Vaioleti started to play rugby for Club Levengamalie in 2003.[1] After a club tour to New Zealand, he was persuaded to turn professional and in 2005,[1] was selected to play for Tonga against France. While in France, he was approached to play club rugby in Europe. As a result of this, Vaioleti played one season with Royan in France.[4] From there along with some fellow Tongan players, he moved to England to play for Hertford in 2006.[4] In 2007, Vaioleti joined Jersey[5] where he became captain and led them to two promotions and a game at Twickenham Stadium in London.[4] In 2010, Vaioleti left Jersey to move to Wharfedale after a recommendation from fellow Tongan, Latu Makaafi.[5] After a season, in 2011 he moved to Rotherham Titans where despite making 8 appearances for them in the RFU Championship, due to a lack of starts he moved back to Jersey, who had just been promoted to the RFU Championship, in 2012.[6]
Vaioleti has represented Tonga twice as well as appeared a number of times for Tonga A. In 2010 he received an invitation to represent The Barbarians under England national coach, Brian Ashton against a Forces XV where he scored two tries.[4]
