Distribution
Indigenous. Common from Te Paki south of Auckland. Local south of there until the Wairarapa and Wellington where it is very common. South Island common in Nelson, Marlborough and Westland. Also known from single records from Stewart (2000) and Rekohu (Chatham Island) (2008). Also in eastern Australia and Tasmania
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.
