The Raiders can add 'assistant coach' to their lengthy shopping list, with support staffer Matt Parish being granted an immediate release to return to Sydney for personal reasons.

Parish, who followed Ricky Stuart from the Eels to the nation's capital last year as part of his coaching staff, was contracted to the Raiders until the end of 2016, but will instead return to Sydney in a bid to find employment closer to his family next year.

Raiders CEO Don Furner confirmed the club and Parish had reached a mutual agreement to part ways after the former Tigers utility informed management of his intentions to leave upon returning from NSW's successful Origin campaign where he acted as Laurie Daley's assistant.

“Matt sought an early release from the final year of his contract for family reasons and the Raiders were sympathetic to that request," Furner said.

"Both parties agreed it was important for this to happen now to minimise the disruption to the team and maximise the chances of Matt securing his coaching future and the Raiders finding a suitable replacement.

"Matt has been a fantastic asset for us this season and we wish him all the best for his future in the game.”

The news comes amid speculation fellow assistant Brett Kimmorley could also depart the club to take up Wayne Bennett's vacant post at the Knights, while the club still searches for a marquee player signing having missed out on the likes of James Tedesco, Kevin Proctor and Josh Mansour already this year.
