The All Blacks push the rules of rugby to the limit thanks to the indulgence of the referees, France assistant coach Jacques Brunel said on Wednesday.

"The All Blacks try to outsmart the rules and the referees on set pieces and rucks and they benefit from a lot of indulgence," he told journalists at the team's training camp in Marcoussis, south of Paris.

Brunel said head coach Bernard Laporte and manager Jo Maso would raise the point when they meet the referees before the two tests against New Zealand, on Saturday, in Lyon, and a week later at the Stade de France.

"We have the feeling that it's not the referee who is giving the calls Crouch, Stop, Engage at the scrums. The All Blacks impose their own rhythm. They don't bend properly and then go straight from Stop to Engage," he added.

"Their opponents are kept waiting and when you are waiting before entering a scrum you lose all momentum."

Brunel also argued that the All Blacks were illegally disturbing their opponents at the five-metre line-outs.

"They catch the legs of the jumper so it's impossible to develop a rolling maul. They did it several times at Twickenham on Sunday," he said.

New Zealand's 41-20 win over England also confirmed that New Zealand's loose forwards were infringing the rules in the rucks, coming in from the side and preventing their opponents from releasing the ball quickly, he added.

"Richie McCaw is a wonderful player but to be the great scavenger he is, like Serge Betsen he has to be always on the verge of foul play. He gets three or four penalties per game but should get double," Brunel said.

Laporte's assistant said the French were not approaching Saturday's test looking to gain revenge on the All Blacks for the crushing 45-6 defeat they suffered the last time they played New Zealand in France, in November 2004.

"Revenge is not the problem. The players know they are going to face the best team in the world and they are looking forward to the two tests," he said.

"There is a lot of excitement in our camp but it's a constructive excitement because we know we are going to size ourselves up against the best in the world and then we'll have a year to get ready for the World Cup."
