About

Pomaderris kumeraho, or kūmarahou, also known as gumdigger's soap and golden tainui, is a plant endemic to the North Island of New Zealand. The name kūmarahou originates from Māori.

Where it grows

Pomaderris kumeraho is endemic to New Zealand, found in the north the North Island, as far south at the Kawhia Harbour and the northern Bay of Plenty. The plant grows in coastal and lowland areas, typically found near roadsides or in regenerating bush. As it is able to grow in barren areas, it grows in gumlands and became associated with kauri gum diggers' fields in the north of New Zealand.
