Sia Soliola turned down interest from Super League to sign a new two-year deal with Canberra.
The 31-year-old has played 73 games for the Raiders since joining from St Helens in 2015.
Several Super League clubs were interested in signing the former New Zealand and Samoa international for 2019, but he has decided to stay at Canberra.
On his decision, he said: “I’m really excited and happy to be remaining in Canberra.
“I broke the news to my son Israel and he’s really excited too. Canberra has become a home for our family and we are looking forward to staying here.
“Although our results on the field haven’t been where we wanted to be this year I know we’ve got a very talented group of players here for the next couple of seasons and I’m very humbled to be a part of that.
“I’m really settled in Canberra and I like to think I’ve still got my best years of footy ahead.”
Soliola enjoyed a five-season with Saints in Super League between 2010 and 2014, scoring 31 tries in 117 appearances.
The back-rower is likely to finish his career in the NRL now.
