"This is a case of us picking the side we think will give us the best chance of winning against the Raiders," Iro said. "Pita has been in good form since coming back into the side and deserves the opportunity and we wanted to use Feleti at six.
"We had to make some changes. We have to do something about trying to get a much improved performance from the team in front of our members. It's also a special day with Lucky playing his last game before he retires."
Micheal Luck will play his last game of rugby league on Sunday before taking up a development role with the Cowboys next season and the club hope to send him out the appropriate way. It will also double as his 150th match for the club but they will need to improve significantly if they are to come close to winning.
It's not something they have done for seven games - the club's equal-worst losing streak - but they welcome back skipper Simon Mannering who has been absent for the last five games with an ankle injury.
Mateo, who will make his 52nd consecutive appearance for the club, will team up with Godinet in the halves and centre Konrad Hurrell is back in the starting line-up for his 17th game in his rookie season. Ben Matulino, a late inclusion on the bench against the Dragons, starts in the front row with Jacob Lillyman.
A decision on the final make-up of the Warriors' bench wouldn't be confirmed until just before kick-off on Sunday.
