Cyphokentia macrostachya is a solitary, understory to canopy tree palm tree with a disjointed distribution in south and central part of Grande Terre in New Caledonia. Cyphokentia macrostachya occurs in wet forests on soils derived from either schistose or ultramafic rocks from 170-800m asl. In the south, C. macrostachya is very abundant in Parc de la Rivière Bleue where it the dominant palm species in primary forest at 150-200m asl. With an extent of occurrence and area of occupancy respectively equal to 5,544 and 68 km² and the fact that big populations occur in protected areas, Cyphokentia macrostachya qualifies as Least Concern (LC).
