Brett Finch has decided not to renew his Wigan contract and will return home to Australia at the end of the current Stobart Super League season.
The 30-year-old joined the Warriors before the beginning of the 2011 season on a two-year deal from Melbourne Storm and has impressed at stand-off.
He had to wait to make his debut due to a neck injury but flourished in his first season in England, where he helped the club lift the Carnegie Challenge Cup last season.
"The Wigan club has been fantastic to me and I felt that it was important to sort out my future now so that everyone knew the situation and so that the club could start to make other plans," he said.
"There are a number of options back home that I find attractive and my life after footy needs to be given consideration. I have thoroughly enjoyed my time in England and to play for a club like Wigan has been a dream.
"The fans have treated me so well and I will be eternally grateful to them for making me feel so welcome. I want to finish this season strongly as I am part of a special team and feel that we have every chance of winning more trophies."
Finch has scored 13 tries in 47 appearances with the Warriors and head coach Shaun Wane admitted losing the Australian is a massive blow.
"It has been a pleasure to coach Brett this season and he has contributed greatly in making my first year as a head coach so enjoyable.
"I know his character and he will be trying his very best for Wigan until the last second of this season. Although I am sad that he has chosen to move on, I understand completely his reasons for doing so."
