Reference excerpt

The National Institute of Water and Atmospheric Research or NIWA (Māori: Taihoro Nukurangi), is a Crown Research Institute of New Zealand. Established in 1992, NIWA conducts research across a broad range of disciplines in the environmental sciences. It also maintains nationally and, in some cases, internationally important environmental monitoring networks, databases, and collections. As of 2019, NIWA had 697 staff spread across 14 sites in New Zealand and one in Perth, Australia. Its head office is in Auckland, with regional offices in Hamilton, Wellington, Christchurch, Nelson, and Lauder (Central Otago). It also has small field teams, focused mostly on hydrology, stationed in Bream Bay, Lake Tekapo, Rotorua, Napier, Whanganui, Greymouth, Alexandra, and Dunedin. NIWA maintains a fleet of about 30 vessels for freshwater, marine, and atmospheric research. On 1 July 2025 NIWA became Earth Science New Zealand in a merger with GNS Science, and is considered as a Public Research Organisation.

History NIWA was formed as a stand-alone organisation in 1992 as part of a government initiative to restructure the New Zealand science sector. It was previously part of the Meteorological Service of the Ministry of Transport but was separated into a Crown entity focusing on long-term weather patterns and climate change. Its foundation staff came mainly from the former Department of Scientific and Industrial Research (DSIR) and the Meteorological Service of the Ministry of Transport. One of the DSIR divisions absorbed was the N.Z. Oceanographic Institute. The Fisheries Research Division of the former Ministry of Agriculture and Fisheries joined NIWA in 1995. NIWA is currently structured as a limited liability company under the Crown Research Institutes Act 1992 Most of NIWA's revenue is from contestable research funding and commercial consultancy work. As of 2014, NIWA had a revenue of $123.8 million and assets of $103.6 million. On 26 September 2024, the Minister of Science, Innovation and Technology, Judith Collins, announced that NIWA would be acquiring the MetService. On 14 May 2025, the Minister of Science, Innovation and Technology, Shane Reti, confirmed that NIWA would be integrated into a new Public Research Organisation called the New Zealand Institute for Earth Science.

Mission statement "NIWA's mission is to conduct leading environmental science to enable the sustainable management of natural resources for New Zealand and the planet."

Research

Research programmes NIWA focuses on atmospheric, marine, and freshwater research – extending from the deep ocean to the upper atmosphere – in New Zealand, the Pacific, Southern Ocean, and Antarctica. NIWA's research spans diverse fields:

Research projects are undertaken in collaboration with local and central government agencies, other Crown Research Institutes, industry, private research companies, and universities in New Zealand and the rest of the world. In 2007–08, NIWA scientists were involved in more than 970 collaborations and NIWA had formal links with some 150 overseas institutions. Within New Zealand, NIWA has close working relationships with many Māori entities (85 entities in 2007-08) through its Māori environmental research group, Te Kūwaha o Taihoro Nukurangi. NIWA set up the Te Kūwaha – Māori Environmental Research group to develop ways of sharing knowledge with Māori communities and empowering Māori business with the latest science. This is a critical part of science in Aotearoa New Zealand as institutes have been criticised for poor representation for Māori and Pasifika researchers. The team have had notable success with a taonga species guide and Māori specific climate impact research.

People Past and present staff include:

Awards In 2007, 12 NIWA climate scientists – Greg Bodeker, Matt Dunn, Rod Henderson, Darren King, Keith Lassey, Dave Lowe, Brett Mullan, Kath O'Shaughnessy, Guy Penny, James Renwick, Jim Salinger and David Wratt – shared the Nobel Peace Prize with other contributors to the Intergovernmental Panel on Climate Change.

Research facilities NIWA's research facilities include:

A gas laboratory which uses gas chromatography and mass spectrometry to assess the composition of gases and their isotopes in samples of air and water, and isotope analysis of solid material. An ecotoxicology laboratory for assessing the effects of contaminants – such as heavy metals, pesticides, and wastes – on aquatic organisms. Aquaculture research facilities at Bream Bay in Northland and at Mahanga Bay, Wellington. An upper atmosphere research laboratory located at Lauder, Central Otago, New Zealand. Additionally, NIWA also operates (in conjunction with Antarctica New Zealand) a suite of atmospheric in situ and remote sensing instruments at Arrival Heights, Ross Island, Antarctica.

Lauder Atmospheric Research Laboratory

The NIWA Lauder Atmospheric Research Laboratory takes atmospheric measurements for the purpose of observing and better understanding interactions between the stratosphere, troposphere and global climate. This is achieved through measurements of ozone, solar radiation, aerosols and greenhouse gases. There are approximately 10 staff (scientists and technicians) working at the Laboratory (December 2015).

Location Lauder is located 33 km north-east of Alexandra, in the South Island of New Zealand. It also hosts a telescope part of the BOOTES network. This location was chosen for the laboratory due to the area's low horizons, clear skies, dry atmosphere, and southern latitude location.

Worked examples

Example 1 — a first encounter with National Institute of Water and Atmospheric Research

Start with the simplest possible case. Write down what National Institute of Water and Atmospheric Research claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Institute of Water and Atmospheric Research before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Institute of Water and Atmospheric Research ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Institute of Water and Atmospheric Research

In research: National Institute of Water and Atmospheric Research appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses National Institute of Water and Atmospheric Research in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: National Institute of Water and Atmospheric Research is common in secondary-school and first-year university syllabi. It links to neighbouring topics Environmental organisations based in New Zealand, Governmental hydrological agencies, Science and technology in New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for National Institute of Water and Atmospheric Research outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
