Police are waiting for the results of a post-mortem on a man who died following a domestic incident in south Auckland overnight to determine if a crime was committed.
Police and ambulance staff found the 44-year-old man dead when they arrived at a Mangere house just before midnight.
Detective Senior Sergeant Dave Lynch, of Counties Manukau CIB, said it appeared the man died during, or shortly after, a fight with a male family member. However it was not known if the fight was the cause of death.
"He was definitely fighting, but we don't know how he died, and if the fighting contributed towards his death. For instance, he might have had a heart attack or some other aliment during the course of the fight," Mr Lynch said.
"We don't actually know if a crime has been committed. Everything depends on the results of the post-mortem to determine how the person died."
Police were not looking for anyone else in relation to the incident, and the family was co-operating with police, Mr Lynch said.
A post-mortem was expected to be carried out later this afternoon.
