He has named four new boys in his side and said they were excited to be playing.
"You have got some people getting their first game. It is always interesting when they come on the scene," Hansen said.
He said getting new guys in the team was getting them comfortable enough in the team that they were willing to express themselves when playing.
"You have to make sure mentally they are ready.
"No doubt, from an athletic and talent-wise point of view, they are ready. But have they got the mental fortitude going into that arena for the first time.
"So when you have four of them ... you don't want to put them all on the park in the same time, but at some point you will see them all on there."
Hansen said playing well on the Saturday came back to the preparation from the Sunday to the Friday.
New players did not want to get overloaded with information.
The new players - flanker Shannon Frizell, midfield back Jack Goodhue, lock-flanker Jackson Hemopo and first five-eighth Richie Mo'unga - bring the total of All Blacks near to 60 in the past two years.
When asked what was causing the high injury toll that was forcing him to use more players, Hansen said it was partly because of the way the Super Rugby competition was set up.
"We play each other twice ... it is what it is. You can't change that. Everyone knows the Super competition is going to have some changes. But on top of that you've got all the travel. So you have some weary athletes and that always creates the risk of injury."
Hansen said Goodhue was a mature young man and had some real qualities about his play.
Jackson Hemopo was showing good enthusiasm.
"It is a real good opportunity for him. He has benefited from someone else's bad luck in Liam Squire ... we are excited by what we have seen. He is a real learner and a physical player and we look forward to seeing him on the park."
Hemopo did not have the speed of other loose forwards but was very tough. Ideally, his position internationally would be on the blindside.
Training this week had shown plenty of intensity, which was expected.
"We have had a far better week and more genuine preparation week. Last Saturday's game I consider a gift. It was such a learning opportunity. From what I have seen so far, a lot of that learning has been taken up. We will get some further proof on that with the next performance."
