Two streakers bearing the Vodafone logo on their bodies invaded the pitch during the second half of the match in Sydney.

Police Superintendent Commander Allan Wilson said at a news conference on Monday that Vodafone could face significant penalties.

"There are appropriate laws, appropriate penalties as well, in relation to anyone who incites or encourages any criminal offences so that law is in place and we wish to have that as a deterrent in future," he said.

Wilson said the incident was not a good advert for the sport.

"I think it's bad publicity for the game itself and I think that what went on was an unlawful stunt, if that's the reasoning behind it, but that's yet to be determined."

The streakers ran up to and around All Blacks fly-half Andrew Mehrtens as he was preparing for a crucial penalty kick.

After the men were removed by security, Mehrtens missed the kick and the All Blacks went on to lose the match 16-14 against their bitter rivals.

Maher said he had agreed to pay any fines the pranksters incurred for their stunt at the old Olympic Stadium in Sydney, which is sponsored by one of their main rivals.
