New Caledonia's USTKE union says it will march on May Day to support the continued use of the Kanak flag and to fight against the disadvanatges felt by young Kanaks.
The union's vice-president, Alphonse Pujapujane, says the Kanak flag won't ever be lowered because the history of the Kanak people cannot be ignored.
He says in New Caledonia France has maybe the chance to have one successful decolonisation.
The call comes after four governments collapsed this year amid a dispute over which flag should be chosen, with the last three collapses brought about a demand that a new flag be adopted.
The USTKE leader, Marie-Pierre Goyetche, warns that poor school results of Kanaks and subsequent joblessness have created a situation of revolt, which will explode in a country that some call El Dorado.
