Reference excerpt

Meteorological Service of New Zealand Limited, doing business as MetService (Māori: Te Ratonga Tirorangi, lit. 'sky-looking service'), is the national meteorological service of New Zealand. MetService was established as a state-owned enterprise in 1992. It employs about 300 staff, and its headquarters are in Wellington, New Zealand. Prior to becoming a state-owned enterprise, New Zealand's national meteorological service has existed in a number of forms since the appointment of the country's first Director of Meteorological Stations in August 1861. As New Zealand's national meteorological service, MetService produces and issues forecasts and official weather warnings on behalf of New Zealand's Ministry of Transport and is certified by the Civil Aviation Authority of New Zealand. International media, aviation and energy business is conducted under the MetraWeather brand. MetService has been certified to the ISO 9001 standard since November 1995. From 1 July 2025 MetService will become a subsidiary of NIWA, which will be part of the new New Zealand Institute for Earth Science.

History The weather forecasting service began in 1861, when a spate of shipwrecks prompted the Government to start a storm warning service as part of the then Marine Department. Forecasting remained a marine service until 1926, when it became part of the newly formed Department of Scientific and Industrial Research. In 1927 Edward Kidson was appointed Dominion Meteorologist by Earnest Marsden. At the time the New Zealand Meteorological Service was a very small institution with a staff of five and a complete lack of useful long-period meteorological records. At the outbreak of World War Two in 1939, forecasting became part of the Royal New Zealand Air Force. The focus on aviation continued with a move in 1964 to the then Department of Civil Aviation, which in 1968 became part of a new "super ministry", the Ministry of Transport. During the 1980s there was increasing pressure on government funding for meteorology in New Zealand, together with a government-wide move to "user-pays" for specialised services, and to more autonomy and accountability for government departments. A combination of commercial competition in the deregulated market for meteorological services and reform of publicly funded science led to the establishment of MetService as a state-owned enterprise on 1 July 1992. In 2013, MetService invested in a 49% shareholding in MetOcean Solutions Limited, a New Zealand oceanographic services company. MetOcean was an established company specialising in oceanographic analysis for research and forecasting for many purposes, including ports, offshore oil & gas industries and surfers. In early September 2020, MetService's website came under a wave of distributed denial of service attacks that also targeted the New Zealand Exchange, Stuff, Radio New Zealand and Westpac bank.

Relationship with NIWA In 1992, the National Institute of Water and Atmospheric Research (NIWA) was spun off from the MetService to become a separate Crown entity focusing on long-term weather patterns and climate change. Following the separation of the two organisations, MetService remained the official weather forecasting authority. Over the next 32 years, the two entities clashed over access to books in the old MetService library and the accuracy of their weather reports. In January 2007, the New Zealand Government brought a mediator to repair relations between the MetService and NIWA. In 2009, the two organisations signed a memorandum of understanding to work more closely together. However, the two organisations continued to clash over the accuracy of their weather reports. In 2020, MetService chief executive Peter Lennox told Parliament that they have more weather models and meteorologists and produced more detailed forecast than NIWA. In 2022, MetService objected to the Department of Conservation's purchase of NIWA's forecasts for use in its parks, claiming it was "inappropriate for public service" due to its reliance on automated forecasts without intervention from professional meteorologists. MetService has a contract with the Ministry of Transport to provide weather forecasts. Following several extreme weather events in 2023, the Government commissioned the Sapere research group to explore how the two meteorological services could combine their capabilities. In late September 2024, Science, Innovation and Technology Minister, Judith Collins announced that NIWA would be acquiring MetService in order to streamline weather forecasting services and give easier access to weather information from one source. Metservice issued a statement welcoming the merger, stating "we see this as an opportunity to have a more connected weather forecasting system that allows a better integration between climate science, forecasting, hydrology, and coastal hazards."

NZ Institute for Earth Science On 14 May 2024, Minister of Science, Innovation and Technology Shane Reti announced that the MetService and NIWA would be integrated into a new Public Research Organisation called the New Zealand Institute for Earth Science.

Overview

World Meteorological Organization The world's national meteorological and hydrological services work with the World Meteorological Organization (WMO), a specialised agency of the United Nations. As part of the WMO World Weather Watch, MetService sends observational data gathered from the New Zealand region to other WMO member countries around the world. This is used as input to computer models of the weather at the world's major numerical weather prediction centres. MetService operates a data collection network within New Zealand. It complies with recognised international standards as prescribed by the WMO over and around New Zealand. In particular, data are collected through:

Surface observations over New Zealand Upper air observations using a variety of means ground-based equipment, aircraft, weather radars Voluntary observing ships A network of drifting buoys in the Tasman Sea. Norm Henry, General Manager of Science and Strategy, is the current permanent representative of New Zealand with the WMO.

MetraWeather MetraWeather (Australia) Pty Ltd, MetraWeather (UK) Ltd and MetraWeather‌ (Thailand)‌ Ltd are wholly owned subsidiaries of Meteorological Service of New Zealand Limited, providing weather intelligence and information presentation products and services globally under the MetraWeather brand to:

Worked examples

Example 1 — a first encounter with MetService

Start with the simplest possible case. Write down what MetService claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 MetService 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 MetService 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 MetService

In research: MetService appears in earth 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 MetService 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: MetService is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1992 establishments in New Zealand, Climate of New Zealand, Government-owned companies of New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for MetService 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.
