Winger Denny Solomona has signed a new contract with Castleford that keeps him with the club for another three seasons.
The New Zealander scored 18 tries in 15 starts for the Tigers in 2015 after joining from London Broncos.
Previously of Melbourne Storm, the 22-year-old said: "I'm so happy to have extended my deal to stay here at Cas Tigers for the coming three seasons.
"Everyone has made me feel at home here and we have a great team both on and off the pitch. I'm surrounded by players and coaches who are helping me to constantly improve my game, and I know I can continue to grow as a player in this environment."
Coach Daryl Powell welcomed the news and believes Solomona can become the best winger in the country.
"Denny can become the best winger in Super League if he continues the hard work and application he has shown so far this pre-season," he said.
