The Kingdom beat the Cook Islands 29-12 in the fifth place playoff at the Oceania Sevens in Suva last weekend to qualify for the Hamilton and Sydney legs of the World Series next year, as well as World Series Qualifier event in Hong Kong.
Tonga last featured on the World Series five years ago when they failed to win a game at the Gold Coast and Wellington events.
The Kingdom did qualify for the Rugby World Cup Sevens in San Francisco earlier this year but were beaten by Kenya in the preliminary round.
