It is endemic to New Zealand and found throughout most of the country, from the Kermadec Islands to Stewart Island / Rakiura and out to the Chatham Islands, but not known from Raglan to Manawatū in the west of the North Island, except on Mount Taranaki.[1][4][5]

It grows to 0.3–1.0 metres tall, and sometimes hangs as much as 2 metres long down steep banks. It has very fine, narrow leaves, usually 1–1.5 millimetres and up to 2.5 millimetres wide. Leaf width varies through the country, with narrow, needle-like leaves in the central North Island and relatively wide leaves in the northern North Island.[1]
