"I knew I was going into the last season of my contract and I was hoping the big boss wanted me to stay. I was glad to get it all sorted quickly and I know my wife and kids feel the same about life here.
"I feel like I've made progress every year I've been with the club, and I'm not about to stop. I want to keep pushing myself, keep challenging myself to the limit and never thinking I'm completely happy with my game. I want to make my family and the Falcons supporters proud, and that's my motivation."
The 26-year-old was one of the Falcons' standout performers last season, scoring six tries in his 13 Aviva Premiership appearances and kicking goals at a rate of 88 per cent, the second-highest in the division based on a minimum of 20 attempts.
He has played 23 tests for his native Tonga and was a member of the Mid Northern rugby side when playing in Northland.
