Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W.

Brief description
Locally very common small shrub to 1m tall with hairy twigs bearing masses of small narrow wrinkled leaves and clusters of white flowers. Leaves 5-10mm long by 1-2mm wide, margins inrolled to almost cover the underside. Fruit dry, small.
Distribution
Endemic. Three Kings, North and South Islands. In the South Island generally scarce reaching its southern limit at Eyrewell Forest, Canterbury; south of Auckland it is mainly east of main ranges in North Island.
Habitat
Usually coastal and lowland open shrublands, gumland scrub and in sand country. Also in rocky headlands, gravel river terraces. Occasionally found well inland in montane situations. A species virtually confined to successional vegetation types
Flower colours
White, Yellow
Propagation technique
Difficult. Can be grown from semi-hardwood cuttings and seed but seed is hard to germinate. The best results seem to be from cuttings rooted in untreated sawdust. Once plants are established they grow very well and make an attractive flowering shrub for an open, sunny post. It does best in nutrient-poor, well-drained soil
Etymology
pomaderris: Lid skin
amoena: From the Latin amoenus ‘delightful, beautiful, pleasing’
Taxonomic notes
The New Zealand plant has been treated as P. phylicifolia Link, P. phylicifolia var. ericifolia and P. ericifolia. However, the types of these taxa are from Australia, and studies have shown that those types do not match the New Zealand plant. The New Zealand plant is apparently endemic. nrDNA ITS sequences confirm that it is not closely related to P. phylicifolia.
