He also stated that Leigh had fought off competition from Super League clubs for the player’s signature.
The 35-year-old former Kiwi international forward has signed a one-year deal, with the option of a second, with the Centurions.
“It is a positive sign that the club has grown in reputation both on and off the field and that word of mouth has reached foreign shores at the most elite level.
“Fui is a world-class player who will not only bring profile to our club off the field but a huge presence and class on the field.
“I am looking forward to coaching Fui and helping him to enjoy and flourish in his time within our Centurions family.”
Leigh head of rugby Derek Beaumont also confirmed that Super League clubs had been rivals to sign Moimoi.
“With the assistance of those mentioned we were able to convince Fui that his best option was to come and be part of the family at Leigh Centurions, where he can be a part of history in achieving something special.
“He will be a revelation in our division and will grab some big headlines. The sheer story attracts bigger headlines in itself and our fans will embrace him, making him a local cult hero.
“He has bought into that and feels challenged by it. It is a great way for him to settle into the English game, where he can gauge where it’s at from a unique family surrounding.
“He is already familiar with the facilities we have which had a big influence on his decision to join us and is aware of the local Tongans we have in town in Tau Liku and Lee Hansen.
“We are also looking forward to welcoming Fui’s son into our family and making him feel valued and happy during his time over here.”
