A review of security arrangements at Auckland sports ground Eden Park is likely to see a tightening of the rules ahead of the 2011 Rugby World Cup, Prime Minister John Key says.

Police arrested six people from the crowd of 44,500 after alcohol fuelled fighting at the Four Nations rugby league Test between New Zealand and Australia at Eden Park on Saturday night.

Hundreds of plastic bottles were thrown on the pitch as fighting began inside the stadium, and continued outside after the game. Residents flooded police with calls about unruly and drunken fans.

Police and officials have promised such ugly scenes will not be tolerated when the Rugby World Cup tournament kicks off next year.

Key described the behaviour as a disaster and said there would be a review of the security arrangements and policies ahead of the World Cup.

There would be some toughening up of those arrangements but people were also expected to act like grown ups, he told TVNZ's Breakfast program.

"Even if you say there's no booze that will be sold at Eden Park you can't stop people pre-loading and having far too much alcohol before they get there, you can't stop them buying a pottle of chips and they can go and throw that onto the field if they want."

Some of those at the game on Saturday also booed during the Australian national anthem.

Key said that was outrageous behaviour.

Eden Park Neighbours Association president Mark Donnelly said the stadium management was incompetent and the liquor ban was a mockery.

He said some fans were "tanked up" before they went in and the event was a shambles.

Some fans said they were disgusted and would never go back, the New Zealand Herald reported.

Rugby World Cup organisers said there would be more security and police at Eden Park next year.
