Tsunami 2024

A tsunami is a series of waves caused by large earthquakes. All of New Zealand’s coast line is at risk of tsunami. A tsunami ocean wave can grow to become a fast moving wall of water.

If you are near the coast or in a tsunami zone and experience any of the following:

• An earthquake which makes it's hard to stand up.
• The earthquake lasts a minute or more.
• Sudden rise or fall in sea level.
• Loud and unusual noises from the sea.

Move immediately to the nearest high ground, or as far inland as you can. Walk or bike if possible.

Do not wait for official warnings.

Tsunamis can arrive in minutes. Often there is no time for an official warning. 

Note: There may be more than one wave, each potentially bigger than the one preceding it. It may not be safe to be near the coast for up to 24 hours.
