre Futures (SFF Futures) to fund this partnership,” Damien O’Connor said.

The programme will involve several research sites and bring together universities, Crown research institutes, and industry groups. Research partners include AgResearch, Lincoln University, and Dairy Trust Taranaki. Additional guidance will be provided by an End User Advisory Group comprised of the pastoral industry, iwi, investment and consumer groups.

“This is the most comprehensive study ever undertaken of our pastoral systems, both conventional and those incorporating regenerative farming practices,” Damien O’Connor said.

“Whenua Haumanu will be part of broader coordinated work that the Government is backing to provide a robust evidence base to explore regenerative farming practices alongside conventional pastoral practices in both dairy cow (cattle) and sheep systems. In doing so it will also test claims that many of our conventional pastoral practices are already regenerative.

“One key aim of the programme is to investigate potential benefits of diverse pastures for grazing animals, as well as regenerative farming practices, as these have yet to be thoroughly studied for the New Zealand farming context.”

Damien O’Connor said establishing an evidence base of regenerative practices is a cornerstone of the sustainability goal in the Government and food and fibre sector’s Fit for a Better World roadmap.

“Through SFF Futures we are co-investing with others in 11 research projects across the country that are evaluating regenerative farming practices. These amount to a total investment of $54.74 million from Government and investment partners, and further research proposals are being assessed by the Ministry for Primary Industries.

“Developing a sound evidence base for what works well with our soils, climates, and farming systems will aid our efforts to transition to a more sustainable future for our food and fibre sector.

“Purchasing decisions by consumers in our export markets are increasingly being driven by their values. The work by Whenua Haumanu will help New Zealand tell the story of its food production so we can grow exports and deliver economic security,” Damien O’Connor said.

• Our history

Professional scientific research to aid agriculture and horticulture in New Zealand dates back to the early 1900s - Plant & Food Research is part of this long history and still operates from some of the original buildings of the DSIR.

1926 - The Department of Science and Industrial Research (DSIR) formed after pressure from scientists – including the celebrated Lord Rutherford – and the recommendation of a visiting British expert.

1928 - DSIR joined with the Department of Agriculture in establishing a Plant Research Station.

1936 - Plant Research Station was transferred entirely to the DSIR - The DSIR begins doing its own research rather than coordinating other institutions. Five separate research divisions were created:

Grasslands in Palmerston North

Plant Diseases in Auckland

Entomology, attached to the Cawthron Institute in Nelson

Soil Survey (later Soil Bureau) in Taita, Wellington

Agronomy (later Crop Research Division) in Lincoln.

1948 - Fruit Research Station created, which found ways to combat orchard pests and diseases, and bred new varieties of apples and other fruit.

1962 - Plant Physiology Division was created at Palmerston North, special ‘climate control’ rooms set up where temperature, day length and humidity could be varied to study the effects on plant growth.

1970 - Applied Biochemistry Division set up, investigating the biochemistry of plant materials.

1980 - Horticulture and Processing Division formed.

1992 - On 1 July 1992, Ten Crown Research Institutes (CRIs) were established out of former government departments:

Department of Scientific and Industrial Research (DSIR)

MAF Technology out of the Ministry of Agriculture and Fisheries (MAF)

Forest Research Institute out of the Ministry of Forestry

Part of the Meteorological Service of the Ministry of Transport

Health Service Laboratories of the Ministry of Health.

The CRIs formed included:

The Horticulture and Food Research Institute of New Zealand (HortResearch)

The New Zealand Institute for Crop and Food Research (Crop & Food Research)

The New Zealand Pastoral Agriculture Research Institute (AgResearch)

The Institute of Environmental Science and Research (ESR)

The New Zealand Forest Research Institute Limited (Scion)

The Institute of Geological and Nuclear Sciences (GNS)

Industrial Research Limited (IRL)

Landcare Research New Zealand (Landcare Research)

National Institute of Water and Atmospheric Research (NIWA)

The Institute For Social Research and Development - disestablished in 1995.

2008 – On 1 December 2008, Plant & Food Research formed following the merger of former CRIs HortResearch and Crop & Food Research.

Crown Research Institute outlines priority research topics including data management, biosecurity and animal welfare

Government support for agricultural research is “critical” to the future of pastoral farming in New Zealand, a study has found.

In a paper published in December in the Journal of the Royal Society of New Zealand, researchers from the AgResearch Crown Research Institute, its subsidiary Grasslanz and Lincoln University write that “pastoral agriculture in New Zealand faces several challenges and opportunities that will require continued research and development to provide effective solutions”.

Insight into Regenerative Agriculture in New Zealand

The good, the bad, and the opportunity of regenerative farming.

Alina Siegfried

Edmund Hillary Fellowship

In November, 2019 a group of 85 farmers gathered in a mixed cropping farm and a dairy farm near Leeston, Canterbury, to find out what they could learn about regenerative agriculture. They marvelled at the lush pasture, dug in the rich black foot-deep top soil, heard stories from their peers, and visited some happy, healthy cows. The field day organisers were blown away by the attendance and enthusiasm of the crowd.

There is a fast growing movement in New Zealand that has been happening out in paddocks, fields, gardens and hill country across the nation. It is a movement that holds the promise to reshape our productive land use industries towards systems that work with the natural environment to regenerate the land. The movement is that of regenerative agriculture .

We are in the midst of a global pandemic, and facing a very different future than we could have imagined just a few short months ago. Almost every part of our lives is up for re-assessment as much of the global economy and international trade has ground to a halt. COVID-19 has shaken up our very understanding of what is “normal”, presenting a mirror in which we can see the chance to reshape a new future. The situation has been described as a test run for the environmental crises to come if we don’t address climate change, biodiversity loss, and other ecological degradation together. As pointed out by Rod Oram , in a time of great upheaval we can use this as an opportunity to re-imagine New Zealand’s economy and our agricultural heartland to collectively work better for our planet and people.

Regenerative Agriculture (regen ag) is a term that was first coined by the late Bob Rodale in the 1970’s. He used it to summarise a set of farming principles and practices that enrich soils, improve watersheds, enhance ecosystem services such as soil carbon and nitrogen sequestration, improve biodiversity, and promote farmer and livestock welfare. Definitions and principles vary a little depending on who you talk to (see the resources linked below), and regen ag is achieved through the practices and processes of a number of related land management approaches including; organic farming, holistic land management, permaculture, biodynamic farming, carbon farming, silvopasture, agroecology, and conservation agriculture.

Definitions and Principles of Regenerative Agriculture:

• The Original Principles of Regenerative Agriculture (Rodale Institute)
• Definition of Regenerative Agriculture (Terra Genesis International)
• What is Regenerative Agriculture? (The Carbon Underground)

In the context of agriculture, the terms organic and regenerative are closely linked and are sometimes incorrectly used synonymously, yet they are not the same. Organic agriculture is prescriptive in terms of inputs, eliminating the use of synthetic fertilisers and pesticides, veterinary drugs, genetically modified seeds and breeds, preservatives, additives and irradiation.

Regen ag on the other hand is not just about reducing harm, but seeks to actually improve the health of the land, waterways, the animals that live on it, and people that benefit from it.

Taking a whole-system approach, it encourages farmers to pay close attention to what individual pastures, fields, gardens, and plots of land need in order to function more like natural ecosystems, while simultaneously seeking to improve farmer wellbeing and animal welfare. In practice, that might look like zero tillage, continual cover, increased pasture and crop diversity, the use of nitrogen-fixing cover crops, the avoidance of synthetic fertilisers and pesticides, and longer rotational periods for stock to give plants a longer time to recover.

What’s driving the movement?

Largely, it is a recognition that certain conventional methods of farming are doing harm to our environment, to livestock, and to people. The agricultural sector in NZ contributes 48% of our greenhouse gas emissions . The Ministry for the Environment’s 2019 Environment Aotearoa report states that waterways in farming areas are polluted by excess nutrients, pathogens, and sediment. Computer models referenced in that same report estimate that 82% of the river length in pastoral farming areas was not suitable for activities such as swimming during the period 2013–17, based on the predicted average Campylobacter infection risk. Many of the findings unearthed during researching Our Regenerative Future support the suggestion that the widespread adoption of regen ag could help to reverse these trends.

NZ is not alone in facing these challenges. The environmental effects of conventional farming on an industrial scale are being felt across the world, threatening the stability of our planet’s climate and natural capital, placing the global food system at a critical juncture.

The Food and Landuse Coalition was set up in 2017 to urgently transform the way we use our land to produce and consume food. With a large number of high-profile, reputable supporters and commissioners, they urge a focus on restoring the soil, conserving and improving biodiversity, and ensuring the health, economic development, social well-being, and social inclusion of the global population — all goals of the regen ag movement. Adoption of regenerative agriculture at a global level also has the potential to help us achieve a number of the UN’s Sustainable Development Goals , including: #2 No Hunger; #3 Good Health & Wellbeing; #6 Clean Water & Sanitation; #8 Good Jobs & Economic Growth; #13 Climate Action; #14 Life Below Water; and #15 Life on Land.

With the rise of plant-based meat and milk alternatives and consumer choices being increasingly driven by health, environmental impact, and transparency , there are big questions hanging over our agricultural industry and NZ’s economic reliance on it. There could be a great advantage for NZ producers to start moving towards products that align more closely with consumer demands, and fetch a premium price on international markets, a sentiment that is shared by New Zealand’s Minister of Agriculture, Damian O’Connor .

In this series produced for Pure Advantage in collaboration with the Edmund Hillary Fellowship ( EHF ) and distribution partner Newsroom , I aim to provide a snapshot of the state of regen ag in NZ by telling the stories of those who are either practicing, supporting, studying or observing it objectively, and by presenting some of the challenges and highlighting the opportunities.

Many of those who are operating in this field are collaborating across sector boundaries, and embracing complexity in their work. They are the ones who are leading this brave new conversation, and going out on a limb.

Through my many varied conversations, the following themes and considerations have emerged as pertinent to scaling NZ’s nascent regen ag industry to the point where we can begin to achieve positive changes across many environmental, social and economic indicators.

Below are just a few of the levers we need to pull to catalyse the change.

Gathering the data (and finding the right way to interpret it)

While there is no shortage of anecdotal data, empirical evidence on the claimed benefits of regen ag is hard to come by in the NZ context for two main reasons. Firstly because regen ag is relatively new here, and that it can take a long time for scientific indicators to shift. Most of the studies funded so far have been too short-term to provide meaningful insights.

But the second and more pertinent reason is that there is a philosophical tension between reductionist scientific enquiries and the whole-systems view that regen ag actually takes. Reductionist scientific methodologies have contributed to generating the vast majority of our current agronomic knowledge, and as such they have merit. However, problems arise when we rely on linear indicators to make farm management decisions, without taking many others into account. Regen ag by definition views the farm as an interconnected, highly complex, and dynamic system greater than the sum of its parts, a holistic view which is better studied using complex system science and trans-disciplinary methods. This kind of science is expensive, and notoriously difficult to do.

Current research undertaken by Manaaki Whenua Landcare Research is investigating the case for regen ag, with several further studies planned. The challenge is to deploy the right methodologies and present the data in a way that provides an overview of an entire ecosystem. Read our story on Soil Ecologist Dr Gwen Grelet , who is one of the scientists leading the work on data collection in NZ.

One of the most compelling cases for regen ag is its potential for carbon sequestration, as outlined by the UN Environment. There is thought leadership and supportive international science across a number of different land management practices, but in NZ the data is sparse and siloed. The current study mentioned above being led by Dr Gwen Grelet includes the measurement of soil carbon across both conventional and regenerative pastures.

International studies have shown that greater plant diversity in grassland, one of the common practices of regen ag, improves water infiltration . A recent study conducted on corn crops in the United States, and showcased in Forbes , found that pests were 10-fold more abundant in insecticide-treated corn fields than on insecticide-free regenerative farms, indicating that farmers who proactively design pest-resilient food systems outperform farmers that react to pests chemically. The same study found that while the regenerative farmers had lower yields, they reported 78% higher profits over traditional corn production systems, due to a reduction in input costs, and higher value end markets.

On the organics front, an almost 40-year ongoing study by Rodale Institute has shown that organic farms produce 40% more yields during times of drought as compared to conventional farms, in part due to higher levels of organic soil matter.

Similarly to soil carbon, there is little peer-reviewed science from NZ on the drought resilience of organics, or the suggestion that regen ag reduces nutrient run-off from farms. I came across plenty of anecdotal examples during the process of researching this article, of farmers saying that their pastures retain more water and are more resilient to drought, after they transitioned to regen ag. A partnership between data analytics platform Takiwā and Australian company EcoDetection hopes to provide better insight into levels of nutrient runoff from individual regeneratively managed farms, using state-of-the-art nitrate and nitrite sensors. Read more about that initiative in our story on EHF Fellow Mike Taitoko .

Certification systems for organic and regeneratively produced foods

Consumers within both domestic and international markets are increasingly seeking to improve their health and reduce their impact on the planet through their food choices. There is a huge market opportunity for premium products, yet NZ food producers lack a standardised enforceable organic seal that would reassure consumers they are buying legitimate organic products. A regenerative organic standard, similar to the one recently launched in the US could be a logical next step — although at present this is a voluntary compliance, non-enforceable seal. Gary Hirshberg, an EHF Fellow and entrepreneur built Stonyfield , the largest organic yoghurt company in the US, offers NZ farmers insight into leveraging the international market for organic and regen ag. Gary is now focused on developing an organics training centre on a property near Motueka. Read Gary’s story here .

Emerging technology may also provide a means of educating and providing transparency to consumers about the quality of their food, and the corresponding levels of environmental impact associated with their production. The US-based Bionutrient Food Association is currently developing their second prototype of an open source handheld spectrometer that measures the nutrient density of fruits and vegetables, providing real-time data on levels of antioxidants, polyphenols, and flavonoids. Regenerative agriculture nurtures healthy microbial communities and grows carbon stores in the soil, which in turn produces plants with higher brix levels and more nutrient-dense food. For these reasons soil consultant Phyllis Tichinin believes spectrometer technology will be a game changer for agriculture once it becomes widely available. If it is developed into a phone app for example, which Phyllis thinks is inevitable, consumers will be able to make more educated purchasing decisions in the supermarket that align with their desires for higher quality produce, that they can be reasonably sure is farmed in a way that is more sustainable than conventional alternatives.

Government and policy support

After farm subsidies were cut in the 1980’s, the primary source of knowledge and advice for farmers shifted from government sources to industry experts and fertiliser companies. Despite a groundswell of momentum being driven by farmers, experts and advocates around the country, the bulk of the industry has been slow to come on board with regen ag. For instance He Waka Eke Noa, the Primary Sector Climate Change Commitment published in 2019, does not mention regen ag at all. The Primary Sector Council, however, is making some good progress with their Fit for a Better World initiative, while Beef + Lamb NZ has recently announced they are undertaking a global study into regen ag to understand its similarities and differences to NZ farming practices, the opportunities for farmers, and to better understand the global consumer perspective.

Provided that they are properly resourced and supported, these moves hold promise and can help inform the national conversation around land use. While there are calls from some groups to return as quickly as possible to business-as-usual post-COVID, NZ has a unique opportunity to build on our international reputation for innovation, and assist with a transition towards regen ag.

Should the Government signal a commitment to better understand the systemic benefits of regenerative practices, and put in place supportive policy with adequate investment into research and science to investigate the potential for NZ, then this could pave the way for a significant transformation of our primary sector towards becoming a truly regenerative system.

The United Kingdom is currently progressing an Agriculture Bill through Parliament that would end EU farm subsidies for productive land use in general, and replace them with subsidies for those farms providing environmental services and public goods, such as planting forests, sequestering carbon in soil, enhancing habitat with pollinator-friendly flowers, and improving public access to the countryside. While the devil will certainly be in the details, it will be an interesting example for New Zealand to watch.

Providing the support scaffolding for farmers to go regenerative

After travelling the globe meeting with 100 farmers across 18 countries, regen ag advocate and researcher Sam Lang found that a significant factor in determining whether farmers made a successful transition to regenerative agriculture was whether or not they had a supportive community alongside them. Sometimes that was their local community, but more often was an online or geographically spread community of like-minded people.

Across many different types of farms, those who had a supportive community were consistently more successful in transitioning to regenerative systems. Read our story about Sam and his experiences researching regen ag on a 2016 Nuffield scholarship.

Cerasela Stancu with Envirostrat is taking an even broader approach, and is in the early stages of bringing together a community involving leaders from across the health, nutrition, conservation, academic, and community sectors, to develop a thriving economic system that puts regen ag at the forefront. Read Cerasela’s story here .

Providing funding and coaching

Taking the leap to regen ag practices can be challenging not just in terms of changing land management practices, but with different economic models to focus on as well. Certain farms experience a temporary decrease in yields for the first few years, although margins can be higher due to reduced spending on fertiliser and improved animal health. Mike Taitoko , mentioned above, also hopes to address the funding gap by providing the much needed bridge of accountability between investment and measurable impacts through his new company Toha .

Reducing our reliance on chemical fertilisers

NZ’s reliance on imported chemical fertilisers, combined with conventional methods of farming such as intensification has led to a number of systemic and environmental problems. Nitrogen leaks through shallow-rooted pasture and spurs algal growth in rivers, which can also lead to the suppression of aquatic life. Of NZ’s total river length, 70% had modelled nitrogen concentrations above the expected range for natural conditions between 2013 and 2017. NZ also is complicit in the production of “blood phosphate”, as the only country in the western world that imports phosphate from Western Sahara, a territory occupied by Morocco since the 70’s in a move that has received condemnation from the UN. Read our story featuring EHF Fellow Kay Baxter of the Koanga Institute , and how she is tapping into natural sources of plant nutrients.

Supporting rural mental health

It has been a long-standing trend in NZ that farmers have higher rates of mental illness than other sectors of the population. Influencing factors include financial stress and high levels of debt, isolation, family issues, increasingly unpredictable climatic patterns causing adverse weather events, and fluctuating global markets over which farmers have no control. Suicide rates among rural males in NZ are significantly higher than the rate for urban males, with an average of 26 deaths per 100,000 population in rural areas, compared to 16.7 male deaths in urban settings between 2007 and 2016.

A 2018 study commissioned by Australia’s National Environmental Science Program and covered by holistic farming advocate John King for Pure Advantage showed that regenerative graziers in NSW experienced a meaningful and significant wellbeing advantage compared to conventional local farmers matched for gender and age. Regenerative graziers also reported higher ‘farming self-efficacy’ — confidence in their ability to successfully manage different aspects of their farm. Read our story featuring Jono Frew who is helping build a community of support for regenerative farmers in NZ through Quorum Sense , and reporting improvements in farmer happiness and wellbeing.

Tapping into indigenous wisdom

The term regenerative agriculture is reasonably new, yet at its core essence, the philosophy towards land management has been practiced by indigenous communities across the world for many generations, including Māori. The Toha Calm the Farm initiative, mentioned above, has partnered with the Federation of Māori Authorities ( FOMA ) to assist Māori-run farms in the transition to regenerative and biological methods of farming through FOMA’s Whenua Ora Tangata Ora programme.

Integrated and collectively owned business models that combine land regeneration, employment initiatives, and a multi-generational view, such as those being taken by Wakatū , provide great examples of how whole-systems approaches can deliver value across environmental, social, cultural and economic indicators.

A new way forward

New Zealand farmers are regarded internationally as some of the most accomplished stewards of their land, from which they produce food for Kiwis and international markets. Yet farmers face new challenges on several fronts from climate change, new environmental standards, changing consumer trends, and a post-COVID-19 global economy. Farmers are central to an economic system involving banks and fertiliser companies, and a long-standing narrative that embeds conventional and commercial methods of farming that are incongruent with regenerative practices . The collective thinking behind Our Regenerative Future is that NZ farmers have much to gain if they can find ways to join up and share the knowledge that could amplify regenerative practices. One approach is to support leaders who can help shape policy designed to unlock research funding and stimulate innovation. Simultaneously, we can equip rural communities with the know-how to ensure the NZ ag sector gains a more substantive footing in the global regen ag space.

At the risk of crystal ball gazing, early indications suggest that NZ’s early and decisive response to control COVID-19 could be held up as a positive global example, further strengthening our nation’s reputation for innovative thinking and collective action. With so many of the moving parts of our economy at a standstill, we have been gifted a chance to extend beyond the inertia of our agricultural model, and reshape it to help heal the land.

Perhaps the biggest transition that we need to make is shifting the mindset towards managing agricultural systems regeneratively.

In the conventional model a farmer asks a reductive, linear question: “What is the current problem, and how do I solve it?”. The regenerative farmer, on the other hand, will ask a holistic question:

“How do I optimise my system to work better, so that fewer problems arise?”

Having taken a deep dive into regen ag for this series interviewing many people who are involved in various ways, I propose that the latter question is the right one to be asking for our agricultural economy, our environment, and for our global climate system.

This story originally appeared on Pure Advantage , and is part of the “Our Regenerative Future ” series, which investigates the current state of regenerative agriculture in New Zealand and highlights future opportunities for its primary production sector.

Bovine tuberculosis is New Zealand's most serious animal health problem because of its threat as a nontariff trade barrier to livestock export, and because a wildlife reservoir of 70 million brushtail possums seriously constrains its control. Mathematical models have contributed significantly to current control strategies and have highlighted some key questions of wider epidemiological significance.
