Neighbours of a Hamilton house on fire woke the sleeping family in time to escape with their lives.
There were no smoke alarms in the two-storey Nixon St house when the blaze took hold about midnight.
The upper level - which was on fire - was empty after its previous tenant had been evicted, neighbours told the Herald.
The top level has been left gutted while a window remains smashed in the lower level unit with other debris scattered around the driveway.
A neighbour said the fire was so intense that she thought the house directly beside the blazing building was on fire.
