Former Warriors coach Matthew Elliott says the Auckland club makes good players worse.

The Warriors will miss out on the finals for the sixth successive season after losing their last six NRL matches.

Elliott was Warriors coach from 2013 until his departure after just five rounds of the 2014 season following a 37-6 loss at Cronulla.

"Bad players go to the Melbourne Storm and turn into good players. I see good players go to the Warriors, and get worse," Elliott told Radio Sport as one of four coaches who've failed to brings finals footy to Mt Smart since a Grand Final appearance in 2011.

"That isn't about their ability, that isn't about the quality of the person, it's about the environment, and the environment needs to change.

"Changing the environment is awkward, and you're going to have to go through resistance. That's wasn't something that in my experience there, that was embraced."

Marquee signings like Kieran Foran, Roger Tuivasa-Sheck, Issac Luke and Sam Tomkins haven't reached the heights they achieved while playing for their former clubs as coach Stephen Kearney begins to overhaul the squad after another disappointing year.

Elliott said the behaviour of the Warriors wasn't good enough as far as professional rugby league goes.

"You don't need to be a rocket scientist to know that something needs to change with the culture of the Warriors," he added.

"What change requires is going through some complexity and some resistance, and if you're not prepared to go through that and you can't embrace that, it's not going to change."
