Air Raid Siren???
In New Zealand, the local warning signal for a civil defense emergency is a continuous siren, like that on a police car. If you hear this, you should listen to your local radio station to learn what the emergency is and what to do. In the small towns around New Zealand, the local fire departments are run by volunteers, so when there is an emergency, the Volunteer Firemen are summoned by the Civil Defence Siren (Air Raid Siren) so do not worry, New Zealand is not being bombed!
However in the unlikely event, you should hear one in a larger centre, then it is either a Test or an actual Emergency is Imminent or has already occurred. Our advice is for you to seek advice from a local as soon as you can. In an emergency, the siren would sound if there was a Severe Weather Warning with Expected Flooding or Extreme Winds or an Earthquake and Expected Tsunami. The siren indicates that important information is about to be broadcast on the local radio stations. What should you do in this situation? - Don't panic - Stay indoors (the only action you should take is turn on a radio) Follow the instructions which are broadcast - Stay clam - Keep listening for further information. The civil defense alerting signal is similar in sound to a volunteer fire station siren, however, the civil defense signal will rise and fall several times each minute for five minutes or longer if required.
