Jared Waerea-Hargreaves will stay in the red, white and blue until at least the end of 2020 after signing a new deal.
The 27-year-old Kiwi international has been rewarded for his outstanding form in 2016, adding a further three years to his existing contract.
“Everyone who knows me knows how much the Roosters mean to me,” Waerea-Hargreaves said.
“It’s an honor to wear the Roosters jersey and to represent our area, and I consider myself incredibly fortunate to know that I’ll continue to be part of the team we have here for at least the next four years."
"He's a key leader of our forward pack on the field, and as vice-captain, an integral member of our leadership group off the field, so it’s great to know that Jared will continue to play his role at the Roosters in the coming years," Coach Trent Robinson said.
