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 forus 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."
Fusitu'a made his debut for the club in 2014 and has developed into one of the game's most prolific wingers. This season he is among the competition leaders in tries scored, and leads the club in linebreaks.
In 75 career matches, the young Marist Saints product has scored 47 tries.
"I'm thankful to the club for having faith in me," Fusitu'a said.
"I grew up always wanting to be a part of the Vodafone Warriors and I'm committed to seeing this club succeed and doing something special here. This is where I want to be."
