Five Head Hunters gang members have been arrested following a shooting in New Lynn in which one person was critically injured.
A man remains in a serious condition as result of the shooting, said Waitematā CIB Detective Senior Sergeant Megan Goldie.
Each of the men have been charged with unlawful possession of a firearm. But police say the investigation is ongoing and more charges may follow.
Armed police surrounded the Head Hunters' gang headquarters in Henderson on Sunday after police were notified around 3.20pm of reports of a physical altercation between a group of people at an Astley Ave residential address in New Lynn.
"They've surrounded the Head Hunters base and they're demanding they come out one by one at gunpoint," a witness told the Herald.
"They're coming out with their arms up."
All five men appeared at the Waitākere District Court on Monday.
A 25-year-old roofer was charged with being in possession of a .22 rifle in Massey, while the other men - ages 34, 40, 22 and 24 - were all charged with being in possession of a shotgun in New Lynn.
Each of the defendants could face up four years in prison and a $5000 fine if convicted.
Police remained at both locations on Monday.
