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. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

A. nervosa may be confined to the South and Stewart Islands; North Island plants have greener leaves with a brownish/bronze indumentum on the abaxial (lower) surfaces and these may constitute an unnamed taxon.
Undersides of leaves often showing zigzag ‘tracks’ caused by feeding of the larvae of the ‘astelia zigzag moth’ (http://www.monarch.org.nz/monarch/wp-content/uploads/2013/04/Autumn13_03.pdf)
Fleshy berries are dispersed by frugivory (Thorsen et al., 2009).
nervosa: With conspicuous veins
