Public Warning Systems

Find out about sirens and stingers, and our suite of alerting tools including Emergency Mobile Alerts, the Red Cross Hazard App and radio stations.

Sirens and Stingers

Napier has public alerting sirens and the HBCDEM Group has a suite of Stingers that can be used to alert the public. The Civil Defence siren alert is 5 minutes long (10 second on, 20 seconds off – 10 times). These are flick tested occasionally. Stingers are attached to a vehicle and can transmit messages via a megaphone.

If you hear a Civil Defence siren alert or stinger message

Seek further information. Tune it in to a local radio station, check this website and emergency updates, or go to the HBCDEM Facebook page. Follow advice that is given.

Tsunami warning

Sirens and stingers will never be used to warn for a local source tsunami.  The only warning for a local source tsunami is a large earthquake.  If an earthquake is longer than one minute, or could knock you off your feet, immediately evacuate away from the coast. Remember Long or Strong Get Gone.
