The French High Commissioner Laurent Provost said New Caledonia must remain Covid-19 free which means that all arrivals would be subject to the compulsory government-run two-week quarantine.
Provost said about 260 people would come from Paris, such as members of the highest administrative court, government officials and magistrates.
He said there would also be international experts from the United Nations and observers from the Pacific Islands Forum.
However, it is not immediately clear how they could travel, given the cut in the region's air links.
New Caledonian carrier Aircalin only operates flights from Sydney, Tokyo and Wallis and Futuna.
Like in the previous referendum in 2018, the control commission overseeing the plebiscite will be headed by Patrick Lamy.
Just over 180,000 people are entitled to vote, which is about 6,000 more than in 2018.
In the last referendum, just under 57 percent voted for the status quo.
