Super League champions Bradford have signed Cook Islands prop forward Adam Watene from Castleford.
Watene, who made 28 appearances in helping the Tigers win promotion from National League One last season, becomes the Bulls' fifth new recruit.
Coach Brian Noble said: "We have been impressed with Adam this season and we feel he'll improve in our environment.
"He is big, strong and athletic with very good feet and he will be a great addition to our squad for next season."
