The New Zealand Rugby Union has cut former All Blacks winger Zac Guildford loose, terminating his contract.
New Zealand Rugby general manager rugby Neil Sorensen said it was decided to terminate the contract immediately following discussions with the Crusaders and Guildford.
Guildford was contracted until the end of the Super Rugby season, but is now free to take up a new contract he has signed with Clermont Auvergne in France.
Sorensen said on Thursday that Guildford was talented but troubled, and had struggled to meet the commitments made to keep on top of personal issues.
Guildford has been involved in several alcohol-fuelled incidents in past years and admitted in 2013 that he was an alcoholic. He spent time at a rehabilitation centre to try and overcome his problems.
In 2011, the union banned Guildford for four games after a drunken rampage while in the Cook Islands.
In 2009, Guildford's father Robert died in a Tokyo grandstand while watching his son play for New Zealand in the final of the World Under-20 Rugby Championship.
New Zealand Rugby chief executive Steve Tew said he couldn't see Guildford returning to the All Blacks.
