It is a low growing shrub reaching a height of around 2 metres.[1] This species has a divaricating habit that lasts for the life of the shrub unlike other New Zealand Sophora species which lose the divaricating habit as adult trees..[2]

The leaves of this species are usually quite small up to about 2 cm in length.[3]

Flowers are often orange though they do occur as yellow in common with most other kowhai species.[4] The seeds are black or very dark brown and may appear dark red. This contrasts with other native New Zealand species whose seeds are yellow.[4]
