Currently no evacuation zones are available for less populated areas of Banks Peninsula.
The tsunami evacuation zones are determined by local tsunami and coastal scientists and emergency managers.
Every tsunami is different and most will not flood land, although they can still cause strong currents and water surges. If a tsunami does flood land, the areas affected will be determined by the exact size and direction the tsunami is coming from.
The evacuation zones include these different tsunami scenarios and extends further inland than the worst flooding we would expect to see in a 2,500 year time frame.
As research about earthquakes and tsunamis continues, and further modelling work is developed, it is possible that the zones could change slightly.
If you’re near the sea, and you’re in an earthquake that is strong enough to make it difficult to stand up, or a long rolling earthquake that lasts a minute or more, once the shaking stops head inland or for higher ground.
Keep safe by evacuating when you are advised to. There may not always be a tsunami, but it's better to be safe than sorry.
If you feel it is unsafe for you and/or your family to remain in the area – leave.
Share any official warnings that you are aware of with neighbours, family and friends who are near the coast.
If you are required to evacuate, take the route closest to your home or workplace (follow the direction of emergency services personnel).
