The Ministry of Civil Defence & Emergency Management (MCDEM) has issued a tsunami warning (marine and beach threat) for East Cape, Chatham Islands, Coromandel, and Banks Peninsula.
People in the above coastal
areas should: 1. Stay out of the water (sea, rivers and
estuaries, including boating activities) The tsunami warning will remain in effect
until a cancellation message is issued by MCDEM. Updates
will be issued hourly. Only messages issued by MCDEM
represent the official warning status for New Zealand, not
those issued by the Pacific Tsunami Warning Centre
(PTWC). This warning has been issued to all local civil
defence authorities, emergency services, other agencies and
media. Local civil defence authorities will interpret this
information for their areas and advise public action via
2. Stay off beaches and shore areas
3. Do not go sightseeing
4. Share this information with family, neighbours and friends

Only messages issued by MCDEM represent the official warning status for New Zealand, not those issued by the Pacific Tsunami Warning Centre (PTWC).
This warning has been issued to all local civil defence authorities, emergency services, other agencies and media. Local civil defence authorities will interpret this information for their areas and advise public action via local radio stations.
Areas under ‘Marine and Beach Threat’: 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. Current assessments indicate that coastal inundation (flooding of land areas near the shore) is not expected but this assessment may change.
• The wave amplitudes given
indicate the largest expected wave activity at any coastal
point in the particular coastal zone and at any time during
the entire period this warning is in effect (tsunami
activity will vary in a zone and with time; the first wave
activity may also not be the largest).
• The given amplitudes do not include the local tidal or sea state at the time of tsunami activity.
• Local authorities will determine the implication of the expected wave heights for their areas and will decide on appropriate response actions (e.g. evacuations). Listen or check for this information from your local authority.
The first tsunami activity may reach New Zealand in the areas around East Cape at approximately 00:15 on 18 September 2015. This may be later and the first activity may not be the most significant. Tsunami activity will continue for several hours and the threat must be regarded as real until this warning is cancelled.
This warning has been issued to all local civil defence authorities, emergency services, other agencies and media. MCDEM and scientific advisors are closely monitoring the situation to update this assessment. Information will be updated or repeated at least hourly until this warning is cancelled.
