All six of Rocco Berry's appearances in 2026 came for the New South Wales Cup side, after injury sidelined the 25-year-old centre for much of the season.
The Warriors have nevertheless extended the 50-cap player through the 2027 NRL season.
The club had previously extended Berry through 2026 after his impressive 2023 season.
Head coach Andrew Webster, whose contract runs through 2032, backed the club's decision.
"We have so much belief in him," Webster said.
"We know the player Rocco can be, and we're committed to giving him every opportunity to return to his best," Andrew McFadden said.
McFadden said Berry had faced challenges, especially in 2026, while working to return to the NRL.
George told Sport Nation on Tuesday: "He is a positive influence around the club."
