Inside centre Latiume Fosita replaces Sione Piukala, who started in the 45-16 defeat against Argentina.
Six Tonga players will make their fourth starts of the tournament: Sione Kalamafoni, Viliami Ma'afu, Sonatane Takulua, Siale Piutau, Telusa Veainu and Vungakoto Lilo.
Tonga must beat defending champions New Zealand and hope Argentina lose to Namibia in their final game if they are to reach the quarter-finals.
