The Warriors have released front-rower Albert Vete, but re-signed NRL assistant coaches Stacey Jones and Tony Iro.
Vete will make a mid-season transfer to continue his career in Australia with reports he is close to joining Melbourne - who recently missed out in their attempt to lure fellow Warriors front-rower Chris Satae away from the Auckland-based club.
The 25-year-old Tongan international has struggled for game time this season - making just two NRL appearances - and departs after making 46 appearances since debuting against Newcastle in round one of the 2015 season.
"We really appreciate the contribution Albie has made to the club both on the field and off it," said Warriors general manager football Brian Smith.
"He was among a group of young players who came through the system in 2015 and finishes just short of the 50-game milestone. We wish Albie and his family all the best for the future."
