Castleford have agreed a deal to sign Leeds Rhinos second rower Weller Hauraki on a two-year contract.
The 27-year-old moved to Leeds from Crusaders in 2010 and will join Cas ahead of next season.
Coach Ian Millward said: "His experience and exceptional attacking qualities will provide us with great stability and composure on the field.
"He is a tough competitor and with his boxing background, I expect him to be a leading figure in training too."
The New Zealander is the seventh player to commit to the Tigers, who finished 13th in Super League, for next season.
