Ngatai ruled out with concussion

Supporters can expect an impassioned, physical display as these trans-Tasman rivals go head-to-head in the Chiefs' final round robin home game on New Zealand soil.

Chiefs coach Dave Rennie made two changes to the starting fifteen - which suffered a frustrating loss against the Highlanders in Round 11.

Hooker Nathan Harris earns his first start of the 2016 Super Rugby season, with  moving to the replacement bench.

Anton Lienert-Brown gets a chance to impress at inside centre after Charlie Ngatai was ruled out with concussion.

There are three changes to the replacements.

Siegfried Fisi'ihoi comes onto the bench in jersey No.18, along with Tom Sanders - who returns from injury - to provide loose forward cover.

Experienced campaigner Andrew Horrell bolsters the backline stocks wearing jersey No.22.

Players not considered for selection because of injury include Nepo Laulala, Mitchell Karpik, Augustine Pulu, Johan Bardoul, Pauliasi Manu, Sam Henwood, Tevita Koloamatangi, Tawera Kerr-Barlow, Atu Moli, Glen Fisiiahi, Charlie Ngatai, Sam McNicol and Latu Vaeno.
