Police are appealing to anyone in the Renton Road area of Mt Albert who may have witnessed or know anything about an attack which ended the life of Nathan Mata Pukeroa to come forward.
24 year old Pukeroa was assaulted outside a Renton Road address in the early hours of the morning on Thursday December 3.
A 22 year old friend of Pukeroa was also assaulted by the same person who is yet to be identified.
Detective Inspector Chris Cahill says the key to solving the mystery of who killed Nathan Pukeroa and nearly killed his friend, could lie with the Renton Rd neighbourhood.
"We'd like to hear from anyone in and around the Renton Rd vicinity who has noticed any suspicious behaviour in the area over the past several weeks.
"We are also urging residents in the area to search their properties and advise us if they find any sharp instrument that could have been used as a weapon and that has been discarded by the person or people responsible.
"One focus of the team today is on tracking the movements of a red Toyota utility that left the Renton Rd address shortly after the fatal attack that occurred at about 12.15am on Thursday, December 3.
"We need to hear from anyone who saw it in the vicinity at around about the same time Nathan was killed or anywhere in the upper North Island in the four days since."
Mr Cahill said it was important people remember that a young man died outside a home in a suburban street and another was seriously injured and that the killer has not been identified or located.
Nathan Mata Pukeroa will be buried at Ohaki Marae in Pawarenga, today.
