Police will carry out a scene examination with Fire Safety investigators at a West Auckland flat where a man died tonight.
The man has not yet been named.
"It is not known at this stage whether his death was a direct result of the fire or whether another factor such as a fall or medical condition has caused it," police said in a statement tonight.
A young boy and a man aged in his twenties were both taken to Waitakere Hospital in a moderate condition.
The scene will be guarded overnight and when there is sufficient daylight, Waitakere CIB officers will conduct a scene examination with the Fire Service.
