England international forward will return to the Super League with Wigan Warriors for the 2021 season.
Bateman signed for Canberra Raiders ahead of the 2019 season, and had a big impact on the NRL, after being named Dally M Second-Rower of the Year.
He has signed a four year contract with the club.
Speaking about his decision to return to the Warriors, Bateman said: “I’m very happy to be returning to Wigan on a long-term contract. On a personal level, some of the best times of my life have been in a Wigan shirt and I can’t wait to return, to play and make some more memories.
“It’s been a tough decision but to be back to Wigan, to be at home with my little girl, my Mum and the rest of my family is something I can’t wait to experience once again. I still have plenty of unfinished business with the Raiders and my focus now is to get myself back on the pitch as soon as possible and put myself in the frame for selection.”
Warriors Director of Rugby Kris Radlinski added: “Wigan are thrilled to be bringing John back to the DW Stadium.
“John is one of the best players in the world. He has the respect of players and coaches in both hemispheres and is a natural born competitor and leader.
“John is now completely focused on getting fit and returning to the Raiders squad and finishing off his adventure in Australia on the highest note possible.”
