"My wife screamed and we each grabbed one of our two children and ran downstairs. She ran outside with our oldest child, and some of our neighbours were outside, scared and alarmed.
"It felt like the house was going to crumble."
Mr Weekes said aftershocks were felt for a number of hours afterwards. "Our family set up blankets downstairs and we tried to get our 3-and-a-half year old and 1-year-old children back to sleep -- huddled all together. We were scared of the violent aftershocks."
Mr Weekes said his town experienced power outages and road closures. Grocery stores were closed due to damage from fallen stock and many of the schools would remain closed for another day.
The local government and community had rallied together to take care of one another "like they would back home" he said. "However, I would like to move to a one-storey house; being on the top level was crazy."
Three travel agencies spoken to by the Bay of Plenty Times said they were yet to get any phone calls from concerned travellers heading to the area.
