Police say the homeless man who died in a fire in an abandoned central Christchurch house did not appear to have been attacked.
A post-mortem carried out on the badly burned body of 62-year-old Terence James Palmer, also known as Terry Baker, showed he probably died of smoke inhalation, police said on Thursday.
Mr Palmer's body was found in the second storey of the house used by homeless people in Peterborough Street on Tuesday night.
Mr Palmer was unemployed and was of no fixed abode, said police, who are not treating his death as suspicious.
"However the investigation is ongoing and we are continuing to interview witnesses. We are not yet in a position to make a final determination on how the fire started," said Detective Sergeant John Gallagher.
