Coach Scott Robertson has made five changes to the starting line-up from the side that lost to the Highlanders in Dunedin last Saturday night.
Both Whitelock and Crotty suffered head knocks in the Crusaders loss to the Hurricanes in Wellington two weeks ago and missed the Highlanders match.
Prop Tim Perry returns to start pushing Wyatt Crockett to the bench.
Flanker Billy Harmon will earn his second start replacing All Black Matt Todd, who took a knock to the ribs and will be rested.
Manasa Mataele will start on the right wing in place of All Black Seta Tamanivalu.
