Polyosma leratii is an endemic shrub or tree from New Caledonia, where it has scattered, but quite wide distribution across the northern half of Grande Terre. It occurs in dense humid forest on volcano-sedimentary substrate from 400 to 1,040 m asl. This species does not seem to be threatened at the moment. Its extent of occurrence (EOO) and area of occupancy (AOO) are estimated at 2,164 and 64 km², respectively. Therefore, P. leratii is listed as Least Concern (LC).
