Christchurch police say spectators at a college rugby match in Christchurch were well-behaved.
The annual game between Christ's College and Christchurch Boys High School - held for more than century - has been marred in recent years by poor spectator behaviour.
Last year police had to break up a drunken brawl among spectators, prompting breath testing this year.
Christchurch Boys' headmaster Trevor McIntyre says former students of both schools have unwisely decided it's okay to become intoxicated, then cause problems at the game.
People were breath tested before being allowed in on Tuesday, and 30 police patrolled Christ's College grounds.
Senior Sergeant Murray Hurst says only a handful of people were turned away at the gates.
Boys' High won the match 25-12.
