Tonga scored three tries in the final quarter as they came from behind to beat Georgia 23-9 in Tbilisi on Saturday.
Trailing 9-6 on the hour mark, the Islanders turned on the gas, scoring three unanswered tries in 12 minutes to kick off their European tour with a bang.
Replacement scrum-half Taniela Moa came off the bench to score two tries while full-back Vungakoto Lilo added the final nail in the coffin.
Georgia led 6-3 at the interval thanks to two penalties from full-back Kvirikashvili.
Tonga pivot Kurt Morath leveled the scores from the kicking tee soon after the break before Kvirikashvili nudged his side ahead again with half an hour to play.
It was all Tonga in the closing stages though.
