Police crackdown on bars during RWC

Police say three central Auckland bars served alcohol to an underage girl and eight motorists were caught drink-driving around the time the Rugby World Cup quarter-final played on Sunday morning.

As the All Blacks took on France, police visited bars and conducted drink-driving checkpoints across the country.

In Auckland City, road policing manager Inspector Andy King said police tested 522 drivers at four checkpoints - of which 32 failed the initial test.

Of those 32 drivers, eight failed further screening tests and are facing charges for drink-driving.

As well as drink-drivers, officers also visited establishments hosting morning RWC celebrations that served alcohol during games under new legislation.

Youth and communities manager Inspector Mark Benefield said a 15-year-old girl was served alcohol at three central city bars on Sunday morning.

"We visited nine bars and three failed. They sold to a 15-year-old girl and we are very disappointed that they have done so and that they don't have the processes in place to ensure [minors are not served]."

The teen was not asked for identification when ordering drinks, he said.

A bar with "dancing ladies" was also shut down because patrons "were not interested in watching the rugby".

Establishments serving alcohol must be open solely to screen the rugby, according to the legislation.

"Behaviour around the bars has been good at the times the games are on," Mr Benefield said.

"Our biggest concern was that people would continue drinking ... but that hasn't seemed to happen."
