All Blacks coach Steve Hansen wants the third and final Bledisloe Cup Test to be played according to the experimental law variations.

The new rule changes have come into effect in New Zealand's national provincial championship and also in the new Northern Hemisphere season.

The two main changes are the limit of five seconds for the ball to be cleared from the back of a ruck and a shortened scrum engagement.

The year's last Bledisloe Test, a dead rubber given the All Blacks' 2-0 lead in the series, will be in Brisbane on October 20 after the completion of the four-nation Rugby Championship.

Both the All Blacks and Wallabies then head to Europe in November for their respective end-of-season tours.

Hansen said the schedule made it logical to adopt the experimental rules when the trans-Tasman rivals clash at Suncorp Stadium.

"We've asked for that," he said on Saturday before the All Blacks headed to Argentina for the next round of the Rugby Championship.

"It makes sense. Both teams are going to the Northern Hemisphere, where they are already playing those rules, so commonsense would suggest that we should play under them."

Hansen said it was a case of wait and see as to what the authorities decided, but believed the Wallabies would be in favour.

"I'm pretty sure Australia will be keen as we are."
