Although less than 100 greenfinch were introduced from Europe between 1862 and 1868 they are now common throughout New Zealand in farmland shelterbelts, the edges of pine plantations and native bush and scrub fringes, orchards and gardens. In autumn and winter they form large flocks, often with other finches. 

This olive green finch has a pale heavy bill and prominent yellow on the sides of the tail and the edges of the wing. The males are a brighter olive green and their yellow markings on wing and tail are conspicuous. The females are a browner, dull olive green and their yellow markings are less conspicuous. The plumage of both sexes tends to get brighter with age. In the breeding season the male’s call is a repeated harsh drawn out 'dweez' (like a long tailed cuckoo call). Other common calls are a pleasant twittering 'chichichichichit-teu, teu, teu, teu' and a rising 'tsooeet'. 

Greenfinches feed mainly on seeds (maize, cereals, oilseed rape, brassicas, linseed, sunflowers, peas, hops, redroot, chickweed, storksbill, thistles and pine) supplemented with fruit buds and a few invertebrates. 

Breeding is between October and March and two clutches a year are laid. A largish, untidy nest of twigs, grasses, moss, rootlets and wool lined with finer material and wool is built in a fork towards the top of a small shrub, tree or gorse bush or in the top of a spreading branch of a large conifer or oak. A clutch of 3-6 pale blue to light grey eggs with scattered brown spots and blotches is incubated by the female for 11-15 days. She is fed on the nest by the male.  Both parents feed the young by regurgitation during the fledgling period of 13-17 days.

Greenfinches are regularly seen and heard on Tiritiri Matangi Island.
