McCaw, who famously played through the latter stages of the Rugby World Cup with what was effectively a broken foot, will again put aside a injury.
However there were concerns that he would not be passed fit, after All Blacks coach Steve Hansen admitted that Sam Cane's inclusion on the bench was directly due to McCaw's leg injury and the potential need to spell the 110-test flanker.
Yet McCaw, while admitting it was sore earlier in the week, shrugged off concerns that he wasn't fit to play.
"I'm fine," the most capped All Black in history said.
"I was a bit ginger last week and I took a while to get going but it's been feeling pretty good for the last couple of days. There was never any doubt really. It's just one of those things that take a while.'
While McCaw has been sighted with padding at training, he was ready again to lead his All Blacks into the coalface.
He said the test against the Springboks in Dunedin was a thorough examination, and would hold the World Champions in good stead coming into their toughest matches of The Investec Rugby Championship.
"Certainly in Dunedin the physicality and intensity of that game was as high as it has been for a long time," he said.
"I think it was a reminder for some and the others who hadn't experienced that before that that's exactly what's going to happen. It will be that sort of intensity and having been through that experience I'm sure we'll all be better for it.
McCaw will look to continue the All Blacks remarkable road record, saying that the best sides were revealed when playing away from home comforts.
"It's different when you get on the road," McCaw said.
"It's a true test of where you're at mentally in your preparation to go and put a performance out there in a different setting.
"That's the sign of good teams. It's all very well to do it home but to get on the road and deal with all the other things you have to deal with and perform, that's the true test. These two weeks are hugely important but we haven't looked too far ahead of tomorrow really."
