In Aotearoa/New Zealand, during the period known as the M aori cultural renaissance, developing rhetoric about M aori authenticity has emphasized distinctions between tribal and urban M aori. This has been in part due to the juridification of M aori property by the state and the concomitant retribalization. In recent years, however, there are signs that this essentializing tendency might be lessening as the passing of time has brought M aori successes in many fields. The process of reasserting themselves and renegotiating their relations with non-M aori involves issues of participation and political representation, including at the local government level. This paper looks at these changes and at the debate around M aori representation on Auckland's new Super City Council and the resulting present situation. It shows that concerns about authenticity wax and wane, depending on the larger political context. [M aori, New Zealand, authenticity, political representation, local government]
