Tsunami Evacuation Zones
This page has the tsunami evacuation zone maps.
All of New Zealand is at risk of earthquakes and all of our coastline is at risk of tsunami. We can’t predict when earthquakes and tsunami will happen, but you can help protect yourself and your family by knowing if your property is in a tsunami evacuation zone and what you need to do.
In an earthquake
- Drop, cover, hold – this makes you a smaller target, stops you being knocked over and protects your head, neck and vital organs.
If you are near the coast and in a tsunami zone
- If it’s long or strong be gone – if you feel an earthquake that rolls for more than a minute OR makes it hard to stand up, don’t wait for a tsunami warning as there may not be time for one in your area. Move to high ground or as far inland as you can. Walk if you can. Stay there until you get the all clear.
Find out if you’re in a tsunami zone and make a plan today,
- Know where to go, find out who can help you and who might need your help.

What do the colours mean?
The red zone is the beach and marine environment, and some very low lying areas. This area is the one we ask people to stay out of most often as a result of smaller tsunamis. Evacuate this area when instructed to, or immediately after any long or strong earthquake.
The orange zone is the area we may evacuate for a large earthquake in the Pacific, such as near South America, causing a tsunami wave of up to 5 metres at the Wellington coastline.
The yellow zone is the self-evacuation zone which means if you feel a long or strong earthquake, then get yourself out of all zones. This zone has been defined by modelling up to magnitude 9 earthquakes on the subduction zone to the east of the North Island, the worst case scenario for the Wellington region.
