Floods

Floods are New Zealand’s number one hazard in terms of frequency, losses and declared civil defence emergencies. Learn what to do before, during and after a flood to minimise risk to you and your family.

For general readiness, every household should create and practice a Household Emergency Plan and assemble and maintain Emergency Survival Items and a Getaway Kit. In addition, every household should take flood specific precautions and plan for and practice what to do if the flood occurs.

More about floods

Floods are usually the result of continuous heavy rain and/or thunderstorms, but may also be caused by tsunami and coastal-storm inundation. A flash flood often appears as a torrent, can carry rocks, mud, and other debris and can sweep away most things in its path.

Learn about your community’s risks from hazards created by flooding.  Contact your local council to find out if you live in an area prone to flooding.
