The National Institute of Water and Atmospheric Research (NIWA) is a Crown Research Institute (CRI) and New Zealand’s leading supplier of atmospheric, freshwater, environmental and marine science services.
Our purpose is to enhance the economic value and sustainable management of New Zealand's aquatic resources and environments, to provide understanding of climate and the atmosphere and increase resilience to weather and climate hazards to improve the safety and wellbeing of New Zealanders.

We collect, store and manage data on NZ’s weather, climate, marine and freshwater resources and other important environmental parameters. We deliver data via a range of tools and services that help Kiwis manage their interactions with the environment and its resources more productively and sustainably.
