This message is current and replaces all/any previous messages for this event.
GNS Science has advised that the largest waves have now passed, and therefore the threat level is now downgraded to a Beach and Marine threat for all areas which were previously under Land and Marine threat.
All people who evacuated can now return.
The advice remains, for all areas under Beach and Marine threat, to stay off beach and shore areas.

Strong and unusual currents and unpredictable surges will continue for several hours and the threat must be regarded as real until this Advisory is cancelled.
