The female, who was one of the two occupants, was inside the two-bedroom house that was completely destroyed by the blaze. She escaped uninjured after she was alerted to the fire that broke out at about 11pm.
Teimurimotia Fire Station received the call to attend the fire from Rescue Fire Services at 11.34pm.
Chief station officer Alistair Macquarie said the Rescue Fire was unable to attend because of an incoming flight.
Five fire trucks – three from Teimurimotia and two from Puaikura – and about 16 volunteer firefighters arrived at the scene 15-20 minutes later.
Macquarie said access to the property on the hillside was blocked by a car which was parked on the driveway.
He said they also had to get water 100 metres up the hill.
The house was engulfed in fire with flames breaking out of the window when the firefighters arrived at the scene.
Macquarie said it took them about an hour to contain the fire.
Rescue Fire Services is expected to carry out an investigation on the cause of the fire today.
