All Blacks legend backs France WC bid?
Carter retired from international rugby in 2015 after helping New Zealand win a second successive World Cup and is the leading points scorer in Test history.
The 35-year-old subsequently joined Paris-based Racing 92 for the 2015-16 campaign and led the club to the Top 14 title in his first season.
According to the French rugby president Bernard Laporte, the Racing 92 flyhalf is expected to fully support the France 2023 campaign.
"It's not sewn up but it's looking good. He really wants to," Laporte said of Carter's proposed involvement at the September 25 bid presentation in London.
France, who last hosted the World Cup in 2007, will face competition from Ireland and South Africa for the right to stage the 2023 tournament.
The winning bid will be announced on November 15.
