Warriors owner Eric Watson is taking over the chairmanship of the club.
And in further changes, the club has appointed successful Auckland businesswoman Niki Schuck to its board.
The reshaping of the NRL franchise's board follows Watson's move to acquire sole ownership of the club late last year after a fallout with co-owner Sir Owen Glenn.
It's the first time since Watson acquired the club in late 2000 that he has been a 100 per cent shareholder.
Under the new ownership model he becomes chairman, taking over from Bill Wavish who has been in the role since 2012. Wavish remains on the board as a director.
