NZ's Graham Henry believes urgent attention to the laws of the game is required in order to discourage the constant kicking.

Henry believes it has led to a "disappointing" Tri Nations series.

Speaking on the eve of his side's crucial must-win Bledisloe Cup/Tri Nations clash against Australia in Sydney, a frustrated Henry conceded the first four matches of the tournament had not been pretty to watch.

The International Rugby Board's decision not to adopt crucial Experimental Law Variations - which saw free-kicks awarded for most infringements - has seen a return to the dark old days where teams are more likely to kick for field position than they are to run the ball.

"The product that you're looking at I think needs some attention quite frankly," Henry said.

"We like to play - and I'm sure the Australians do too - a pretty ball-in-hand type of rugby and enjoy playing the game, and that's part of the product and we think that's important.

"So I guess the product's not too great and that's disappointing so, I think we need to have some attention on that and I think the people who make the laws and so on try and improve the product."

While the undefeated Springboks have been the main offenders having barely used their backline in three matches, the All Blacks were also guilty of constant kicking in their 22-16 victory over the Wallabies at Eden Park last month.

But Henry, who called for the game's administrators to think outside the box, promised a more expansive approach at ANZ Stadium.

"Usually the Australia-All Black fixtures are pretty entertaining and I think that can be said over a long period of time," he said.

"I had a bit of a talk to (referee) Jonathan Kaplan during the week and I know (Wallabies coach) Robbie (Deans) did too, and he's (Kaplan) keen to make sure it's a game where there's plenty of quick ball and there's no excuses for not having an entertaining spectacle.

"So hopefully that happens."

But skipper Richie McCaw made it abundantly clear winning is his only concern, as the All Blacks look to avoid a third consecutive defeat and keep their slim Tri Nations hopes alive.

"I understand what Graham's saying but I guess when you're out on the field you're just looking for any way possible to win the game," he said.

"And at the moment you get rewarded for putting the ball in the air and playing at the right end of the field and forcing teams into mistakes.

"Maybe that is something that needs to be looked at but I guess just from our point of view looking at the weekend we'll use as much as we can the advantages you get to win the game and that's where I'm coming from at the moment.

"I think you've got to be rewarded for having the skill to use the ball-in-hand - that's what rugby's always been about - but you don't want to do that at the expense of losing the game."

While McCaw understands the magnitude of the challenge that awaits them, he is confident his side can erase the pain of consecutive losses in South Africa with a season-saving performance tomorrow night.

"It's another Test against the Wallabies and they don't come much tougher than that," McCaw said.

"This period of rugby each year is the toughest you'll play and I guess from the team's point of view we're pretty keen to get back on track.

"Obviously we weren't happy with what we've done in the previous two outings and I know the guys are pretty excited about getting that sorted."
