Campynemanthe neocaledonica is an endemic herb of New Caledonia growing up to 18 to 25 cm high distributed across the Grande Terre, from Dumbéa to Ouégoa. The species occurs in humid forest on volcano-sedimentary and ultramafic substrate at an altitude range of 500 and 1,500 m asl. C. neocaledonica is considered to be a locally common species in New Caledonia. Despite having an Area of Occupancy (AOO) and an Extent of Occurrence (EOO) equal to 64 and 4,065 km² respectively, C. neocaledonica has no apparent threat, and is not thought to approach the requirements for listing as threatened. It is listed as Least Concern (LC).

This species has a high phylogenetic importance as it is part of the family Campynemataceae which consists of two genera and four species of perennial herbaceous plants endemic to New Caledonia and Tasmania. This species should be more collected and observations compared to the identification keys. Prospections at Roches de la Ouaième is recommended. Genetic studies are suggested in order to facilitate species identification within this genus.
