Areas under ‘Marine and Beach Threat’ can expect unusually strong currents and unpredictable water flows near the shore. This means a threat to beach, harbour, estuary and small boat activities. The severity of currents and changing water flows will vary within a particular coastal area and over the period this warning is in effect. The Chatham Islands and the region between Blenheim and Banks Peninsula is still prone to a marine and land threat, and future maximum wave amplitude of approx. 1-3 metres can still possibly be expected to occur.

People in all coastal areas should:

1. Stay out of the water (sea, rivers and estuaries, including boating activities)

2. Stay off beaches and shore areas

3. Do not go sightseeing

4. Share this information with family, neighbours and friends

5. Listen to the radio and/or TV for updates

6. Follow instructions of local civil defence authorities

7. If beach threat is forecasted for your area, take appropriate evasive action
