A New Caledonian delegation is expected to head to the UN this month for further discussions about the decolonisation process as an independence referendum is due to be held by November next year.
Issues to be resolved include the electoral rolls which restrict voting rights to long-term residents.
In 2014, the UN sent experts to Noumea to observe the work of the commissions tasked with vetting the rolls' accuracy.
In an interview with the territory's daily newspaper, a leading member of the pro-independence Caledonian Union Mickael Forrest warned that the vote would not be fair if the electoral roll was not transparent and credible.
Mr Forrest said he hoped to push for guarantees to give New Caledonians an inalienable right to benefit from their natural resources.
