The bi-annual test of the two tsunami sirens at Ōrewa is scheduled for Sunday 7 April 2024, at midday, coinciding with the end of daylight saving.

“We need to ensure the sirens are working properly. No action is required by the public and there’s no cause for alarm during the testing,” Auckland Emergency Management Acting General Manager Adam Maggs assures.

Located at Ōrewa beach, the sirens provide a combination of alert sounds and voice instructions, guiding residents on necessary actions during a real emergency.

Sample siren sounds are available on the Auckland Emergency Management website.

Ōrewa stands as the sole location in Auckland with functioning tsunami sirens, following the deactivation of sirens at other sites in December 2023 due to vandalism, theft, and outdated technology.

The two sirens at Ōrewa, installed in 2020, are newer and have remained free from such issues.

A new project is underway to explore the most effective methods of warning residents and visitors about tsunami risks in the coastal areas of the region.

Councillor Sharon Stewart, Auckland Council’s Civil Defence and Emergency Management Committee chairperson, underscores the importance of the siren test as a reminder to all Aucklanders of the timely communication in the event of a potential tsunami. “An Emergency Mobile Alert will be broadcast to all capable mobile phones...”

Stewart also urges Aucklanders to utilise Auckland’s Hazard Viewer, a tool displaying updated and simplified tsunami evacuation maps, offering crucial information in times of emergency.

“Our new modelling is more accurate and indicates the tsunami risk for much of the Auckland coastline to be lower than previously expected.”

Natural Signs and Preparedness

Residents near the shore are advised to be vigilant for natural warning signs of a tsunami, including strong or prolonged earthquakes, sudden changes in sea level, and unusual noises from the sea.

In the event of a tsunami threat, it’s crucial to remember: if an earthquake is long or strong, get to higher ground.

Aucklanders are encouraged to prepare household emergency plans and familiarise themselves with evacuation procedures.

Updated tsunami evacuation maps and preparedness tips are available on Auckland’s Hazard Viewer.

The safety and preparedness of residents remain paramount in Auckland’s ongoing efforts to enhance disaster resilience.
