Flood

Latest news

New NIWA-led research shows increasing flood risk is going to be what leads people to make changes to adapt to sea-level rise.
Flood flows on the Buller River this month were the largest of any river in Aotearoa New Zealand in almost 100 years, NIWA measurements show.
Preliminary analysis by NIWA climate scientists has shown that the recent Canterbury rainfall was so extreme in some inland places that it could be expected to happen only once every 200 years.
The prodigious rainmaker that hit Canterbury earlier this month saw NIWA field teams out in the elements collecting flood data from bridges, cableways and jetboat gaugings.

Our work

Flooding is one of the most costly natural hazards in Aotearoa New Zealand. Our regular flood clean-up bills are topped only by much less frequent earthquakes.

A little can mean a lot – especially when it comes to the relationship between sea level rise and coastal flooding.
Two reports released today by NIWA and the Deep South National Science Challenge reveal new information about how many New Zealanders, how many buildings and how much infrastructure could be affected by extreme river and coastal flooding from storms and sea-level rise.
EQC, GNS Science and NIWA have joined forces to further develop world-leading natural hazards risk modelling for New Zealand.
NIWA has completed a project that aims to help build community resilience against flooding in the Bumbu River and contribute to improving Papua New Guinea’s disaster preparedness in the face of increasing climate-related disasters.
