Rookie Kiwi international Maumalo is back from a knee complaint after missing last Sunday's 26-6 win over Brisbane, while Gavet reaches his milestone almost six years since making his first-grade debut late in the 2012 season.
Maumalo's reappearance on the left wing is the only change to the starting line-up used in the victory over the Broncos.
Peta Hiku, switched to the left flank after originally being listed at right centre at Suncorp Stadium, has been moved to the interchange to make way for Maumalo.
