Loosehead prop Arizona Taumalolo is on the bench, replaced by Toby Smith. Hika Elliot replaces Mahonri Schwalger at hooker and No 8 Kane Thompson comes in for Alex Bradley, who has also been dropped from the squad. Tawera Kerr-Barlow comes in for Brendon Leonard at halfback and Jackson Willison predictably replaces centre Richard Kahui, who dislocated a shoulder against the Reds.
There is no room in the starting line-up for flanker Sam Cane, referred to by Steve Hansen as a potential replacement for Richie McCaw when named in the All Blacks wider training group recently.
