Police are yet to find the weapon that was used in the fatal stabbing of 24-year-old Nathan Pukeroa in Mt Albert last week.
The attacker remains on the loose and police are yet to determine his identity.
Mr Pukeroa died in the early hours of Thursday morning on the street outside a home he was visiting on Renton Rd - in a residential pocket of the central Auckland suburb, lined with feijoa trees and home to families who were shocked by what had happened.
But one neighbour described the address outside which the two men were stabbed as a "Mecca of trouble".
A second man, 22, was seriously injured by the same attacker and police believe all parties were known to each other.
