The Wallabies are putting the blinkers on about who will wear the vacant All Blacks No 10 jersey, saying they are only focused on improving their own game.
Injury-hit New Zealand will field their fourth-string five-eighths in Saturday's Wellington test, where they can wrap up the Bledisloe Cup.
Colin Slade or Tom Taylor will fill in following the injury-enforced absence of Dan Carter, Aaron Cruden and Beauden Barrett.
Wallabies inside centre Christian Leali'ifano believed the All Blacks wouldn't have any problems adapting to Slade or Crusaders rookie Tom Taylor.
"Anyone they've produced so far has done a fantastic job so I'm sure the next replacement will be equally as good."
He said his team were more concerned about improving on their 47-29 loss in the opening test in Sydney.
The Wallabies felt confident that after spending only one week working on combinations under new coach Ewen McKenzie that would happen.
"We've got to try not to worry too much about their changes, we've got to look back at our game and try to improve and minimise our mistakes," Leali'ifano said.
Meanwhile, injury-prone Wallabies backrower Hugh McMeniman is out and will undergo a shoulder reconstruction. His Western Force teammate Scott Fardy most likely will start.
