Tsunami sirens in Northland, Auckland and Christchurch were tested on Sunday morning.
Sirens were sounded at coastal and harbour locations around New Zealand from just after 9am in a bid to test the effectiveness of the system.
Along with the sirens Civil Defence also tested their Facebook, twitter and electronic warning systems.
Civil Defence Controller Clive Manley said that it is important people know what the sirens sound like and how they should respond.
The sirens’ sound varies in different parts of the country. In Auckland, coastal residents will hear a short siren first, which warns of an event, and a second tells people to get to higher ground.
Mr Manley said people should use the opportunity to think about what they would do if it was a real event.
