Junior Moors has signed a two-year contract extension keeping him with Castleford at least until the end of the 2019 season.
Moors joined the Tigers ahead of the 2015 season from the Melbourne Storm.
He said: “I’m really happy to have extended my deal with Cas.
“My family and I are really settled here and I love playing with these boys.”
Tigers coach Daryl Powell said: “I’m delighted that Junior has agreed to extend his contract with the club.
“I have no doubt that he will continue to improve and we will see the very best of Junior Moors in the next few years.”
