The poll commissioned by French television found that 66 percent of eligible voters plan to vote against independence in the referendum on 4 November.
The poll, which was carried out by Harris Interactive, involved just over 1,000 phone interviews over ten days in September and has a margin of error between 1.4 to 3.1 points.
After a 20-year phase of decolonisation under the Noumea Accord, voters will be asked whether New Caledonia should assume full sovereignty, which means taking full control over defence, justice, policing, monetary policy and foreign affairs.
