Sat Mar 12 01:13:50 AEDT 2011

Civil Defence says a tsunami is possible but it has issued a marine 
threat advisory only - it does not expect a tsunami to travel inland. 
Instead it is warning of strong and unusual currents and advising people 
to stay off beaches and low-lying coastal areas.

        Estimated wave arrival times:

6:23am North Cape - to coincide with low tide.
7:23am East Cape and Auckland's west coast
7.29am Gisborne
7:45am Milford Sound
7:53am Wellington
8:05am Auckland's east coast.
8:08am New Plymouth.
8:17am Napier
8.37am Westport
9:29am Dunedin
10:03am Lyttelton
10:15am Nelson
10:20am Bluff

Times are estimates only as provided by local authorities. The first 
wave may arrive up to an hour either side of the estimated times and 
waves may continue for some hours.

        People in coastal areas are advised to:

Stay off beaches.
Stay out of the water (sea, rivers and estuaries, including boating 
activities).
Do not go sightseeing.
Share this information with family, neighbours and friends.
Listen to the radio and/or TV for updates.
Follow instructions of your local Civil Defence authorities.

      Local authorities have issued specific warnings and advice.

        Northland

The marine threat means strong and unusual currents are possible in the 
sea, river mouths and estuaries and all Northland coastal residents are 
being warned to stay off beaches.
At 2am Civil Defence said that a minor land threat (1-3 metre wave 
heights) now exists in Northland between Ahipara and the Karikari 
Peninsula as well as in the Bay of Islands and the Chatham Islands.
"We are asking all coastal residents and visitors to stay off the 
beaches, out of the water and not to go sightseeing along our coast," 
says Tony Phipps, Group Controller Northland CDEM Group.
Northlanders are being asked to share this information with family, 
neighbours and friends and to listen to the radio and/or TV for updates.
The first waves are estimated to coincide with low tide on the east 
coast (0625 at Marsden Point).
Low tide on the west coast - at Pouto Point - is 0823.
Tsunami activity, such as unusual currents and changes in sea-level, 
will continue for several hours.

        Auckland

No evacuations are required.
The Harbourmaster has advised that ships do NOT need to leave port but 
all mariners are advised to navigate with caution and have a listening 
watch on VHF channel 16.
Mariners on board their vessels should check its security on Saturday 
morning.
Any beach activities or events planned for Saturday should be postponed
The Waiheke Coastal Classic Fun Run and Walk has been postponed until 
Sunday.
Auckland Civil Defence has issued a tsunami warning for the region's 
coastlines of a tsunami of up to 1m including strong currents and 
disturbed seas and estuaries.

        Tauranga and BOP

There is now a minor land threat (i.e. 1-3m wave heights) existing in 
Northland between Ahipara and the Karikari Peninsula as well as in the 
Bay of Islands and the Chatham Islands.
A marine threat (ie threat to beach, sea and in estuarine areas) remains 
in place for the Bay of Plenty.
The main message for the public right now is to stay away from the 
beaches and waterways - this includes all boating activity.

        Hawke's Bay

The tsunami is not expected to cause any significant waves along Hawkes 
Bay coastline, as it is on the lee side of New Zealand and sheltered 
from waves generated from near Japan. |
Our estimate is for a possible wave run-up of up to 0.5 metres.

        Bay of Plenty

The Whakatane River Bar has been declared unworkable.

        Dunedin

The tsunami is not expected to cause damage to Dunedin.
As the wave is propagating from the north-west of New Zealand, the 
Dunedin coast should be protected from severe effects.
Residents should, however, exercise caution on beaches and estuaries 
from 08:30am on Saturday, as unusual tidal effects could be experienced.

        Southland, Fjordland

Ships and small craft in Southland and Fiordland waters are being warned 
of the tsunammi threat.
There are likely to be strong and unusual currents around the coast, 
including estuaries and the tidal reaches of rivers.
There may be unusual wave activity at beaches and members of the public 
are urged to stay away from beaches around Southland and Fiordland.
Disturbed currents could last for up to 24 hours.
