Logan Swann and Wairangi Koopu will join veteran Ruben Wiki in leaving the Warriors at the end of this National Rugby League season, while utility Aidan Kirk has signed again for the club.
Wiki, who has had 16 years in the NRL, signalled early this year this season would be his last.
Warriors chief executive Wayne Scurrah said tonight Swann, 33, and Koopu, 28, were also going.
"We were delighted when Logan was able to come back to the club from England in 2007 and then have a second year this season," said Scurrah.
"He has indicated he wants to play on in the English Super League and Wairangi told us some time ago that he also wanted to be able to pursue the chance of playing in England."
Swann has so far played 181 times in two stints with the club and sits only behind Stacey Jones (238) for Warriors' appearances. Koopu, in his 10th season as an NRL player, ranks fourth with 158 games.
Kirk, 22, has impressed in recent Warriors' matches and has been signed up for next year with an option for 2010.
Last month captain Steve Price and fullback Wade McKinnon agreed to new deals. Price has signed up for next season, while McKinnon's contract goes through to 2011.
The Warriors have also secured in-form Brisbane winger Denan Kemp on a two-year contract at the end of this season.
