The weekend's rugby league match in Auckland offers lessons for the Rugby World Cup, says Prime Minister John Key.
Fans and local residents have complained of a traffic control shambles and embarrassment at drunken behaviour during the match at Eden Park between Australia and New Zealand.
Mr Key says he is disappointed the match was marred by loutish behaviour.
He says the double header, which began with a game between England and Papua New Guinea, had the potential to be a great sporting event.
Mr Key says tougher security measures and rules will be in place to deal with alcohol during the Rugby World Cup.
