New Caledonia's pro-independence FLNKS Movement has called for the United Nations to send a mission to observe next year's territorial election.
The polls in May are to elect three provincial assemblies, out of which the Congress will be formed that is tasked with overseeing the last phase of the 1998 Noumea Accord on greater autonomy.
The Congress can decide if there is to be an independence referendum.
Under the Accord, voting next year is restricted to those already on the roll by 1998.
The FLNKS has questioned the validity of the election, given that according to its information 3,000 voters have been listed who were not born in New Caledonia.
It says at the same time 1,900 Kanak voters have been excluded.
An FLNKS leader, Roch Wamytan, says the issue was raised in Paris earlier this month, adding it's not a question of shutting out anybody but to adhere to the text of the Accord
