The initial suspicion was that the blaze had been started by an electrical fault in a water pump under the house, but after talking to the owner, the cause seemed more likely to have been smouldering cigarette butts from ashtrays that she had emptied into a container at the back door.
There was little for firefighters to do, however, apart from ensuring that the fire wasn't going to re-ignite and blowing smoke out of the house.
Meanwhile, a motorbike accident on SH10 at Kaingaroa on Christmas Day took the Kaitaia Fire Brigade to 400 calls for the year, the first time that mark has been reached.
