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.

Wide-angled shrub with long pale twigs that are square in cross-section bearing small pale green oval leaves that are paler underneath and bright orange fruit hanging on a long stalk. Bark pale, smooth. Leaves dotted, 6-20mm long by 4-15mm wide. Flowers white, with many projecting filaments from the centre.
Endemic. North, South and Stewart Islands from near Kaitaia (Mangamuka) south but generally scarce in Northland and Auckland.
Coastal to montane forest and shrubland. Often a conspicuous component of the understorey of lowland Podocarp riparian forest but also an frequent component of grey scrub in some parts of the South Island. Unless flowering or fruiting Neomyrtus is often overlooked or mistaken for the superficially similar Lophomyrtus obcordata with which it often grows.
Shrub or small tree up to 8 m tall. Trunk slender, c.0.1 m dbh. Bark pale-grey to almost silvery, chartaceous, flaking in small irregular shards. Branches few to many, upright to spreading, often openly branched. Branchlets glabrous, 4-angled, rather brittle, either sparse and so openly branched or densely and then compactly interwoven. Brachyblasts usually sparingly leafy except toward actively growing apices. Leaves opposite, coriaceous, glandular punctate, oil glands colourless, leaf lamina and petiole decurrent with branchlet; petioles 3-6 mm long, somewhat brittle; lamina 6-15(-20) × 4-10(-15) mm, obovate-oblong to obovate, adaxially glabrous, silvery green, pale green to yellow-green, red to purple-black spotted, abaxially pale silvery green to white, glabrescent (initially finely hairy, hairs sericeous, ± finely appressed, caducous). Flowers 5-merous,in axillary, usually solitary (rarely paired) monads, borne on slender, 10-15(-20) mm long pedicels. Hypanthium subturbinate, not extending beyond ovary summit, calyx lobes 5, persistent, deltoid, spreading. Petals 5-8(-10) × 6-9 mm, orbicular, white, margins entire to slightly irregular, oil glands colourless. Stamens 40-60(-80), free, in 3-4 (or more) weakly defined whorls, filaments 5-9 mm long, anthers cream, basifixed, latrorse. Ovary unilocular, weakly septate, ovules borne on 2 parietal placentas. Style 8-10 mm long, slender, white, stigma capitate, scarcely dilated. Fruit a broadly ovoid, yellow, orange or red 6-8 mm long berry. Seeds 1-7(-11) varying in shape depending on number of seeds present per berry, mostly reniform, 1.5-2.5 mm diameter, testa brown, glossy smooth and very hard.
November - April
February - June
Easily grown from fresh seed. Can also be grown from semi-hardwood and hardwood cuttings though the strike rate can be variable. Neomyrtus is an attractive and remarkably hard shrub that does well when planted in a semi-shaded site, in a free draining, moist, fertile soil enriched with leaf litter and compost. It is however, rather drought tolerant and can (once established) be grown in high light situations. It is surprisingly drought tolerant. On account of its conspicuous flowers and colourful berries it is a very attractive plant that is well worth growing. Neomyrtus is, however, rarely available from garden centres.
Myrtle Rust (Austropuccinia psidii) is an invasive fungus which poses a serious risk to this species - learn more myrtlerust.org.nz
