Police have been called in after a referee was punched in the face at the end of a schoolboy rugby match in Auckland.
Auckland Rugby Referees Association chairman Don Crawford said the referee was punched in the face twice, allegedly by a spectator, at the Auckland secondary schools rugby final between Auckland Grammar School and De La Salle College on Saturday.
The game was played at the Tamaki College grounds as part of the championship final for the 2B grade.
Mr Crawford believed the spectator was supporting the De La Salle team, which lost the game.
Police were called to the ground but they were not able to identify the offender.
"We'll be working with the police and the school to identify the person," Mr Crawford said.
There were a lot of witnesses but none had come forward.
"We understand they closed ranks on the person, but we'll certainly be dealing very heavily with the school (De La Salle), with the headmaster and the chairman of the board of trustees."
Mr Crawford said the referee was okay after the attack. "It's just wasn't a very pleasant thing to happen after the game."
There was "zero tolerance" to physical or verbal abuse against referees, he said.
"If there are any incidents we'll take it as far as we can through judicial measures. Whether it be a player or a coach, we'll take it to the police."
An official complaint had been made to police, he said.
The Auckland Secondary Schools Rugby Association and Auckland Rugby will also be involved in investigations into the incident.
De La Salle College principal Myles Hogarty was unable to be contacted today.
In a school newsletter on Friday he said the school had three teams in finals games over the weekend.
"They will play with great heart, passion, skill and sportsmanship while proudly wearing the De La Salle crest on their chests," he said in the newsletter.
Auckland Grammar School principal John Morris said today he couldn't comment until he had spoken with the team's coach, Mark Bella, today..
