The National Emergency Management Agency (NEMA) have cancelled a ‘National Advisory – Tsunami Activity’ following a large volcanic eruption at Hunga Tonga - Hunga Ha’apai in Tonga on Saturday 15 January 2022.

The eruption caused waves that were noticeable on several coastal tide gauges along the New Zealand coast.

Strong and unusual currents and unpredictable surges will continue for up to another 24 hours in some locations around the entire country. The National Emergency Management Agency (NEMA) is advising people to remain vigilant and take extra precautions with regards to beach and ocean activities.

Only messages issued by the National Emergency Management Agency represent an official warning status for New Zealand. We will provide further updates here in accordance with NEMA.

The largest eruption at the volcano occurred yesterday late afternoon (15 January 2022) and it still seems to be ongoing at lower levels.

If you are reading this from Tonga - follow the Tongan Government's advice.

Remember, Long or Strong, Get Gone.

Drop, Cover and Hold during the shaking. Protect yourself from the earthquake first.

As soon as the shaking stops, move immediately to the nearest high ground, out of all tsunami evacuation zones, or as far inland as possible.

NEMA (National Emergency Management Agency) have a great website with information on what to do before, during and after a tsunami. There you can also find tsunami evacuation zone maps for around New Zealand, and what supplies you need in an emergency.
