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.

Red List Criteria
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.
