The All Black coaching team say switching over to rugby's latest global law changes shouldn't be a disruption as they prepare for the 2009 test season.

Both the All Blacks and France will play under the new laws for the first time when they meet at Carisbrook on Saturday night.

The International Rugby Board made the changes last month following a year-long trial of the ELVs, although several of the experimental laws were overlooked by European rugby bosses.

Gone from the laws regularly played by New Zealand's best are the sanction variations, which saw free-kicks replacing penalties for many offences.

Both sides will now have to limits on the number of players they can put in a line-out and the ELV allowing for defending sides to drag down attack rolling mauls is also gone.

Last year the All Black coaching staff admitted they had been out-coached by Wallabies coach Robbie Deans in the early stages of the Tri Nations in terms of the ELVs.

But head coach Graham Henry said the coaching staff didn't have similar concerns ahead of the Iveco Series, with the rules new to both teams and coaching set-ups.

Instead, he said his biggest concern was ensuring the rules were properly enforced.

"Well we are all in the same boat, we are all starting on the same start line," Henry said.

"It will be interesting to see how we do adapt; it is going to be a big game at the breakdown.

"It will be a good game for the viewers to watch, it will be easier for the referee hopefully and we are going to get a better game of football.

"We may get more scrums. And as long as we get to keep the scrums up, that would be good; shoulders and head above hips and hitting square.

"And we may get a few more penalties. So I think our discipline is going to be important because you don't want to be booted off the park.

"And I think this game can get to that situation if you are not disciplined enough. It is going to be long-arm penalties and not free-kicks."

Meanwhile, backs coach Wayne Smith has questioned why law makers continued to tinker with the game's rule book.

"Whilst they change laws to legislate to try and make the game more attractive, I don't think you need to," he said.

"It is up to coaches and players to decide how you want to play."

Smith said it was understandable that the latest changes, which will be in force at least through to the 2011 Rugby World Cup, would impact on what sort of game-plan teams such as the All Blacks adopted.

But he said he doubted it would relate to major changes.

"You have to fine-tune things," he said.

"But as I have said before, laws always give you the opportunity to have a choice.

"You choose the way you want to play; that could be a 15-man game, a 10-man game. It could be a mauling game, it could be a rucking game.

"You have choices."
