Kerr-Barlow start, Leitch benched
In the backs experienced All Black Tawera Kerr-Barlow will start at scrumhalf this week.
He will get support from Aaron Cruden at flyhalf.
Anton Lienert-Brown moves to inside centre, with the explosive Seta Tamanivalu returning from injury to start at outside centre.
The exciting trio of James Lowe, Sam McNicol and Damian McKenzie complete the backline.
The forwards consist of Kane Hames, Nathan Harris and Atu Moli in the front row.
Dominic Bird and Brodie Retallick continue their dominant locking partnership, with Taleni Seu, Tom Sanders and Sam Cane forming a hard-working loose forward trio.
However, Japan's World Cup captain and Chiefs workhorse Michael Leitch - who has been sidelined with a dislocated thumb since May - returns to provide some impact off the bench.
Players not considered for selection include Nepo Laulala, Mitchell Karpik, Pauliasi Manu, Sam Henwood, Johan Bardoul, Glen Fisiiahi, Maama Vaipulu, Michael Allardice, James Tucker, Charlie Ngatai, Andrew Horrell, Stephen Donald (all injured) and Augustine Pulu (All Black Sevens).
With physical and psychological warfare to ensue, referee Angus Gardner will play a crucial role.
Victory will belong to the side who can maintain composure and thrive on the pressure of play-off rugby.
