Weather hazards

HIRDS is a simple online tool that can estimate the magnitude and frequency of high intensity rainfall at any point in New Zealand.

NIWA-led research

Decisions about how we adapt to sea-level rise need to be based on information about our exposure to coastal flooding.

NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.

The My Coastal Futures game was developed to help people understand climate change impacts and start thinking about how they might adapt.

NIWA and the Ministry for Primary Industries (MPI) are working together to develop a new drought forecasting tool.

RiskScape is a software application for analysing natural hazard consequences.

This five-year NIWA-led research programme is developing a system to map flood hazard consistently across the whole country. It will reveal how our flood risk might change over the next 100 years because of changes to rainfall and sea level from climate change, as well as due to land-use changes. Find out more.

NIWA’s research into forecasting weather systems aims to increase the resilience of New Zealand communities to weather-related hazards.

NIWA is using updated climate projections to help New Zealanders better understand climate-related risks.
