This paper discusses the archaeological evidence previously available from the region of Naïa, Ongwé and Saint-Vincent Bays on the south-western coast of New Caledonia and presents new data from the same region. Rich pottery deposits attest 3,000 years of continuous occupation characterised by remains from the Koné, Naïa 2 traditions. The earliest occupation during the Koné period was organised in small hamlets, which may have been grouped in larger settlements. These early sites seem to have disturbed by eustatic and coastal adjustments. The Naïa period saw the development of large communities of potters whose main product was large pots with handles, a type of vessel not known elsewhere in early Pacific communities. (Résumé d'auteur)
