It's not true. Overseas parts of France are fully integrated in the republic, and citizens there have the same rights as in the mainland. There's no distinction between "settlers" and "natives" from a legal point of view (the economic picture is a bit different). There have been referendums in New Caledonia about independance and people there still want to be part of France.
To be faire, I don't even understand how New Caledonia or French Polynesia (where people have full representation in congress) can be on the non-self-governing list of the UN when Puerto Rico (where citizens don't have a seat in the house, senate or electoral college) isn't.
