Emergency Announcement

If a tsunami has been generated, the first wave may arrive in New Zealand in the areas around Chatham Islands at around midnight on 17 September 2015. The first wave may arrive later and may not be the largest.  Waves may continue for several hours.

People in coastal areas should:

1. Stay off beaches
2. Stay out of the water (sea, rivers and estuaries, including boating activities)
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 your local Civil Defence authorities.

This warning has been issued to all local civil defence authorities, emergency services, other agencies and media.

National Warning: Tsunami Marine and Beach Threat

No:  01

Issued at 12:00 hours on 17 September 2015.

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)
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 

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 local radio stations.

More Detail

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.  

Note:

  • 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. Also see www.civildefence.govt.nz
