French club offers Barrett biggest rugby deal ever
The report stated that a French Top 14 club are willing to pay $3.4 million a year for Barrett's services.
The sum would see Barrett leapfrog Daniel Carter as rugby biggest earner. Carter currently pulls in $2.83m a year with French club Racing 92.
Barrett's agent Warren Alcock refused to make comment when contacted by Daily Telegraph.
The 26-year-old Barrett is off contract after next year's World Cup, and the new proposed deal would see him make upwards of $10m over three years.
Barrett is set to play his 100th Super Rugby match against the Crusaders on Saturday.
During his side's week two matchup against the Bulls, the 62-test All Black became just the fourth player in Super Rugby history to notch 1000 points.
