Auckland Emergency Management (AEM) will be testing the region’s tsunami siren network around midday Sunday 3 April, Auckland Council says. The scheduled six-monthly siren test will sound at noon, but with one important change; it will be a combination of alert sounds and voice instructions advising what actions residents should take. “It’s important to test the sirens to make sure they’re working and to remind Aucklanders what they sound like. There’s no cause for alarm during the testing and no action is required by the public,” Auckland Emergency Management’s General Manager Paul Amaral says.
