Liam Coltman starts at hooker in place of Ash Dixon who was ruled out due to a back injury. Greg Pleasants-Tate takes the vacant spot on the pine as a result.
Josh Renton also joins the match-day squad, beating out Kayne Hammington for the reserve halfback role.
The Highlanders enter the match against the Stormers fresh off the bye and looking for their second straight win on home soil. While the Stormers come into the match on the back of two losses, Mauger said he was expecting a tough affair.
"The Stormers are a big side so we expect a physical encounter, they are also a dangerous team with ball in hand in open spaces, so we are well aware of those threats and have prepared to meet those challenges," he said.
The match is the third and final of an away trip for the South African side, after visiting the Waratahs in Sydney and the Crusaders in Christchurch over the past fortnight.
Their only win of the season so far came in their opening match against the Jaguares.
