As of my last knowledge update in October 2021, New Caledonia had not gained independence from France. The territory held a referendum on independence in 2018, with approximately 43.6% voting in favor of independence and 56.4% voting against it. A second referendum took place in 2020, which resulted in an even smaller percentage (about 47.3%) voting for independence.
The process of independence and self-determination for New Caledonia is ongoing, with provisions for additional referendums in the coming years. However, as of late 2021, New Caledonia remained a French special collectivity.
For the most current status, I would advise checking the latest news sources or official updates, as any developments after October 2021 would not be reflected in my information.
