A rugby player was taken to hospital with cuts to his leg following a fight, which involved a broken window, after a game in Taupo.
The fight broke out on Saturday afternoon at Owen Delany Park following a club match between Waitomo and Taupo Sports, which Waitomo won 22-13.
The two teams were entering the changing rooms after the game when the fight started, according to the King Country Rugby Union.
Police and the rugby union are both investigating the incident, which involved two players from opposing teams.
Bay of Plenty police communications manager Kim Perks said a window was broken during the incident, which caused the leg injury to one of the players.
