Support services are being wrapped around the family of those killed in the Palmerston North house fire.

A six-year-old girl and her grandmother died in the blaze in a Housing New Zealand house in Takaro early yesterday morning.

The remaining nine family members are recovering from a range of injuries.

Fire and police investigators hope to get inside the house today to conduct a more detailed scene examination.

Detective Inspector Ross McKay said victim support services are helping the family, and the family's school communities are also being supported.

The Housing New Zealand property had smoke alarms reinstalled less than a year ago. Eleven were installed throughout the two storey home - which was due to be inspected again this November.
