More than 25,000 people in Hawke's Bay practiced their earthquake drills and tsunami hīkoi on Thursday.
There were 140 businesses, 160 schools, and 340 households in the region signed up for ShakeOut, Hawke's Bay Civil Defence Emergency Management Group community engagement team leader Jae Whelan said.
"That's a great effort, and we'd like to thank the citizens, schools, organisations and businesses throughout the region who took the opportunity to get on board with this important kaupapa," Whelan said.
She said Hawke's Bay is one of the country's most seismically active regions.
