Star winger David Fusitu'a will remain with the Warriors until the end of the 2023 NRL season.
The 23-year-old has been in stellar form this season, scoring 15 tries in 18 appearances and the deal will see him become just the ninth 10-season Warrior.
"Retaining David was a priority for us and we're thrilled to see him staying here long-term," Warriors head coach Stephen Kearney said.
"There's no question he has made tremendous progress, especially over the last two seasons. He provides wonderful value for us in all respects.
"He's a player the club has put a lot of work into to develop into a high-quality footballer and he is repaying the faith we have always had in him."
