Cunonia bullata is an endemic shrub of the south part of Grande Terre in New Caledonia. It is found in shrubland at high altitude on ultramafic substrate. This species does not seem directly threatened because of its altitudinal habitat and the fact it may be abundant. Its area of occupancy (AOO) being estimated to 36 km², Cunonia bullata is considered Near Threatened (NT) close to VU D2 because of its reduced number of subpopulations and narrow AOO.
