Kastom vs the fourth estate: An ethnographic study of journalism in Papua New Guinea

The term kastom broadly refers to the traditional systems of beliefs and values found across the islands of Melanesia, encompassing indigenous knowledge passed informally between generations through oral traditions. While these systems vary between communities, in Papua New Guinea (PNG), the region's largest and most linguistically diverse nation, kastom continues to inform professional life, including the practice of journalism. This article explores the relationship between kastom and news reporting in PNG through a combination of video ethnography and semi-structured interviews. Drawing on Melanesian research methodology, the study shows how journalists themselves understand their profession and examines whether existing Western-style journalism training adequately prepares journalists for practice in PNG. The discussion highlights the difficulties and negotiations journalists encounter as they balance professional expectations with social and cultural obligations. The paper outlines core principles of kastom , as expressed through the wantok system, a network of kinship and reciprocal obligation, and illustrates how these norms inform the everyday experiences of journalists. While the study is interpretative rather than normative, the authors propose the concept of ‘polite watchdog’ as a culturally grounded framework that describes how journalists critically engage with powerful sources while maintaining respect for kastom . This model suggests that democratic accountability can be pursued in ways consistent with local epistemologies, offering insights for other postcolonial contexts where Western journalism frameworks intersect with indigenous practices, such as in Fiji, Vanuatu or parts of the Caribbean.
