Tangata has been playing for English semi-professional club Halifax since 2015 season. He played briefly for Widnes Vikings before returning to Halifax. Both clubs play in the Championship, which is a tier below the Super League.
Halifax RLFC in a statement said “Adam has had to deal with more than most and goes with our best wishes, we are proud to have assisted him on his journey. He is very grateful to all the fans, sponsors and players at Halifax for the assistance in making this possible.”
Halifax manager Simon Grix said “I'd like to wish Adam the best of luck with this opportunity. This was his aim since leaving home to join Halifax and we felt we couldn't deny him that.
“He was fielding offers from Super League and this was inevitable, so we have cut a deal that works both ways. We had our eye on Keegan for next season, this way Adam gets his chance and Keegan gets to have a look at us.
“Adam will be missed, and we definitely did not want to see him leave. We wish him all the best for the future.”
Tangata will join fellow Cook Islander Tinirau Arona, who plays for Wakefield Trinity.
Halifax confirmed that Keegan Hirst has agreed to join the team on loan until the end of the current season.
Football manager Ian Croad said: “This is a perfect fit as Keegan is under consideration by Simon Grix for next season. It gives both parties the opportunity to try each other out. Keegan needs no introduction and I’m sure he will be an instant hit with the fans.”
Simon Grix added, “Keegan is an experienced front row who has benefited greatly from his time in the full-time game. He has a good engine and will provide significant size to our forward pack, he'll come straight into contention for the weekend.
