Detailed description
Evergreen tree up to 35 m tall. Trunk straight, 1.2-2 m diam., with buttressed base. Bark smooth, dark brown. Branches erect to spreading, slender to moderately robust. Young branchlets, leaves and inflorescences finely pubescent, hairs simple, pale golden. Foliage opposite to sub-opposite, simple, somewhat leathery when mature. Petioles (6-)8(-12) mm. Leaves (30-)40-80(-95) x (8-)11-16(-40) mm, narrowly to broadly lanceolate sometimes elliptic, yellow-green to green, glabrous when mature, undersides glaucous. margins entire, and undulate, apex acute to acuminate. Inflorescences, an erect, axillary panicle up to 100 mm long. Flowers sexually perfect, 2-4 mm diam, pale green, perianth cleft into 6 segments, ovate-oblong, stamens 12. Fruit a pendulous, ellipsoid to ovoid drupe (20-)30(-38) x (9-)12(-18) mm, 1-seeded, pericarp fleshy, dark purple-black when ripe, glaucous or shiny.
Similar taxa
A very distinct species. The green to greenish-yellow, narrow, entire, willow-like leaves with their glaucous undersides, and large plum-like, dark purple, pendulous drupes serve to immediately distinguish this from all other indigenous trees and shrubs. Some northern and northern offshore island populations differ (in some cases markedly) by their much broader, sometimes slightly bullate dark-green leaves.
Distribution
Endemic. Common throughout the North Island. In the South Island common from Cape Farewell east through the Marlborough Sounds. Extending south of there only in the east where it almost reaches Kaikoura (the southern limit is just north of the main town).
Habitat
Major canopy dominant in the lowland and lower montane forests of the North Island and northern South island. May form pure stands but usually occurs in close association with podocarps such as rimu (Dacrydium cupressinum).
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.

Taxonomic notes
Beilschmiedea tawaroa A.E. Wright described by Wright (1984), is not upheld here because it is not ecologically distinct, there is gradation between these large-leaved variants and normal tawa (B. tawa), and because aside from leaf width there are no other consistent distinguishing characters (de Lange & Cameron 1999). Plants with B. tawaroa characters - as defined by Wright (1984) have now been found as far south as Mt Taranaki and Mahia Peninsula.

Life cycle and dispersal
Fleshy drupes are dispersed by frugivory (Thorsen et al., 2009).
Propagation technique
Easy from fresh seed. Better germination is achieved if the flesh surrounding the seed is cleaned off.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).

UPL: Obligate Upland
Rarely is a hydrophyte, almost always in uplands (non-wetlands).

Regional conservation statuses
Auckland: 2025 | Regionally Not Threatened | Qualifiers: DPS, DPT
The regional threat classification system leverages off the national assessments in the NZTCS, providing information relevant for the regional context. Auckland conservation status information is sourced from the “Conservation status of vascular plant species in Tāmaki Makaurau / Auckland” Simpkins E et al. (2025) report.
