All Blacks hotel room bugged in Sydney - NZRU

The New Zealand Rugby Union (NZRU) has confirmed Australian police are investigating after a "listening device" was found in the All Blacks' hotel room in Sydney as the world champions prepare to face the Wallabies.

In a major development ahead of Saturday's Rugby Championship opener at ANZ Stadium, the NZRU claims a device was discovered in the team's meeting room, with reports suggesting it was found concealed in a chair.

In a statement, NZRU chief executive Steve Tew said: "A listening device was found in a meeting room this week during a routine security check.

"The hotel immediately launched an investigation, we have informed the Australian Rugby Union, and jointly we have now decided to hand over the investigation to the Australian police.

"We are taking this issue very seriously, and given it will be a police matter, it would not be prudent to go into further details."

Bragging rights are on the line in Sydney this weekend, with two-time defending world champions New Zealand out to continue their dominance against the Wallabies.

While Australia are the reigning Rugby Championship holders, Michael Cheika's Wallabies have not won the Bledisloe Cup since 2002, winning just three of their last 26 meetings against the All Blacks.
