Ms Vaughan said the following ambulance stopped and a short time later a third arrived. She noticed three fire appliances and at least five police vehicles. "And then the helicopter landed."
Three St John staff were flown to Whangarei Hospital, one with a suspected broken arm.
Another resident Anthony Dunn said he was woken by the helicopter hovering over his house.
"I didn't hear the crash but when I went out I saw why the helicopter was there. The ambulance had smashed into a pole."
Police had diversions in place so the helicopter landed on State Highway 1 and loaded the three patients.
At 10am power had not been restored and candles were being used for light in the Moerewa Four Square store.
The owner was selling necessities such as milk and bread to the locals and taking cash only as the till and eftpos machine were not operating. Candles flickered in the aisles to help shoppers.
