Police have launched a homicide investigation following the death of a man who was dropped off at the Whangarei St John Ambulance Station this morning.
Northland police say they were called to the ambulance station at around 6.40am and were informed by ambulance staff that the man was critically ill.
He died shortly afterwards.
Detective Inspector Kevin Burke says police are still working to establish the circumstances surrounding the 37-year-old's death.
Mr Burke says police have now identified two "addresses of interest" - one in central Whangarei and another north of Whangarei.
ESR staff have arrived from Auckland and will be carrying out scene examinations at both addresses and also at the Whangarei St John Ambulance Station, he said.
Police will not be releasing the victim’s name until formal identification has taken place, he added.
A post mortem will be carried out tomorrow and inquiries were underway to identify the man.
1 News understands the incident was gang related.
A cordon has been set up at the ambulance station but police say the incident will not affect the station's operation.
