The power of the earthquake’s tremors knocked food items from their shelves in the stores and set off alarms.

Locals reported that the temblor lasted longer than usual, forcing houses to creak, which caused some people to panic.

GNS Science spokeswoman Caroline Little said the quake was labelled as “strong.”

“We've classed it as a strong quake so a small amount of structural damage, but more likely things falling off shelves and that sort of thing,” she said.

Little warned that some aftershocks are to be expected.

“The general rule of thumb with aftershocks is they'll be up to one magnitude less than the main shock, so we might have some fives and fours and threes as well,” she said.

Kaikoura’s store manager, James Hills, described the chaos in his shop after the quake hit.

“Fair bit of panic - get out of the shop, everything was falling off the shelves. There's been a little bit of damage, certainly not heaps, but yeah, there's a lot of stuff fallen over.”

“Well, initially, we were up on the second floor and felt a slight movement, we thought, 'that's okay, that's it,' so we just took our seats, then it came on - to me, it was a rolling motion, quite firm, quite solid,” Kaikoura's mayor, Winston Gray, told Radio New Zealand News, adding that there were some reports of minor damage throughout the city.
