Police are investigating a suspicious house fire that killed a woman and left two children in serious condition in Hamilton.
Neighbours were woken by the fire in Fairfield about 3.45am as flames engulfed the state house.
Friends of the family said seven people were living at the house including two children taken in when their mother died last year.
A woman, her partner and three teenagers were also believed to live at the house.
Neighbour Rita Didovich said she was woken by her dog barking and as she went out to quieten him down she spotted flames coming from the house.
