THOMAS MANCH/STUFF Armed police search vehicles after a gang brawl in the Hutt Valley suburb of Stokes Valley, north of Wellington.

"I heard it all going on and have spoken to a couple of people that saw it."

He said gang violence has been a big issue in the area in recent months and residents have had enough.

"Apparently, there were kids around when it was happening. My main concern is that an innocent bystander is going to get hurt."

He said something needs to be done.

"This is like the third time there has been either guns or a knife fight in the last six months in Stokes Valley, and it's because Black Power and Mongrel Mob live on the same street.

THOMAS MANCH/STUFF Twenty-two Mongrel Mob members and 30 Black Power members were involved in the brawl, a resident said.

"It's a pretty easy fix. If you get one of them out of there, then it won't happen."

It has got to the point where he and his partner avoid shopping in the area because of the risk of gang violence.

"I won't go to the local supermarket. I'll drive to Silverstream because I've been down there before and there have been gang fights, and there's been blood and broken bottles on the pavement."

​Stuff had also received reports that some involved in the clash were armed with machetes, however police were unable to confirm these claims.

Armed police were in the George St area, as authorities searched houses in the area to "locate [the] individuals involved".

There have been no reports of injury and Wellington Free Ambulance confirmed that they received no callouts related to the incident on Sunday afternoon.

Police confirmed at least 10 units were at the scene and police staff were posted in the area overnight and they continued their enquiries.

An officer at the scene described it as a "volatile situation".

THOMAS MANCH/STUFF There were no reports of injuries and no arrests in the hours that followed the brawl.

At 5pm, police, including some armed with assault rifles, were seen surrounding a large group of Black Power members who had congregated around a house.

The gang members dissipated as seven police cars left the scene.

By 7pm Sunday no arrests had been made.

Gang members approached by Stuff declined to comment.

One neighbour watching the incident unfold suggested everyone needed to come together and "what do you get when you mix red and blue? Purple. Everyone should wear purple and come together for our whanau".

Police moved onto to Delaney Park on George St, the apparent location of the skirmish, and appeared to conduct another search.
