The 27-year-old man who died a "violent death'' in Auckland early on New Year's Day has been identified as Papatoetoe resident Nathan Albert.
A homicide investigation was launched after a woman found Mr Albert's body on the street in Panmure's Pilkington Road shortly after 4am and phoned police.
A post mortem examination concluded he had died a violent death, Detective Inspector Mark Benefield told Radio New Zealand.
Police this evening said a man known to Mr Albert had contacted police, and he was assisting them with the investigation.
"It is too early to say what the outcome of the discussions with this man will be,'' Mr Benefield said.
