The Baining are one of the two major cultural groups living on the island of New Britain. Of the many subgroups that constitute the Baining, the Uramot and the Kairak living in the center of the Gazelle Peninsula were historically the only two to practice night dances with barkcloth masks, the most complex portable object that they created.

There are two primary types of Baining night dance mask: the kavat, which is a helmet mask, and the vungvung, which is a massive mask with at least one long, axial bamboo pole travelling its length. Both types are relatively lightweight, in large part due to being constructed from pounded bark cloth laid out over a bamboo-cane frame. Raffia is used to lash the frame together and to attach the various components of larger masks to one another. These masks are made exclusively by men and are performed during fire dances, which serve as initiation rituals between three distinct age-initiation tiers. Children begin by creating small lingan barkcloth headdresses, young men create kavat, and only the most skilled men create vungvung.
