He is still without some key players who are injured for the showdown in Christchurch, but other changes have come about because of the poor performance against Tasman.
Schuler has given starting roles to some inexperienced members of his squad who have all performed well off the bench in the last two games.
NZ Under-20s hooker Nathan Harris gets his first start, ahead of John Pareanga, and is joined in the front row by new tighthead prop Mike Kainga.
Dan Goodwin moves from lock to blindside flanker, replacing Jesse Acton, with Keepa Mewett moving into the engine room to join the impressive Leon Power.
The Steamers welcome back captain Jamie Nutbrown at halfback, who will start a game with top first-five Chris Noakes for the first time since the opening game against Taranaki back in August.
Noakes' flatmate Phil Burleigh is back after concussion. The Highlanders midfielder was sorely missed against Tasman.
Outstanding finisher Lelia Masaga is injured and will miss the Canterbury game, giving the highly promising Jack Wilson a start on the left wing, with the versatile Lance MacDonald switching across to the right wing.
The match kicks off at 4.35pm.
