Blues coach Sir John Kirwan has made a number of changes to his side, some through injury, for Friday night's Super Rugby game against the Rebels in Melbourne.
Captain Jerome Kaino and fullback Charles Piutau were both ruled out for the rest of the season after suffering injuries in last weekend's win over the Western Force.
Steven Luatua takes over the captaincy and the number eight position while Lolagi Visinia moves from wing to fullback.
Ihaia West gets a start at first-five with Dan Bowden not considered because of injury.
Prop Charlie Faumuina and hooker James Parsons are rested with Kirwan naming Tony Woodcock, Keven Mealamu and Angus Ta'avao in the front row.
There are potential debuts off the bench for Greg Pleasants-Tate and Joe Edwards with Simon Hickey looking for his first game of the season.
