The 25-year-old Prop Forward joins the Centurions from Gold Coast Titans in the NRL.
Leigh Centurions Head Coach Neil Jukes said: “Paterika is an outstanding signing for our Club. He is an unbelievably powerful player and his explosive, direct running style will be really instrumental for our team next year.
“I have no doubt whatsoever that the Leigh Centurions fans are going to really enjoy watching Paterika play for our Club and showcasing his ability.
“From speaking to him it is clear that Paterika is a highly motivated player who is really looking forward to coming here and playing his best footy and the Coaching Staff will 100 percent support him in that objective.
“Again, I’d like to thank (Head Of Rugby) Keiron (Cunningham) for all the work he has done getting this one over the line. We have no doubt that Paterika is going to be a huge fans’ favourite.”
Leigh Centurions Owner Derek Beaumont said: “I am really excited by this signing and have been since Kez (Keiron Cunningham) mentioned him to me.
“The biggest statement this club made when I got back involved was signing a man that good they named him twice, and he was a massive asset to this club and a fans’ favourite.
“I hope that the fans get the same excitement from Patty, especially given he is at the early part of his career and has lots in front of him. I can’t wait to see him get going for us.”
