Tsunami sirens get test blast

Auckland's tsunami sirens will sound this weekend as the system gets a routine check.

Civil Defence and Emergency Management director Clive Manley said the sirens, which are on more than a dozen sites along Auckland's east and west coasts and in the Waitemata Harbour, would go off at noon on Sunday.

"The public should not be alarmed and are not required to do anything," he said.

The test will involve the sirens sounding three sets of tones, each set lasting for one minute, with 15 seconds between each set.
