Syn: C. sulcata var. alpina (Silba 1986).
New Caledonia, at elevations of 950 to 1,350 m in maquis on ultramafic substrates in the southern massif on New Caledonia. It has an estimated extent of occurrence of 257 km2 in more than 10 locations. As most populations are in protected areas, the major threat to the species is wildfire (Thomas 2009).
Zone 10 (cold hardiness limit between -1°C and +4.4°C) (Bannister and Neuner 2001).
Most subpopulations are located in Montagne des Sources and Mt. Humboldt Botanical Reserve, and at least one has been affected by recreational trail construction, but Thomas (2009) does not specify where.
The epithet neocaledonica refers to New Caledonia; this and C. sulcata are the only species of Callitris occurring there.
