Tsunami activity – expect strong and unusual currents
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.

the unusual wave activity as there may be dangerous and

authorities and follow any instructions.
