Hawke's Bay residents got into the full swing of things for yesterday's national Shake Out drill.
Napier Civil Defence Manager Angela Reade said the exercise had been a huge success, with nearly 47,000 people signed up to "drop, cover, hold" in Hawke's Bay.
All but one of the city's 16 sirens sounded at 9.26am for five minutes. Mrs Reade said the Maraenui siren, which failed to sound, was found to be damaged by vandals.
"It was really disappointing, because the drill itself was a real success," she said.
About 100 schools from Hawke's Bay had signed up, with some taking special precautions to ensure all students participated.
