The critically injured man who was shot at a Harley Davidson dealership in Auckland is thought to be the leader of prominent street gang the Killer Beez.
After the shooting, a woman appeared at the police cordon and asked a reporter "is my brother still there?"
She then spoke to a police officer, before driving away at high speed.
After she had left, another woman arrived at the cordon, identified herself as Masters' sister, and said her brother had been shot, reports Stuff.
Initial enquiries at the scene of the shooting indicated the offender had fled the area.
The gunman remains on the run but police think they know who he is.
