Bay of Plenty Civil Defence - Tsunami marine and beach threat update

Thursday, 17 September 2015 5:30 p.m.

Bay of Plenty Civil Defence is urging people in coastal areas of the Bay of Plenty to keep away from beaches, coastal areas and river mouths in the coming 24 hours.

The Ministry of Civil Defence & Emergency Management (MCDEM) has issued a tsunami warning (marine and beach threat) for Chatham Islands and the East Coast of New Zealand. Wave heights of between 0.2-1 metre can be expected for much of the East Coast of New Zealand (see attached map) and Chatham Islands.

People in the affected coastal areas should:

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

The first tsunami activity may reach the East Cape at approximately 1.21am on 18 September 2015. It is expected to bring unusually strong currents and unpredictable water flows near the shore. Current assessments indicate that coastal inundation (flooding of land areas near the shore) is not expected, but this assessment may change.

Bay of Plenty Civil Defence Group Controller Clinton Naude said that it’s likely there will be tidal surges and unsettled seas tonight and throughout the day tomorrow.

“We recommend that people stay out of the water and away from coastal areas. Whitebaiters should take extra care too – they may not be fishing on the coast but tidal surges could create unusual currents and rising water levels in the lower reaches of our local waterways," Mr Naude said.

The tsunami warning will remain in effect until a cancellation message is issued by MCDEM.

Regular updates will be provided on Bay of Plenty Civil Defence Emergency Management’s website and on

As the situation evolves, more information will be available.  A list of relevant radio frequencies and websites are listed at the end of this release.
