Crimson juice of the berry used as ink (Colenso 1868a).

Kōkihi is a red berry, but is not edible. Used to see the children stain their faces with it (Tunuku Karetai, to Beattie. MS 582/E/11, Hocken Archives, Dunedin)

"It has a red berry from which a red dye could be made, but the dye was not permanent, only lasting a certain time. The berries were merely soaked in water and squeezed to make the dye. In recent times the berries have ben used to make a red ink for the Māori children to rule their school lessons."

"A good many years ago some women tried the experiment of being tattooed with the red juice from the kokihi berries. One of my oldest informants had seen some of them. The red effect was startling and looked well but did not last, fading away after a number of years" (Beattie 1994)
