There has been an outcry by New Caledonia's president, Harold Martin, over the way the Congress president spoke out against the visit of the Fiji regime leader, Commodore Frank Bainimarama.
Mr Martin says it is outrageous that Gerard Poadja issued a media statement purporting to be from the government.
He says this is a first in the history of New Caledonia's institutions and appears to be an attempt to manipulate public opinion.
Mr Poadja says New Caledonia has no need for the Fiji model with its suppression of fundamental rights.
Mr Poadja's party failed in its bid to get France to deny the Fiji regime leader a visa for the MSG summit.
Paris allowed him into France twice this year to allow the Commodore to look at the new planes which Fiji's flag carrier is buying.
