Ackland sought a contract extension in February but was told by chief executive Wayne Scurrah to wait so Elliott could get to know him better, but Ackland and the new coach haven't always seen eye-to-eye. Elliott has made significant changes since his arrival and is clear on where he wants to take the club.
"When Matt Elliott was appointed last October, he had some definite ideas on how we could further improve our overall recruitment and development structure," Scurrah said. "Matt and [general manager football] Dean Bell are reviewing the current structure and future plans. As well as announcing the new NYC coach, we will also be in a position to reveal details of this in the near future."
The timing of the announcement is interesting. It's understood Ackland informed the club a few weeks ago he would be leaving but it wasn't confirmed until yesterday, a couple of days after the Warriors won their third straight game.
They also announced the re-signing of five players - props Sione Lousi, Suaia Matagi and Charlie Gubb plus utility Pita Godinet until the end of 2014 and forward Sam Lousi until the end of 2015.
It's not clear what Ackland will do next but it's possible he will return to his former job as a New Zealand-based scout for Australian clubs.
He is a popular figure in New Zealand league circles and was seen as a link to the local game. He has long promoted local talent and is understood to be concerned about the direction of the club and its identity.
The Junior Warriors are on a run of four wins from their last five games and are fourth on the under-20s table.
Elliott has named the side originally picked to play Manly for Sunday night's game against the third-placed Roosters in Sydney.
Kevin Locke will start at fullback after missing last weekend's 18-16 defeat of Manly because of a hip injury.
