The news will delight Rovers fans who have been thrilled by the former Australia stand-off’s skills since moving from Canberra Raiders during the winter.
Campese, 30, had only signed a 12-month contract with the East Yorkshire club and was, unsurprisingly, courting attention from rivals following his excellent start to life in Super League.
However, he has now penned a two-year extension with Hull KR until the end of 2017 with the new deal also including an option for a third year.
Campese, who hopes to lead them to victory at derby rivals Hull FC tomorrow night, said: “We’re only seven games into the season but I think we’ve shown some good signs that we can do something this year.
“This club is definitely going places and I’m glad to be a part of it.
“I’ve really enjoyed my time here since arriving in the New Year. The coaching staff have been excellent, the boys are a tight-knit group and I couldn’t ask for it to have run any smoother to be honest.
“That made it an easy decision in that I know what I’ve got here at Hull KR, how good the club is and how mad the fans are!”
Campese, a New South Wales State of Origin representative, captained Canberra for three years before leaving the NRL.
Rovers head coach Chris Chester said: “I’ve been hugely impressed with Terry since he arrived at the club and he is a pleasure to work with.
“He’s the leader of the group and a player that the other blokes look up to. He’s been instrumental in creating the culture that we currently have in the squad and he will have a huge role to play for us over the next few years.
“I’m sure having his future sorted will really allow him to focus on his family and his rugby and we’re really excited about extending his stay with us.”
