The long, narrow island of New Ireland shows three distinct style areas: the northwest, the centre, and the southeast. The first area is celebrated for its malanggan carvings and masks, which share their name with a series of religious ceremonies held primarily as funerary celebrations but also (by extension) for the validation of land claims, the establishment of subclans, and other important events. In this most elaborate style of Oceania, the usual form of the face has horizontal brows, with the deep-set eyes inlaid with bright sea-snail opercula; the nose is strongly arched and massive; and the jaws, broad horizontal rectangles, show a formidable array of serrated teeth. The fully three-dimensional figures usually have added attributes, including bird and animal forms; they often clutch frameworks of rods, which enclose them. Flat areas are pierced in intricate patterns, a technique that was probably fostered when the islanders acquired steel tools. All works were painted for fullest effect in sharply defined areas of black, white, red, and yellow; small sections of black cross-hatching and other patterns often further enhanced the design.

Malanggan carvings on poles display either individual figures or several figures stacked vertically. Freestanding carvings often illustrate mythological incidents and can be of great size. Pigs, birds, and fish are the subjects of other carvings. Seated figures used for rainmaking ceremonies were constructed from tree trunks, bamboo, and other materials; they had raised hands and were fitted with carved heads.

Some malanggan masks are almost indescribably complicated, with the basic style of carved face adorned with long vertical tusks and other protrusions, fitted with openwork side panels of birds and fish, surmounted with birds, snakes, and figures, and enclosed within a lattice of bars. Some simpler types have seminaturalistic faces.

Other malanggan carvings are horizontal panels. There are several types, including one with a fish head at each end and human figures between them, another with apertures in the middle through which men put their heads, and one with representations of the moon. One type of carving that depicted a bird struggling with a snake was sometimes mounted on the head of a figure.

In central New Ireland the primary objects of mortuary cults were carvings known as uli. These are standing figures with female breasts and male genitals; they sometimes have raised hands and may support smaller figures in front of them or on their shoulders. The head is usually large and is topped by a thin, upright crest; the eyes are inlaid with shell, the nose is hooked, and the wide mouth exposes the teeth above a triangular chin. The body of the uli, like that of the malanggan, is often enclosed in sweeping bands. The intricate polychromy of the malanggan is absent, however; white is the main colour, with touches of red and black. Small uli were perched on conical constructions; large ones were housed in similarly conical huts. The ceremonies associated with the uli were elaborate, but their significance—apart from a relationship to fertility and warfare—is obscure. Wood figures in the same powerful style were topped with skulls over which clay had been modeled; these were used in rainmaking as well as in mortuary ceremonies. Among some central groups, mortuary ceremonies also featured a large bark and cane disk with a central aperture framed by petallike projections. The disk was painted red and yellow and was kept in a hut with posts carved with the same emblem, apparently of the sun. Skulls were displayed in the disk’s central aperture. The design was echoed in the kapkaps, which were worked with exquisite delicacy in central New Ireland.

The southeastern style area of New Ireland includes small nearby islands and the northern Gazelle Peninsula of New Britain. In the north of this area, figure sculpture takes the form of small chalk figures of males and females, with rounded faces, round eyes, straight noses, and wide, toothy mouths. The hands are joined in front of the torso. The white chalk is accentuated with touches of black and red—a colour scheme prevalent throughout southeastern New Ireland. Sometimes said to have been made for mortuary ceremonies, the chalk figures more probably were used by secret societies such as those on the Gazelle Peninsula.

Several types of masks were made in the area. The masks of the Tanga Islands were ephemeral constructions of bark and fibre over bamboo frames. They were semiconical in shape, with long backswept ears, thin upturned noses, and extended chins or beards. On the neighbouring mainland, masks were made of the same materials but were more naturalistic. Masks from the southwest were made of wood and had faces similar to those of the chalk figures. The end walls of houses were frequently screened with planks that were incised or painted with small and sparse units of design, often showing stylized animals and fish. Architectural sculpture, however, was rare except in the Tanga Islands and on the southwestern coast.
