All Blacks fly-half Dan Carter will not be rushed back into action by Steve Hansen, who said he will give his 10 more time to recover from a calf strain.
Hansen revealed on Sunday that Carter, the world's leading points-scorer in Tests, is not being considered for the clash with the Boks.
His place will again be taken by Chiefs playmaker Aaron Cruden, who had a shaky game against Argentina in testing conditions in Wellington.
New Zealand beat the Pumas to remain unbeaten after three rounds of the Rugby Championship.
"He's getting older isn't he and the more you play the game the more vulnerable you are to injury and he's got quite a few miles on the clock," Hansen said of Carter in assessing his fitness.
