All Blacks coach Ian Foster said the Argentinians demonstrated changes in their first two games of the Championship in their attack and defence. He put that down to the work of former international Felipe Contepomi's involvement on attack and defence coach former Kiwis world championship winner David Kidwell.
Foster said: "Clearly, for those who watched their last two games, they're playing a fast, expansive game, and with that typical Argentinian combativeness at the breakdown.
"Those things I don't think will change. But, I think they're playing with a bit more ambition. I'm pretty impressed with what they delivered in their last Test, and I'm sure they're going to be coming here having a no-fear approach for this game, and to give it everything they've got."
Foster said it had been great having former Ireland coach Joe Schmidt involved in the coaching.
He was taking a start slow and build approach since joining the group. But Foster said he had been in discussion with him for a couple of years, and more so in the last couple of months as he moved into his selection role with the team.
The coaching relationship was one where all the coaches were encouraged to challenge Foster on points of concern. That was always the case in the All Blacks' management structure.
"One of the keys for us is to make sure that every Test there has to be an edge, and we've got to be at our best. The key thing after a strong performance is to make sure we really focus on backing that up, and growing from that. That's been our No1 goal this week."
The group from the second Test in South Africa had done a great job in securing a win, and their retention was an opportunity for them to go out and do it again. But he was pleased with how the whole squad was performing.
Georgian referee Nika Amashukeli was not unknown to the All Blacks' management. Foster said he was an up-and-coming referee well regarded by World Rugby.
"He's come through a different system, the Georgian channel, but he is quite a strong ref. Whenever he blows a whistle, he really believes in it. I think we saw that in the Wales-Springbok game that he reffed.
"I'm sure it's a big step for him to come and ref over here but it's part of World Rugby's goal to grow some young refs."
Foster said Beauden Barrett's neck injury that kept him from consideration for the Test was a day-by-day concern, and he had heard nothing to say he would be unavailable next week.
Barrett's replacement on the bench, Stephen Perofeta, has the chance to make his debut.
"He's been preparing well and has been quite impressive behind the scenes," Foster said.
"He's confident, he's happy to talk in front of the group but the main thing is he is leading by learning on the park. He's got a double role to learn [at first five-eighths and fullback] but he's done that particularly well."
