In the forwards, the hosts have an experienced front row of Andrew Hore, Tony Woodcock and Owen Franks, while new cap Brodie Retallick will join Sam Whitelock in the second row.
Victor Vito will don the number 6 jersey in the absence of the injured Jerome Kaino, and the back row is completed by captain Richie McCaw and Kieran Read.
In the backs, debutant scrum half Aaron Smith will have Daniel Carter outside him, while Sonny Bill Williams and Conrad Smith link up in the centre.
Zac Guildford and Test newcomer Julian Savea will fill the wing berths, with the 12-times capped Israel Dagg selected at full-back.
This is New Zealand's first Test match since they beat France 8-7 to win the Rugby World Cup on home soil last October.
In all, the Hansen-led management team have made eight changes in personnel to that final-winning fifteen, with the returning Hore and Carter boosting the side's caps tally by a considerable 147.
Commenting on the team selection, Hansen said: "We picked them (the new caps) in the squad because they have all shown that they have special qualities which they now get the opportunity to show on the international stage.
"The build-up so far this week has been good. With such a short preparation time, we have focused on keeping things simple and bringing the team together.
"We have been concentrating on making sure we have clarity early in the week, increasing intensity and accuracy as the week goes on, which should allow us to put in a performance that we can be proud of on Saturday."
