Sophora tetraptera is a dicotyledonous endemic tree that sometimes has several trunks. It can grow up to 15 m tall. It is naturally occurring in the eastern North Island from East Cape south to the Wairarapa, extending west toward Taihape, lake Taupo and along the Waikato river to about LakeKarapiro.
