Endemic. North, South, Stewart Island. The exact northern limits of Weinmannia racemosa are uncertain but probably lie somewhere along the Manukau Harbour and Hunua Ranges across the Kamai Range. North of here the distinction between Weinmannia racemosa and W. silvicola is often confused. This needs further study.
Coastal to subalpine. A widespread and common tree of disturbed habitats in coastal and lowland to montane forest, often becoming locally dominant in higher altitude montane forest in the higher ranges of the North Island and western South Island.
Tree up to 28 m tall often forming a narrowly domed canopy (but this will vary according to local conditions). Trunk up to 1.2 m diameter. Branches numerous, erect to spreading, Foliage heterophyllous. with distinct seedling, juvenile and adult leaves (reversion shoots common). Stipules caducous, 3-6 mm long, lanceolate, finely pubescent, yellow-green to pinkish. Seedling and juvenile leaves membranous to subcoriaceous, 10-60 × 10-30 mm; lamina simple to 3-lobed or 3-foliolate, ovate-elliptic to elliptic or lanceolate, apices subacute to acute, margins serrate to incised-serrate; adult leaves coriaceous, on petioles up to 20 cmm long, lamina 30-100 × 20-40 mm lamina simple, elliptic, ovate-elliptic to broad-ovate, apices obtuse to subacute, margins rather coarsely, bluntly serrate. Inflorescences in racemose; racemes 60-1140 mm long, rachises and pedicels finely, pilose-pubescent; pedicels 2-4 mm long, clustered, ascending to spreading.

Easily grown from fresh seed. Can also be grown from semi-hardwood cuttings. This is an attractive tree tolerant of a wide range of conditions and soil types though it does best in high light, and in free-draining soil. The flowers are very attractive to a range of insects and birds
