New Zealand are the current Bledisloe Cup holders

The game, on 1 November, will be their fourth encounter in 2008 with the other three taking place in the Tri-Nations.

Australian Rugby Union chief John O'Neill said: "It is in our interests to grow the game in Asia - the rewards are extremely significant.

"There's no reason why an event like this could not be held in other places within Asia - Tokyo is a possibility."

November's clash - which will kick off at 1630 local time (0830 GMT) - will be the first time the two great rivals have met in a Test outside New Zealand or Australia, except in a Rugby World Cup.

The All Blacks will head to Britain after the game for Tests with Scotland (8 November), Ireland (15 November) and Wales (22 November), while the Wallabies play England at Twickenham on 15 November.

If the 2008 Bledisloe Cup series is level after the Hong Kong match, New Zealand - as the current holders - will retain the trophy.

It was first awarded to the winning team in matches between the two antipodean rivals in 1932. The All Blacks have held it since 2003.
