Junior Warriors coach John Ackland has advised the club he will not be seeking an extension of his contract for the 2014 season and beyond.
Ackland has been in the role since 2010 after a term as NRL assistant coach from 2006-2009.
He coached the Vodafone Junior Warriors to reach the NYC finals in 2010, 2011 and 2012, including winning the Toyota Cup premiership in both 2010 and 2011.
Ackland, who was part of the club's foundation coaching staff in 1995, returned to the Vodafone Warriors in 2004.
"John has confirmed his intention to move on at the end of the 2013 season," said Warriors chief executive Wayne Scurrah.
