Taulima Tautai plans to return to Australia after agreeing a departure from Wigan.
The forward was the subject of a club investigation after being convicted of drink driving on June 12 and the two parties have now agreed to go their separate ways.
"After a series of conversations with Taulima, it was mutually decided that he will leave the club with immediate effect after five years at Wigan Warriors," said executive director Kris Radlinski.
"Taulima and his family expressed their wish to return to Sydney immediately to be closer to their extended family and we have facilitated that wish. We'd like to thank Taulima for his efforts at Wigan and we wish him and his family well for the future."
The 31-year-old joined Wigan from Wakefield ahead of the 2015 season and won the Super League Grand Final with them in 2016. He missed out on selection for the 2018 showpiece.
"I would like to say that I am grateful to Wigan Warriors for the opportunity that they have given my family and I for the past five years to live out my passion of playing rugby league. After achieving great success at the Warriors I feel that the time is right for me to take my family home," he said.
"This decision has not been an easy one to make but I feel it is the right decision for my family, and I am very appreciative of the compassion shown by (chairman) Ian Lenagan and Kris Radlinski whilst we have reached this agreement."
