The inclusion of the 33-year-old by Hansen is no surprise - the head coach was always going to name his strongest line-up for this match, one of the most popular pool games in the tournament in terms of crowd interest. There will be tweaking for the next match against Namibia at Olympic Stadium four days after the Pumas game, but it is important for the All Blacks and Hansen to make a statement here as defending champions.
Carter will take his place in a team including veterans Keven Mealamu, Tony Woodcock, skipper Richie McCaw, Ma'a Nonu and Conrad Smith. There is youth, too, in the form of right wing Nehe Milner-Skudder, playing in his third test, and he is one of 11 if the match-day squad of 23 about to play their first World Cup game.
The team has an average age of 28 and features 1013 test caps in the starting XV and 316 caps on the bench. About the only minor surprise is that Hansen has gone with no lock cover on the bench against what will be a physical and tough Argentine pack. Luke Romano has missed out to loose forward Victor Vito there.
"We're all itching to get started and with 11 of the 23 players about to take part in their first Rugby World Cup match, there's real excitement, enthusiasm and hunger in the group. We all can't wait for our tournament to start," Hansen said.
"We've had a wonderful reception here in London. The boys have really enjoyed connecting with our fans and this wonderful city. But the business is about to start and we're all looking forward to that because, after all, that's why we're here.
"We've selected what we believe is a very strong team. We have the utmost respect for Argentina who we know a lot more about now because of their involvement in the Rugby Championship. But it also means they know a lot more about us."
Hansen added: "We will need to be at our very best to get our tournament away to a good start. We've had a great preparation and there will be no excuses for not performing on Sunday."
After a long build-up, the phoney war is over. Let the battle commence.
