Sam Cane able to sign off on All Blacks century; Joe Schmidt rotates Wallabies side

All Blacks coach Scott Robertson has dropped fly-half Damian McKenzie from his starting side and replaced him with Beauden Barrett for New Zealand's last Test of the Rugby Championship against Australia in Wellington on Saturday.

Sam Cane was named at openside flanker for his 100th test and he will become the 13th All Black to pass the milestone in his final international on New Zealand soil, ahead of the November Internationals in Europe, including a Friday night engagement at Aviva Stadium.

Barrett, who has won 130 caps, will line up with scrum-half TJ Perenara in an experienced half-back partnership at a ground where they played together in Super Rugby for several seasons.

McKenzie and Cortez Ratima drop to the bench.

"We were always planning to give Beauden a go," Robertson told reporters in the New Zealand capital on Thursday.

"We've got to give guys opportunities and build depth in our team and it's a nice chance for Beauden to play outside TJ, they've got a combination, they've played a lot of games together so it lines up nicely.

"(Beauden)'s a great conductor. He'll get you around the field. Obviously, the boot's been impeccable over his career, and he needs to own this opportunity and put a bit of heat on us to make sure that we've got two world class 10s."

The switch of fly-halves means Will Jordan will again start at full-back, as he did last week after twice World Player of the Year Barrett was sidelined by a stomach bug on the morning of the match.

Barrett's brother Jordie, who was ruled out of Saturday's match by a knee injury, is replaced at inside centre by Anton Lienert-Brown.

Perenara, like Cane, is leaving for Japanese club rugby at the end of the season and gets his chance to play his last test in New Zealand
