Tsunami Activity Advisory - Wednesday 30 July @ 3:50pm

We are not currently expecting massive waves or threat to flooding on land. However, strong currents and tidal surges may take place in coastal areas.

Areas under threat:

All coastal areas of the North Island (including Himatangi and Tangimoana), Great Barrier Island, the South Island, Stewart Island and the Chatham Islands.

There is no need to evacuate other areas unless directly advised by local civil defence authorities.

Strong currents and surges can injure and drown people. There is a danger to swimmers, surfers, people fishing, and anyone in or near the water close to shore.

Advice for people in coastal areas:

• People on boats, live-aboards and at marinas should leave their boats/vessels and move onto shore.
• Move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.
• Do not go to the coast to swim or watch the unusual wave activity as there may be dangerous and unpredictable surges.
• Listen to local civil defence authorities and follow any instructions.
• Share this information with family, neighbours and friends.

We are actively monitoring the situation and we'll provide updates as we get more information.
