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 kōwhai species.[4] The seeds are black or very dark brown and may appear dark red. This contrasts with other native New Zealand Sophora species whose seeds are yellow.[4]
