His hand was forced following the side's dreadful 37-6 defeat to the Sharks on Saturday which was followed by reports in Australian media that he would be axed by the club.
The club confirmed Elliott's resignation this morning on Twitter. He will be replaced by assistant coach Andrew McFadden.
"I have learned a lot from Matt and am saddened that he has made this decision. It speaks volumes of his character and integrity and I personally wish him well," Warriors chairman Bill Wavish said.
The heat was certainly being applied to Elliott, and it's known he had some short-term targets to achieve to keep the owners happy.
"Tough day at the office @NZWarriors ... however definitely some questions to be answered," owner Eric Watson said on Twitter yesterday.
Watson and co-owner Owen Glenn want to turn the Warriors into the "best single sporting franchise in Australasia"and have invested heavily to try to achieve that. Glenn, in particular, is said to be decisive and doesn't stand for mediocrity.
It didn't take them long to dispense with Brian McClennan, who was dismissed before the end of his first season in charge in 2012.
Top coaches have the right chemistry with their players and there have been rumblings of discontent within the Warriors' playing group.
Elliott's not the one making the mistakes on the park but he is the most accountable. The Warriors' attitude is a big concern - there is a huge difference between their best and worst performances - and that often comes back to culture.
"That's a legitimate question and one that needs to be asked," Elliott told the Herald immediately after the defeat to the Sharks when asked if he felt his players played for him.
The Warriors have been inconsistent throughout their history but seemed to be turning a corner under Ivan Cleary. They went through some dry patches when he was coach but often their defeats were close.
Elliott has also endured some narrow losses but also witnessed some heavy defeats, and often against middling sides, like the 62-6 hiding dished out by Cleary's Panthers and the 28-4 defeat to the Sharks last season. Their performances in their three defeats this year have been inept and they have the worst defensive record in the NRL.
Elliott's contract was to expire at the end of the season and Wigan coach Shaun Wane has repeatedly been linked with the Warriors - something strenuously denied by the club.
They are one of the best resourced clubs in the NRL, with millions having been spent since 2012 on facilities and support staff, but the only true measure is what happens on the field. And that was Elliott's responsibility.
