The Hurricanes have changed both their props for their meeting with the Chiefs in Hamilton on Friday.
Toby Smith and Ben May have come into the starting side in place of Chris Eves and Jeff Toomaga-Allen, who have both dropped out of the matchday 23.
The Wellington side, who haven't won away to the Chiefs for 12 years, have won three of their four games so far this season.
Their only defeat has come against defending champions the Crusaders, but Plumtree admits he wasn't too impressed with his team's display in last weekend's 25-22 win over the Highlanders.
The forwards were below their best, particularly in the scrums, and the coach has opted to shake things up.
Vaea Fifita moves from blindside flanker to lock, with Reed Prinsep starting in the No 6 jersey and lock Liam Mitchell dropping to the bench.
"We're just looking for solutions - it obviously wasn't a good performance from us up front against the Highlanders," said Plumtree. "It's [about] working hard really; I know they've all been doing that."
Wes Goosen will come in on the wing as Ben Lam, whose late try brought the Hurricanes level before Beauden Barrett kicked the winning penalty against the Highlanders, is being rested for the Waikato Stadium clash.
Former Crusaders loose forward Heiden Bedwell-Curtis could get his Hurricanes debut off the bench, while outside back Salesi Rayasi is in line for a Super Rugby debut if he comes on.
Vince Aso has a shoulder injury which could see him out for multiple weeks.
The Hurricanes are 9/25 to win their next game against the Chiefs, who are 11/5.
The Hurricanes are 20/21 conceding a 7.5-points start.
