Over the last decade the concept of community archaeology has become a worldwide phenomenon; a convenient tagline largely describing the involvement of non-archaeologists in the practice of interacting with, uncovering, interpreting, and presenting the past. A plethora of new definitions and methodologies have been postulated, a marked increase in public funds invested in such initiatives is notable, as is the development of more rigorous evaluation strategies. Using Etienne Wenger’s ideas about ‘communities of practice’ (1998), I argue that community archaeology can be conceived as a form of knowledge management. In doing so, this paper reflects on the interactions between a small research team and local community during six months fieldwork on Uneapa, a remote island in the Bismarck Sea, Papua New Guinea. It considers the sets of relations that emerged whilst fi?eld-walking, surveying, and excavating Uneapa’s monumental landscape, and discusses how local ideas and knowledge influenced and altered the project methodologies and research questions being asked. This paper also highlights the challenges faced when reifying such engagements into research outputs.
