Tsunami Warning Issued For Pegasus Bay

UPDATE as off Saturday 9 September 12:00 PM: The tsunami warning for Pegasus Bay has now been cancelled. Thank you for your cooperation in staying clear of our beaches. Enjoy the rest of your weekends.


Update: Saturday 9 September 8.33am

The Ministry for Civil Defence and Emergency Management has updated the tsunami warning this morning. It remains the same as the warning issued last night, namely a marine threat exists with unpredictable surges and hazardous currents. The public are urged to stay away from river mouths, particularly the Waimakariri River mouth and estuaries. Civil Defence staff are currently patrolling the Waimakariri River mouth up to the Ashley River and estuary. No evacuations are necessary.

A tsunami warning has been issued for some coastal parts of New Zealand, including Christchurch and Banks Peninsula, following the magnitude 8.1 earthquake that hit the southern coast of Mexico. The Ministry of Civil Defence and Emergency Management (MCDEM) is advising that a beach and marine threat exists for Pegasus Bay, the northern coasts of Hawkes Bay and East Cape, and the Chatham Islands.

Unusually strong and hazardous currents and unpredictable surges are expected near beaches in harbours and estuaries. The severity of currents and surges will vary within a particular coastal area and over the period the warning is in effect. Please note there is NO threat to land and no evacuations are necessary.

Current assessments indicate that coastal inundation (flooding of land areas near the shore) is not expected but that assessment might change.

The first tsunami activity is expected to reach the areas around Chatham Islands and East Cape about 7am Saturday. This may be later and the first activity may not be the most significant. Strong currents and surges will continue for up to 24 hours and MCDEM says the tsunami threat must be regarded as real until this warning is cancelled.

People in coastal areas should:

  • Stay out of the water (sea, rivers and estuaries). 
  • 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.
