Detective Sergeant Smith said a scene guard was in place overnight and the occupants of six of the eight flats in the building had been found alternative accommodation.
"The priorities for the inquiry team today are speaking to witnesses and completing the scene examination which will be assisted by the arrival of forensic experts from Auckland."
Detective Sergeant Smith said the family of the victim has been informed and carried out a blessing at the murder scene overnight.
The man's body remained at the site overnight and a post-mortem examination will be carried out once it is removed.
