If you hear sirens or "stingers" on Sunday, September 24, don't be alarmed, public alert systems are being tested in Napier and in Hastings coastal communities.
Hastings urban (city) "stinger" testing will also take place in Havelock North, Hastings CBD, Mahora, Stortford Lodge and Flaxmere on Thursday, September 21, between noon -1pm.
The 17 sirens in Napier will sound for five minutes from 11.50am on September 24, while Civil Defence volunteers will be driving around Waimarama, Clive, the Cape Kidnappers coast and Whirinaki with "stingers" for about an hour from this time.
It's part of the regular testing regime by the Hawke's Bay Civil Defence Emergency Management Group.
The alert systems are aimed at encouraging people to seek further information, by tuning in to a local radio station and awaiting further instructions, visiting the HBemergency website, or the HBemergency Facebook page.
