The congress is headquartered at 1 Boulevard Vauban in downtown Noumea.

Local media in New Caledonia refer to the congress as "boulevard Vauban" when referencing it.

Members are elected proportionally based on the partisan makeup of all three assemblies of the provinces of New Caledonia with a 5% threshold.

[1] The political parties, aside from naturally being split based on socioeconomic ideological differences, are split along hard-line stances on possible New Caledonian independence from France.

Both independentists and its opponents subscribe to various socioeconomic ideologies so the difference of opinion is usually rooted in favouring either Kanak nationalism, New Caledonian separatism and independence as opposed to French nationalism and New Caledonian regionalism.
