UNESCO will have meeting in New Zealand later this month to discuss applications of sites seeking world heritage status.
France is to make two submissions to the conference in Christchurch for two New Caledonian sites.
They are the 17th century military architecture of the Marquis de Vauban and the lagoons of New Caledonia.
A total of 45 submissions from 39 countries are being made for registration.
Media reports say UNESCO has not released the list of candidate sites.
Currently 830 sites of special natural or cultural importance enjoy protection under a 1972 UNESCO convention.
