National Institute of Water and Atmospheric Research

NIWA is New Zealand's National Institute of Water and Atmospheric Research, a Crown Research Institute that conducts scientific research and provides advice on water resources, climate, oceans, atmosphere, and natural hazards. It delivers services such as environmental monitoring, weather forecasting, fisheries research, and freshwater management to central and local government, industry, iwi, and the public. The organisation operates a network of laboratories, field stations, and monitoring sites across the country, enabling it to collect data from diverse ecosystems ranging from alpine rivers to coastal marine environments. NIWA also maintains specialised facilities, including the FitzRoy supercomputer, which supports high‑performance modelling of climate and oceanic processes. Its work informs policy development, risk assessment, and sustainable management of New Zealand’s natural assets.

As a Crown Research Institute, NIWA is wholly owned by the New Zealand government and operates under a mandate to serve the public interest through independent science. It employs a multidisciplinary workforce of scientists, technicians, and support staff who collaborate on national and international research programmes. The institute is recognised for its expertise in atmospheric chemistry, hydrology, marine ecology, and cryospheric science, positioning it as a key advisor on issues such as climate change adaptation and natural hazard preparedness. Notable among its assets is the FitzRoy supercomputer, which was temporarily disconnected from the internet in May 2014 following reports of a suspected cyber intrusion, an event that highlighted the importance of cybersecurity for critical research infrastructure. NIWA continues to provide long‑term datasets and predictive tools that support decision‑making across sectors ranging from energy and agriculture to tourism and disaster response.
