The Warriors will control three teams in 2014 after reaching agreement with the Auckland Rugby League for the NRL club to take over operation of the Vulcans in the New South Wales Cup.
Originally set up by the Mount Albert club as the Auckland Lions in 2007, the Vulcans have until now been run on a joint venture basis between the ARL and the Warriors.
ARL chairman Cameron McGregor said the timing was right for the Warriors to take control. It means the ARL's financial contribution would end and the name will also change.
"Our original aim was to develop an outlet for local amateur players to play at the best level possible but stay in Auckland,'' McGregor said. "A lot of our club players have benefited from the exposure with the Vulcans and have brought that valuable experience back into our Fox Memorial competition.
"Apart from players, the Vulcans have also provided a pathway for our local coaches, football staff, managers and match officials and we look forward to this continuing in the future.
