TANK 25, 1979 ARCHAEOLOGICAL SITE SURVEY ON PONUI ISLAND, HAURAKI GULF, NEW ZEALAND by Peter J. Matthews 3 Sadgrove Terrace, Mount Albert, Auckland 3 SUMMARY Thirty four archaeological sites were recorded on Ponui Island in August 1978. These include pits, terraces, middens (10), pa (3) and an oven. Thirty three of these sites have not been previously recorded, bringing to sixty six the number of sites now known on Ponui. The present survey indicates that there is a considerable density of sites on the island. In this respect the island is similar to others in the Hauraki Gulf. INTRODUCTION During the week of Saturday, August 26, to Friday, September 1, 1978, descriptions were made of archaeological sites found on the western arm of Ponui Island, between Oranga Bay and Green Bay, and inland to the highest point (170m A.S.L.) on the island. The survey covered about 397 hectares, a fifth of the islands' total area of 1770 hectares (Fig. 1). Ponui Island is the most eastern of the Inner Gulf islands, and lies between Waiheke Island and the mainland. The coastal settlement of Kawakawa is 5.4km away on the mainland coast while Waiheke I. is a little over 1km to the northwest. From north to south the island is 8km long and at Kauri Point is 3.7km across. The topography is generally hilly, rolling in parts. Most of Ponui Island has been cleared for livestock farming, but there are remnants of kauri (Agathis australis) and broadleaf forest. These remnants are mainly west and south of the trig. Raupo (Typha orientalis) swamp is found in some valleys. The coast provides a rich variety of shore types with sand or shingle beaches, tidal mudflats and rocky shores. PREVIOUS WORK In 1963, Davidson recorded 30 sites (N43/1-30) from coastal areas around the southern end of Ponui. Between 1956 and 1962 a series of small excavations were undertaken on a large midden site (N43/1) at Motunau Bay, southern Ponui (Nicholls 1963, 1964; Fisher 1964). A small excavation was also carried out at Galatea Bay (Fig. 1) on a beach stream midden (N43/33) in April 1965 (Terrell 1966, 1967; Shawcross 1967; Moore & Tiller 1975; Davidson 1978). 23
There are unpublished records of two further sites: N43/34, a pit, midden and possible terrace on a ridge above Galatea Bay, and N43/373, a beach midden site in the first bay north of Galatea Bay. Several artefacts from various parts of the island are in the Chamberlins' possession. Among many stone adzes is one of well finished nephrite. There are also 2 wooden digging sticks from the swamp behind Oranga Bay (Fig. 1). ANNOTATED FIST OF SITES Site record numbers (e.g. N43/629) are those of the New Zealand Archaeological Association Record File. More detailed records are in the NZAA File, held at the Auckland Institute and Museum. Grid references (e.g. 674592) refer to the map NZMS 1, Sheet N43, Ponui, 3rd edition, 1975. Site distribution is shown in Fig. 1.

are often situated in places where the natural topography provides defence. Occasionally, despite the absence of obviously defensive earthworks (e.g. site N43/654), the strength of the natural defences is evidence for a pa (Diamond 1963). There are five pa sites in the area surveyed (Fig. 1). These can be classified according to their topographic position (Golson & Green 1958) as two ridge peak and three coastal headland pa. The two ridge peak pa (N43/654, 657) are quite dissimilar. N43/654 has good natural defences on all sides, but no obviously defensive earthworks. Some may have been obliterated by the farm road encircling the peak. The summit is a flat platform with its area partitioned by a low artificial bank (Fig. 4). N43/657 is a smaller site on a smaller peak (Fig. 6). A low defensive bank is placed above the easiest slope. The summit is reached by a path which follows one turn of a spiral. Pits and terraces dot the unlevel area of the summit. The headland pa (N43/20, 25, 30) all feature a defensive ditch across the landward end of the site. Their internal features differ markedly. N43/20 has flat areas in three separately defendable units. Pits are confined to the most landward unit. N43/25 is not at the extreme end of a headland. The seaward end of the site is cut off from a razor-backed ridge by a natural saddle strengthened with a ditch. N43/30 occupies the large area on the top of Kauri Point. Visible earthwork features are concentrated on a small knoll near the landward end of the site (Fig. 5). Undefended Sites These are unfortified and have pit(s) and/or terrace(s). Because pallisade fortification rarely leaves surface evidence, some sites may be incorrectly placed in this category. It is often impossible to determine whether a feature is a pit or a terrace. Only excavation can allow definite judgements. Twenty-four undefended sites have been recorded for the area surveyed (Fig. 1). The actual number is certainly much greater. Many sites seen in the recent survey were not recorded for lack of time. Undefended sites are often small and inconspicuous. When under bush or not on ridges they are easily missed. Twenty-two of the recorded sites are on ridges. Most are on ridge knolls with flattened summits (e.g. N43/661, Fig. 7). Small pits (e.g. 3 x 1.5m, 2.1 x 1.1m) are placed in the top or side of the knoll, or on the ridge top leading up to it. Terraces, also common with these sites, are usually small, like the pits, with two or three sides cut into the slope. Sites with this pattern are particularly common on the ridges about Apuapu Bay. Above Oranga Bay are three sites each with a regular pair of pits in the top of a knoll (N43/647, 648, 650, Fig. 2). The oven or fire pit site (N43/629) is not in immediate association with any other features. Of the two sites not on ridges one (N43/646) may be a gumdiggers' pit, or a natural ground conformation. 31
Fig. 7. Sketch plan of ridge knoll site N43/66T, with profile. The other site (N43/23) is an isolated pit situated close to a good stream, not far behind a beach. It may be a house pit (Davidson 1963). Most of the undefended sites involve little in the way of earthworks. An exception is N43/651, for which a large area has been levelled in stony ground (Fig. 3). Midden Midden is a general term for any sort of rubbish dump. In coastal areas middens usually contain mostly shell, with bone, hangi stones and charcoal to lesser extent. Exposure is most commonly by sea and stream erosion of the natural flat areas behind beaches. Middens are also often found in pa and undefended sites. Eleven midden sites are recorded (Fig. 1). Five of these are close to beaches (N43/24, 632, 638, 643, 660). Three are in level areas ending abruptly above beaches (N43/642, 652, 659). One is below a ridge, on a slope between sixty and ninety metres above a beach (N43/633). Another is in low ground above the swampy area behind a beach (N43/658). One is well inland near a stream and under forest (N43/662). Midden shell was observed at eight of the twenty-four undefended sites, and three of the five pa sites. DISCUSSION Not all the sites in the area surveyed have been recorded, and the descriptions of recorded sites are only brief. There is a bias in field surveying which favours the discovery of sites where travel is easiest and sites are expected, 32
that is, on cleared areas, ridges and beach fronts. Despite these limitations, the survey does allow the following observations: Pa sites are common and are located on headlands and peaks easily accessible via ridges. The distribution of undefended sites on ridges is extensive, and along some ridges is dense. Evidence of the use of marine resources is widespread. There are many beach middens, and shell is dispersed in many sites away from the shore. Numerous pits and terraces are found in both pa and undefended sites. The pits and terraces vary greatly in shape and size. Another Inner Gulf Island of similar size and site density is Motutapu Island, with almost 400 sites (Davidson pers. comm.). This, in addition to the density of sites in the areas of Ponui that have been surveyed, suggests that there are many more sites to be recorded on the island.
