 The Orokaiva occupied what is now Oro Province and the periphery of the area they inhabited was marked by the Owen Stanley Range in the south, German New Guinea in the west, and the Hydrographers Range in the south.The rite of passage through which a child becomes an adult in Orokaiva society is largely exceptional among the peoples of Papua New Guinea, involving both girls and boys.It begins with masked figures, dressed in bird feathers and pigs' tusks and representing ancestral spirits, entering the village as if on a hunt, and herding up the children who are to go through initiation.
