New Zealand has just over 50 native freshwater fish species. Of these, 85 % are endemic and 75 % are deemed to be at risk of decline or are threatened.

The annual end-of-summer snowline survey of more than 50 South Island glaciers has revealed continued loss of snow and ice. Last week, scientists from NIWA, Victoria University of Wellington, and Department of Conservation took thousands of aerial photographs of glaciers. Some of them are used to build 3D models that track ice volume changes.

New research from the Deep South Challenge: Changing with our Climate and NIWA shows that New Zealand could experience very long and “very severe” marine heatwaves by the end of the century.

A robot sea craft is the latest tool NIWA scientists are using to help them count fish.

The tempestuous wet weather may have dampened Wellingtonians' spirits at the beginning of summer, but it had at least one positive effect - killing some unwanted species in the harbour.

Coastal sea temperatures around Aotearoa New Zealand have risen well above average, NIWA forecasters say.

One of the best ways to reduce the likelihood of Covid-19 being transmitted in Aotearoa New Zealand classrooms is simply by opening doors and windows to create natural ventilation, say NIWA air quality experts.

New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.

A project is under way to determine whether Aotearoa New Zealand’s long defunct rock oyster industry can be revived.

Aotearoa New Zealand has just experienced its warmest winter on record – well exceeding the previous record which was set just last year.
