At least one student involved in last week's mass brawl at an Auckland KFC has been kicked out of school, while others have been stood down.
Meanwhile, police are still working to identify more than 100 students who were involved in the vicious brawl at KFC Mangere East last week.
Knives, planks of wood and chairs were used as weapons in the fight, that had shop owners barricading themselves indoors.
Police sent 13 units and arrested four people in the 5pm incident that was believed to involve students from at least three schools.
A 17-year-old boy was charged with disorderly behaviour, possession of a knife and possession of an offensive weapon.
