Aside from the potential switch on the side of the scrum, Hansen saw no reason to alter from the starting XV which made an emphatic statement of intent in the opening test of the season.
"The first two tests I think are about establishing ourselves," he said. "Then, if we have the opportunity and a bit of breathing space, we might make one or two changes. It would be nice to be able to introduce a couple of other young players into test rugby, whether it's off the bench or starting."
One player who is pressing for selection is Blues hooker Keven Mealamu, who has been hampered by a calf injury all season.
"He could probably play this week," Hansen said. "But we'll look to be cautious with him because it's a repeat injury. Give him another week and then we'll be pretty confident that he can come out and play."
The coach, in his first game in charge of the national side, admitted the performance exceeded even his own expectations, as a hat-trick for debutant Julian Savea and tries to Thomson and Conrad Smith proved more than enough to maintain the All Blacks' unbeaten record against Ireland.
"What we were looking for was a really good attitude and to try and establish some forms of patterns that we've been working on. But you also expect your team to take a while to jell when they're coming from five different teams - and they jelled pretty quickly, to be fair, so I'm very happy."
Hansen said he has watched the game twice - "once last night when I was probably a little fogged with a couple of red wines" - and he was impressed with the work of the three debutantes, particularly Chiefs lock Brodie Retallick.
"I felt he played really well. He did a lot of unrewarded work that you don't really get lots of pats on the back for, but the team needs you to do it. Defensively, he was outstanding.
"He's got to be pretty happy with how he's started."
As do the rest of the team. The team for the second test will be named on Thursday but, after such a comprehensive victory with few signs of rust, expect to see a similar side run out for the first time at the new Christchurch Stadium.
