Following great disruption and depopulation in the 19th century, practically nothing remains of the cultures of northern and southern Vanuatu. The central islands of the archipelago—the large island of Malakula, Pentecost (Pentecôte) to the northeast, and Ambrym to the east—are the most significant artistically. Although this group comprises several distinct style areas, it shares certain cultural characteristics. The major socioreligious institution of Vanuatu was the graded society, a hierarchical system of ceremonies performed by men and women to attain greater prestige. The number of grades and their names, as well as the name of the system itself, varied from place to place, but in all areas the grade ceremonies included the sacrifice of pigs or boars, feast giving, and the production of physical memorials. The memorial sculpture was prescribed in form and was made in wood or from the trunks of tree fern, an easily worked material resembling compacted pine needles.

On the northeastern Malakula coast and on some small neighbouring islands, large dance grounds surrounded by stone monoliths and dolmens were set up at stages of the grade ceremonies. The stones were covered by simple shelters with the main wood post carved into human form. The head on such figures was half the height of the whole post; it was shaped like an elongated diamond and had circular eyes, a long nose, and a crescent-shaped mouth. These posts supported a ridgepole consisting of a tree trunk, the spreading roots of which were roughly shaped into the likeness of a hawk. The same image was also used for the ridgepole of ceremonial houses and on huge ceremonial banners of bark and bamboo. The bodies of these hawks are shaped like diamonds, their wings are triangular, and their heads resemble the stylized carvings of birds made for canoe prows.

The eastern coast of Malakula, Pentecost Island, and Ambrym Island together form another style area. The slit gongs of Ambrym are the largest and most elaborately carved of any in Vanuatu. As in all parts of Vanuatu where they were used, the Ambrym slit gongs were set around the dance grounds, standing upright or at a slight angle. They are found in two main forms. In the north of the island, the gongs terminate in huge three-dimensional heads with puny arms below them. The forehead and the back of the head are scored with deep cross-hatching; the eyebrows are arched, with disk-shaped eyes filling the space below them; and the concave oval facial plane is almost filled by a massive carved nose. The slit gongs of western Ambrym, on the other hand, taper upward to an even greater height and have two to three faces in the elongated-diamond style carved on them in relief. The northern Ambrym style of face is also found on the fern-wood figures made for grade ceremonies. These figures were sometimes of humans, with oversize heads, globular torsos, and slight limbs, but they could also have human heads with zoomorphic bodies. All were originally coated with clay and painted with vivid polychrome body-painting designs. Masks from the area include one type carved in hardwood that was common to both Ambrym and southern Pentecost; it has a bulging forehead, prominent cheeks, pierced eyes, a grinning mouth, and a huge, arched nose. Brilliantly coloured masks made from softwood were apparently usually comedic in intent.

The southern coastal peoples of Malakula, including some in the southern mountains, employed a wealth of objects not only for grade ceremonies but also for farming and initiation rituals. A major technique involved the use of a vegetable compound moistened with coconut milk to model heads or oversize seated figures over coconuts, bamboo frames, or other hard materials. The skulls of important men were also covered with the compound and then mounted on bodies of fern wood and bamboo adorned with beaded armlets and the tusks of sacrificed pigs. Smaller heads were sometimes fastened to the shoulders of these figures. All the modeled works were fully painted, with a great use of deep blue, white, red, and yellow. Most of the modeled heads, figures, and masks have boars’ tusks protruding from their mouths. Helmet masks are janiform or have quadruple faces or are surmounted with seated figures. Carving was less significant in the southern areas than in the rest of Vanuatu, and figures were somewhat flat and squat, with broad faces indicated only by a summary series of horizontal grooves.

In the mountainous northern region, sculpture appears to have been confined to large heads in fern wood and small janiform heads on spear shafts. These were carved in a powerful geometric style; the deeply cut, sharp-edged ridges and hemispheres approach total abstraction.
