Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Threats
As far as is known this species has always been confined to a small portion of the Dunstan Range above the Kawarau River, near Cromwell. At present just the one population is known (and in fact this may be the same population as that discovered originally by John Buchanan and James Hector). That population has been regularly monitored for the greater part of 30 years, and seems to be stable. Nevertheless because the species is known from just the one site, within an area of < 1 ha it qualifies as Nationally Critical.
