He said a separate investigation team had been set up to make inquiries about the fire.Nicholls also said police did not believe Mr Arahanga's death was a result of gang tensions and called for calm from residents.
"What we are dealing with is a single, very serious incident that has cost someone his life and now what appears to be a retaliatory suspicious fire.
"We would ask again that people make the police aware of any information they have on what occurred, not listen to rumours and speculation, and allow the investigation teams to carry out their enquiries."
Detective Inspector Peter Devoy said it appeared the shooting happened after Mr Arahanga had got into a disagreement with some people when at the Hedley St address.
When he left that property a car approached him and a group of other people outside the McGowan St house and someone from the car fired a volley of shots, a "number of which struck" Mr Arahanga."Driving off, the car has then returned to the McGowan St address a very short time later, pulled up and fired a second volley of shots. No one was injured in this second volley."
