I have never seen a Maori equivalent of a a lei. I suspect that climate may have played a part in that. Before the arrival of Europeans, there were few "flowers" as such here, certainly not with the spectacular blossoms seen in Hawaiian lei. It would take some very nimble fingers to be able to fashion any sort of garland from native flowers. The nearest equivalent was the giving of cloaks, made from different materials according to the stature of the recipient. Kiwi feather cloaks are still made from time to time, as the Department of Conservation often gives dead specimens of culturally important fauna to local Maori for traditional use. Cook Island Maori do make lei, though I'm not sure what they call them. They also give one blossom for the recipient to place above the ear.
