Distribution
Endemic. From Clarence to Puhipuhi Rivers, South Marlborough.
Habitat
Coastal and inland lowland, usually confined to steep rocky or stony sites, rock faces and slopes.
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
Pachystegia minor is probably very local in its distribution, and many of the more accessible populations are often damaged by browsing animals. Some populations are at risk from roads, fire and the spread of weeds such as gorse (Ulex europaeus).
