Canberra Raiders outside back Sisa Waqa has been granted a release from the NRL club to join French rugby outfit FC Grenoble at the end of June.

Waqa, off contract with Canberra after this year, was linked to a French rugby move midway through last season after his manager sought a release.

The Raiders said Waqa would remain part of the club's NRL squad until his release and would continue to train and play.

Waqa said the decision was a tough one and that he remained committed to the Raiders until his release was finalised.
