Kia ora Charlotte ,my name is Graeme Atkins and I work for DoC at the East Cape .I can confirm what Peter and Mike have said .Several years ago an old kuia from home told me that they regularly ate the pods from plants. Many historical records of the species former distribution are associated with pa and kainga .She could also recall plants been used to lure tui and kaka to there demise for seasonal harvest .So it seems that plants around the whare were not just there for aesthetic purposes .In former times , in a land lacking in natural vegetable protein, ngutukaka would have been an abundant food resource to be treasured. They are delicious .
