In the North of Kanaky New Caledonia's Grande Terre (Oceania), large ceremonies which periodically elaborate relations which are at once social and cosmic, and which then will prevail in everyday life. These institutions of the Kanak world can be attended by hundreds of people. They are mainly cycle of life ceremonies and ceremonies dealing with local entities. I outline an anthropological model which highlights the dynamics of these ceremonies and puts forward the concept of ceremonial set, which is aimed at understanding some of the ceremonial principles. One of these is, within a dyadic framework, the use of specific forms of transfers and circulations of specific objects, always synchronised with ceremonial speeches, in order to plait and tie relations. This suggests several contrasts between this approach and some theories of rituals or exchanges. In this text, this model is mainly put forward to reflect upon the role of ceremonial objects, through their circulations, their meanings, their articulations to verbal discourse and towards the relations which, together, they elaborate during the course of these ceremonies.
