Police are looking to round up 10 alleged offenders by the end of the day over a brawl which left an 18-year-old with a knife protruding from his chest.
The fight between two warning Taumarunui families broke out at a home on Taupo Rd at about 1:30pm on Saturday.
It was sparked by an argument where two men traded insults and threats at a school netball game.
Ruapehu Area Commander Steve Mastrovich said one of the families decided to escalate the confrontation into a fist fight after the game.
They travelled to the home of the other family and began assaulting them with bottles of alcohol and firewood, he said.
