The obvious candidates to be rested this week are Sam Whitelock, Aaron Smith and Beauden Barrett.
Scott Barrett could start in place of the former, with Whitelock given the week off. While TJ Perenera and Lima Sopoaga could come in for the latter two - who both drop to the bench - and be given the chance to build their combination and also gain invaluable experience in managing the gameplan.
"I wouldn't call whatever we do experimenting," said Hansen. "If you go out there and you have an All Blacks jersey on then you are a good player.
"It is well documented that we have a big season and we are not even halfway through it and we have still got a lot of travelling to do.
"So at some point we are going to have to be smart about who we select."
Some of the desire to change the team will be tempered a little no doubt by the relative lack of game time some regular starters have had.
Dane Coles has missed most of the season due to injury and the desire is presumably to keep him going.
Liam Squire is another who is short of game time having missed eight weeks with a broken thumb. He's still trying to find his feet at this level so potentially he will start again with Vaea Fifita given a place on the bench.
With Owen Franks having been forced out of action ahead of the Dunedin clash, the Nepo Laulala/Ofa Tu'ungafasi combination at tighthead has already taken its first steps.
The back three is definitely going to change in make-up as Ben Smith has begun his sabbatical. Israel Dagg is going to come back into the side, the question now is whether it's at fullback or wing.
The preference is to use him on the wing and that will give the selectors the choice of handing a test début to David Havili or persevering with Damian McKenzie who for all his obvious talents and excitement, was loose in periods in both tests against the Wallabies.
"It's a fine line," said Hansen on trying to balance the need to win, keep players fresh and have in mind the dangers the Springboks pose next week and therefore the need for continuity of performance.
"On one hand you're looking to grow your squad. On the other hand you're trying to grow combinations. If you chuck in all the travelling as well - there's a lot of juggling. Whatever we do it will cause some conversations so that will be good for the game. The expectation will be that we will field a very good side and we'll go from there. It doesn't matter who plays, the expectation is we play well and that won't change."
