Wairoa residents are set to march against gang violence as police hunt a Mongrel Mob member who fired a shotgun into a crowd after a rugby match in the town on Saturday.
Police are still interviewing dozens of witnesses to the shooting at the match between Raupunga the Wairoa-based team Tapuwai.
The Raupunga team had Black Power connections and the Tapuwai team was aligned with the Mongrel Mob, police said.
Sergeant John McCarthy said a white ute carrying six Mongrel Mob members turned up as people were leaving the ground.
Two of the bigger gang members jumped off and chased a 15-year-old boy.
