The species seems to have a very restricted distribution. Prof. Kjell Ivar Flatberg (a world expert on the genus) visited the Islands in 2010 and found a couple of new, but still very small subpopulations. The species is listed as Vulnerable under criterion D2 because of the small area of occupancy, small number of known locations and because the species grows in or new rivers which are sensitive environments which can be very quickly impacted by human activities, especially pollution from agricultural and mining activities.
The species could potentially be listed as Endangered under criterion D because of the estimated small size of the known population, however, this is probably an under-estimate as the species may occur in other sites, hence such a listing seems overly precautionary.
This species is confined to only a few localities on the main island of New Caledonia; it has been recorded from the Plateau de Dogny, Forêt de Tao and from Mt Panie.
The island was visited in 2010 by Professor Dr Kjell Ivar Flatberg (a world expert on the genus Sphagnum) and he recorded the species at two different locations. The largest location is Mt Panie where he found the taxon at three sites close to each other, probably the same area as where Z. Iwatsuki originally found it, but at somewhat lower altitudes. At the first of these sites on Mt Panie the species was on the southern side of a small river (20.56105° S, 164.78720° E) at ca. 500 m asl and it had a relatively large subpopulation size. The other two sites on Mt Panie were along small rivulets on percolated stones and boulders and was rather sparse at each site (20.55982° S, 164.78487° E), at ca. 550 m asl and (20.56070° S, 164.78160° E), at ca. 530 m asl.
He also found Sphagnum novo-caledoniae on the Plateau de Dogny (21.61798° S, 165.88229° E) at ca. 930 m asl. However, this site was quite small and facing a rivulet border growing on a vertical wall of mixed silt and sand, with surprisingly no peat.

|Population:||The population is estimated to number about 100 mature individuals and is scarce to relatively common in the places where it is found. The population trend is not known.|
|Habitat and Ecology:||Grows on rocks and silt, in and along small streams in shaded forest between 530 m and 1,200 m.|
|Major Threat(s):||The main potential threat is pollution of stream water from either mining or agricultural activities|
The species is not known to occur in any protected areas and no conservation measures are in place for it at all.
