Liam Messam will cover McCaw's openside position if the skipper is injured.
Hansen said he was expecting a brutal opening to the test.
"The first half hour to 50 minutes is going to be torrid,'' Hansen said. "It could be that it goes right down to the wire. They've got a self belief because of last year and we've got a desire that's pretty high because of last year and both those indicators will tell you that your preparation will be good, it will be genuine and it will be bone deep. And then it comes down to delivering on the day and how you can cope with it.''
Dan Carter will celebrate his 100th test with a start at first-five. Hooker Keven Mealamu retains his place in the No2 jersey, with Dane Coles his back-up.
