Police say a fatal attack on a teenage boy outside his home in the South Auckland suburb of Weymouth was not random.
A postmortem shows John Xavier Andrew Hapeta, aged 14, (known to his family as "John John") died from a blow to the head on Tuesday night. A handgun and a hammer were used.
Detective Inspector John Tims told Morning Report there was a reason and a motive for them to come to the address. They arrived with their faces partially covered.
Descriptions have been issued of two men seen running from the scene. Both are Maori who were wearing black hoodies.
One is described as tall while the other, thought to be between 18 and 20 years of age, is of stocky build.
Police will look into whether the attack has any gang or drug connections.
Detective Inspector John Tims says they will be talking to the dead boy's friends and family in order to get a clearer picture of what he was really like.
The incident in Weymouth was the latest in a series of killings in South Auckland:
