Former All Black Byron Kelleher has been found guilty of domestic violence and fined 200 (NZ$297) by a French court.
French media reports say the former Toulouse player appeared in the Correctional Court of Toulouse on Thursday (local time) charged with "domestic violence against his partner" in June.
The 40-year-old was accused of abusing her after a night out.
Kelleher's lawyer, Master Corinne Laporte, described the incident as a "lovers' dispute".
The halfback played for the All Blacks 57 times between 1999 and 2007.
In 2009 he was involved in a brawl in Toulouse after a car crash while driving drunk, and he was also arrested in 2013 for alleged drink-driving in Bordeaux.
He is the third former All Black to face the law in France in recent weeks, after Dan Carter was caught drink-driving in Paris and Ali Williams was charged with buying cocaine outside a Paris nightclub.
