The conservation status of N. gantungensis has not been formally assessed for the IUCN Red List, but the describing authors suggested it be considered Critically Endangered based on the IUCN criteria, due to its localised distribution and small population size. The natural habitat of this species remains, for the most part, untouched by human activity, although a radio repeater tower and a small building are present near the summit. Mount Gantung lies within the Mount Mantalingajan protected area, but large scale commercial mining operations have nonetheless continued on a nearby summit.
