Two people involved in a homicide in Auckland's Flat Bush are believed to be linked to the Hells Angels gang.
The Herald understands the alleged offender is a Hells Angels gang member while the victim was a prospect.
The investigation was launched after a man was found dead at Bezar Pl property from which gunshots had earlier been heard.
Counties Manukau District criminal investigations manager Detective Inspector Fa'amanuia Va'aelua said the man's body was found at the property after police negotiated with a 38-year-old man over several hours to exit the house.
Police first received a 111 call from a resident about 1.15am, saying they could hear a person in distress at a nearby home, followed by gunshots.
Armed Offenders Squad members went inside through a window and safely brought out several occupants, including a child.
After hours of engagement, the man surrendered and was taken into custody.
