New Zealand will not allow thoughts of next year's Rugby World Cup on home soil to distract them during their Grand Slam tour of Britain and Ireland, according to captain Richie McCaw.

The All Blacks underlined their status as the world's number one side with an unbeaten success in the Tri Nations earlier this year, with their impressive multi-phase game proving too much to handle for traditional rivals Australia and South Africa.

Graham Henry's men are currently in Hong Kong preparing to take on the Wallabies on Saturday, from there they will head to Britain and Ireland to face England, Scotland, Ireland and Wales as they seek a third clean sweep of the home nations in the last six seasons.

The men in black have not lost to England since 2003, Wales have to go back 57 years for their last success and Ireland and Scotland have yet to record victories against the Kiwis.

But openside flanker McCaw, the world's leading exponent at the breakdown, is taking nothing for granted and does not believe his side can afford to have an eye on 2011's global showpiece, where they will attempt to shake a 24-year hoodoo of failing to bring home the game's biggest prize.

"You talk about Grand Slams and it's something you want to be a part of. They are tough because you want to be right every week. To go home having beaten all four teams is very satisfying.

"World Cups are important but in the All Blacks it is not acceptable to turn up and not perform.

"Every team can get beaten and if you don't get things dead right you will be. As soon as you start thinking you're better than anyone else just because you've won a few games, that's when you come unstuck."

The All Blacks have proven the most adept at adjusting to the new law interpretations at the breakdown, introduced earlier this year in an effort to afford attacking sides more leeway at ruck time, with their accuracy in attack proving to be breathtaking on occasions.

And McCaw is a fan of the tinkering with the rules, although he admitted he had some reservations initially.

"They are not new laws, it's an interpretation," he said.

"In the Super 14 it was at the other end of the spectrum and it was frustrating but we are now seeing a lot of things that you want to see happening.

"You get rewards for keeping hold of and using the ball, if you defend well you also get the chance to contest the breakdown and it makes it a better game for people to watch and to play."
