Parliament's passed legislation relaxing liquor laws for the Rugby World Cup.

MORE: Rugby World Cup alcohol Bill expected to receive support

MPs have passed the legislation, which will allow bars to have extended trading hours during Rugby World Cup games, by 99 votes to 21.

The Green Party, the Maori Party and five Labour MPs opposed the Bill.

Sponsored by Act leader David Seymour, it will allow bars, pubs and licensed clubs to open and televise any of the 2015 Rugby World Cup games.

The licensee can open up an hour before each televised game but must close for the sale of alcohol 30 minutes after the end of each game - unless it is within an hour of the next televised game.

District Licensing Committees can approve licenses for special events but Mr Seymour had heard that some were putting conditions on them, such as required a special speaker or a costumed event, although in some areas special licenses had already been granted.

There will be conditions to bars extending hours to show RWC games: there must be no outdoor speakers; no discarding of empty bottles and no use of outdoor courtyard areas.

Police would have to be given seven days' notice. Premises which have had their licenses varied or suspended in the previous 12 months will not be able to extend their hours to show Rugby World Cup games.

And if the police lodge an application to suspend or cancel a license during the RWC period, the premise concerned will no longer be able to show games during extended periods.

The Rugby World Cup begins in Britain on September 19 and the final is on November 1.
