International knowledge markets rely heavily on a ready supply of highly mobile doctoral students, many of whom are from the global South, to bring in revenue. The supervision of these PhD students, however, can reproduce neo-colonial knowledge relations, often in subtle ways. In settler nations, international PhD students may find that they are assigned subaltern status in their university departments and this can have a significant impact on their learning. This paper explores the experiences of a group of international PhD students in a social science faculty in a New Zealand university during the first two years of their doctoral studies. It examines how they responded to the displacement of their cultural values and priorities, the way they navigated intercultural engagements with supervisors, and their ensuing relationships with indigenous and ethnic allies in the faculty. Despite considerable pressure to conform to the dominant modes of academic knowledge production that characterise universities in settler nations, it is concluded that international students find ways of speaking out, often in highly coded forms, that complicate their subaltern academic status.
