Tana Umaga's assistants Paul Feeney and Glenn Moore are leaving the Blues.
Feeney, a backs coach, and Moore, in charge of the forwards, have decided not to seek re-appointment next season, according to a statement from the franchise.
Moore joined the Blues when former head coach Sir John Kirwan was at the helm, while Feeney joined for this season, Umaga's first at the franchise.
"I intend to seek a more hands-on coaching position," Feeney said. "And believe I now have the skills and ability to succeed in that sort of role."
He said he was looking at several coaching options.
