Lock Tyler Ardron maintains his spot starting in the second row alongside Brodie Retallick after a massive performance against the Sunwolves, while Taranaki loose forward Pita-Gus Sowakula has been named in the reserves and is in line to make his Super Rugby debut.
Having played in the backline before coming to New Zealand from Fiji, Sowakula was young to the sport but was beginning to find his position in the loose forwards and has a huge amount of potential.
Barnes said his skillset for for a loose forward covering lock set him aside from a number of other players.
"He's certainly an explosive player so we're about to find out what he can give," Barnes said. "He's earned his stripes. He played bloody well in the Mitre 10 Cup and, with people watching that, there was a lot of people looking for him."
Lachlan Boshier, Marty McKenzie and Te Toiroa Tahuriorangi move back to the bench.
The match is the Chiefs' first home clash against a fellow New Zealand team and will see co-captain Sam Cane bring up his 100th for the club.
