The other three changes are injury-related, with Ethan de Groot (concussion), Tyrel Lomax (thumb) and Beauden Barrett (shoulder) replaced by Tamaiti Williams, Fletcher Newell and Damian McKenzie, respectively.
On the bench, George Bower, Pasilio Tosi, Rieko Ioane and Ruben Love join the match-day side.
Robertson said the team was looking forward to building on the performance at Eden Park, as the Rugby Championship goes down to the wire.
“We saw how competitive and determined the Wallabies were in Auckland last weekend, staying in the fight right to the end,” Robertson said.
“We expect another tough contest this Saturday. We have picked a 23 to go toe-to-toe with a quality Australian team.
“It’s all up for grabs in what has been the most even Rugby Championship we’ve ever seen, and we’re here to cap off this competition with a performance we can be proud of.”
The All Blacks need to win to have a chance of winning the Rugby Championship for the first time since 2023.
After the test, there will be a brief break before an extended squad is named for the November internationals in the Northern Hemisphere, where the All Blacks will face Ireland, Scotland, England and Wales.
