Konrad Hurrell has paid for some mixed form by being dropped to the NSW Cup side for Saturday's Anzac Day match against the Titans at Mt Smart Stadium.
The centre struggled with injury early in the season and, while he did some good things in the 28-24 defeat to the Cowboys last weekend, made crucial errors that put his side under pressure.
David Fusitu'a, who has played most of his NRL career on the wing and who has been in good form for the NSW Cup side, will start at centre in his place.
Back rower Raymond Faitala-Mariner will also become the Warriors' 200th NRL player while veteran prop Sam Rapira will have his first outing of his 10th and final season. The pair have both been named on the bench and come in for Albert Vete and Dominique Peyroux.
"I had to make the changes," coach Andrew McFadden said. "With Konrad, he's been working really hard but I feel it has effected his performances. He has been doing some good things and there are some things he needs to work on. He's aware of that. And David Fusitu'a's form in the NSW Cup side has been too good to ignore. He's well and truly earned his spot there.
"No one is safe. We want performances on the field so we need competition [for spots] to guarantee that. When people slip up, I need to make changes. The players are aware of that and that drives performance.
"Errors are really hurting us at the moment and I need to keep the players accountable to that."
Faitala-Mariner played for the Junior Warriors in the 2013 NYC grand final before joining the club's fulltime NRL squad last year. He was a fixture of the Warriors' NSW Cup side last season and figured in the club's NRL trials against the Titans and Penrith in February.
He has been on the cusp of selection this season and last weekend travelled to Townsville as the NRL side's 18th man.
Rapira has played three games for the NSW Cup side since recovering from a hamstring injury. He moves to the English Super League next year.
"Sam would have been picked in round one and he's really starting to hit some form," McFadden said. "We're changing up the dynamic of our bench. Dam has done well but need to play some footy."
The club's first-ever Anzac Day match at home launches a programme of five games in five cities on a day New Zealanders and Australians unite to commemorate the 100th anniversary of Gallipoli.
