GNS Science and the Tasman District and Nelson City councils have developed a series of tsunami evacuation maps.
- View the Interactive Maps.
- The maps are also available for download.

What the maps show
There are three evacuation zones shown on the maps:
Red Zone
- Small more frequent tsunami that are essentially a beach and nearshore hazard.
- The Red Zone is also the area of greatest impact in a larger tsunami.
Orange Zone
- Large distant source tsunami.
- Due to the relatively long travel time, official warning of such a tsunami approaching can be expected.
Yellow Zone
- Large, but very infrequent, local sourced tsunami.
- Because of the short travel time, it is unlikely that there will be an official warning.
- The public will need to self-evacuate based on natural warnings (see below for what this means).
