A 25-year-old man who died in Whanganui on Tuesday night has been named as Yusef Zurich.
Mr Zurich was driven to Whanganui Hospital following a disturbance at a house in the suburb of Gonville, where about 15 people had been socialising.
He died soon after arriving at the hospital.
Police say post-mortem results show Mr Zurich died of a severe wound to his arm.
The police are continuing to interview neighbours and those who were at the house at the time, while a scene examination will continue for one or two more days.
They are also interested in the movements of a red Ford Telstar car, believed to be the vehicle that Mr Zurich was taken to the hospital in.
