The All Blacks like playing under the new laws but have some serious misgivings about the newly introduced line-out change.
Coach Graham Henry said the play was more off-the-cuff under the new experimental law variations (ELVs), although they gave the game less structure and made it harder to coach.
But assistant coach Steve Hansen said the change just introduced in the line-out was only to help the referees, who no longer had to count the numbers of each team.
The new rule meant teams did not have to match up with the same numbers in the line-out.
That rule and one making it legal to collapse mauls have been introduced for the Tri-Nations.
Others, such as free kicks instead of penalties for most infringements, were used during the Super 14.
The new line-out law meant defending teams could put players at the back of the line-out to put pressure on inside backs or crowd the midfield.
Hansen said the change had led to defending teams now having the advantage at line-outs. The All Blacks' line-out had gone awry in the second half of last Saturday's test at Wellington but the new law could be part of the reason, along with the windy conditions.
Assistant coach Wayne Smith said the new laws were not needed by the All Blacks.
They had always played an attacking game, so the ELVs, which were introduced to make a more attractive game, had not made a "hell of a difference".
Henry said the first half of the Super 14 had been a shambles as players tried to work out how to play under the new laws.
But there had been much good rugby played as they adjusted.
