A gang shootout was so chaotic, with yelling and screaming, a witness thought she was at a rugby match.

The woman, who can only be referred to as Witness B, was giving evidence in a trial stemming from an armed gang confrontation in Rotorua on December 11, 2015.

George Robert Jolley, Cramer Tana McMeeking, Chadwick Tamahou Matapuku, Daniel Tere McMeeking, Waimarama Horomai Te Kani, Robert Julian Dashwood, Christopher John Jolley and Major Wetini (also known as Ransfield) are facing a number of charges relating to the confrontation.

Jolley is charged with attempted murder.

Witness B said she'd been helping a friend pack up a Turner Drive house when at least 30 Mangu Kaha members descended on the property.

She told prosecutor Chris Macklin she could pin them to the gang because of the blue, white and black colours worn and the slogans being chanted were that gang's and Black Power.

Members of the group of four or five she was with were yelling back. Frightened, she unsuccessfully attempted to climb a fence to get away.

"Someone was hitting out one of our car's windows with a baseball bat, they were hyped, angry, one of them had a gun, stuck it in his shoulder, it went boom."

The witness recounted how the gun had been re-cocked but didn't fire until it was grabbed by someone else.

That shot had just missed her but hit Wade Pereria in the face and Ben Pereria in the shoulder.

"There was blood dripping down Wade's chest, I hoisted him over the fence."

She said her heart was racing and she was scared.

She told Mr Macklin her feelings were hurt that she'd been shot at because she considered herself part of Mangu Kaha.

She identified Jolley as the first gunman and someone with a tattoo across his face as the second. She claimed other defendants had also been involved but was unable to name them all.
