National Tsunami Advisory and Warning Plan

Supporting Plan [SP 01/20] (revised June 2020)

New Zealand is a member of the Pacific Tsunami Warning System (an international system under the auspices of the Intergovernmental Oceanographic Commission of UNESCO) designed to provide timely and effective information and warnings about tsunami generated in the Pacific Basin. In New Zealand the system is complemented by GNS Science/GeoNet geological hazards and sea level monitoring. The National Emergency Management Agency is the agency responsible for disseminating national tsunami advisories and warnings to the communities of New Zealand.

This plan outlines the national procedures used by the Agency to advise local authorities, national agencies and the media of possible tsunami that could affect coastal areas of New Zealand.


Note: The June 2020 version replaces the October 2018 version.
