The highest peak is 652 m above sea level and a reef flat extends several hundred meter to the reef that then slopes steeply to deep water surrounds the island. Rarotonga is densely covered with a jungle of ferns, creepers and towering trees. Karekare Swamp in Matabera, located in the northeast of the island is a back swamp. We obtained a 340-cm sediment core at the site of the swamp (21°12' 57.5\"S, 159°44' 23.1\"W) using a hand auger sampler. The core sediments were divided into three layers, i.e. sandy peat from 0 to 90 cm, undegraded peat from 90 to 250 cm，and dark brown peat from 250 to 340 cm in depth. This paper present results of pollen analysis and AMS radiocarbon (14C) dating on the cored sediments. Eight 14C dates obtained from charcoal and plant fragments indicate that cored sediments cover the past 6000 years. Arecaceae pollen grains are dominant in all of the sediments. While Barringtonia pollen decreases rapidly in the upper part. The appearance ratio of Pandanus pollen is high in the lower part, but it decreases rapidly in upper layers. The appearance ratio of herbaceous plants such as Poaceae and Cyperaceae is remarkable in the upper layers. Considering that Barringtonia and Pandanus grow in the hinterland, decrease in Barringtonia and Pandanus and increases in herbaceous plants suggest a disturbance of the hinterland vegetation. The appearance of Chenopodiaceae pollen of upland weeds and cucurbitaceae and Vigna pollen grains of cultivated plants suggests definite traces of humanity upper 130 cm. The appearance ratios of Pandanus pollen and monolate type fern spore show the increase in 157 to 147 cm. The radiocarbon age indicates about 3700 BP. Judging from the increase of Pandanus pollen and monolate type fern spore, this result suggests human activities. Hence human settled in Rarotonga at about 3700 BP, which is considerably older than that of settlement in eastern Polynesian obtained before.
