NZ Proposes Integration of NIWA and MetService to Enhance Weather Forecasting System

The proposal, which has been agreed to in principle, would see NIWA acquire MetService, while MetService would retain its role as New Zealand’s authorized meteorologist.

The New Zealand Government is exploring the integration of the National Institute of Water and Atmospheric Research (NIWA) and MetService to enhance the country’s weather forecasting capabilities, according to Science, Innovation, and Technology Minister Judith Collins.

The proposal, which has been agreed to in principle, would see NIWA acquire MetService, while MetService would retain its role as New Zealand’s authorized meteorologist. The integration aims to streamline weather forecasting by combining expertise in atmospheric, land, and hydrological sciences with the daily public weather updates currently provided by MetService.

“Having a strong weather forecasting system that combines these scientific disciplines will help us meet current and future demands of New Zealanders,” said Collins.

Importance of a Unified Weather System

The proposal comes in the wake of severe weather events in 2023 that resulted in significant economic losses—an estimated $12 billion overall and $5 billion in insured losses. These tragedies highlighted the need for a more robust and integrated weather forecasting system capable of predicting extreme events more accurately.

"Our weather forecasting system is critically important, not only for public safety but also for the aviation, marine, and energy industries, as well as many other businesses across New Zealand," Collins emphasized. By streamlining the system, the Government aims to provide easier access to trusted weather information from a single source, enhancing both safety and operational efficiency.

Benefits of Integration

The Government's Weather Forecasting System Review found a compelling case for change, suggesting that integrating the scientific expertise of NIWA with MetService's public meteorological services would allow for a more comprehensive understanding of climate, weather forecasting, hydrology, and coastal hazards. This unified approach is expected to improve New Zealand's preparedness and response to extreme weather events.

“By bringing together the science around climate and hydrology with daily weather forecasting, we can improve our ability to respond to severe weather events and enhance safety for all New Zealanders,” Collins added.

Next Steps Toward Implementation

While the proposal has received initial support, Collins acknowledged that further work is required before the integration can proceed. Officials from the Treasury and the Ministry of Business, Innovation and Employment have been tasked with collaborating with NIWA and MetService to outline the specific details of the implementation process.

“A more streamlined system will increase safety, improve efficiencies, and support a future-focused weather forecasting system that works for all New Zealanders,” Collins concluded. The Government is expected to release further updates as the integration plan progresses.
