For hap? of the lands that border its 425-kilometre length, the Waikato River is an ancestor, a taonga and a source of mauri, lying at the heart of identity and chiefly power. It is also subject to governing oversight by the Crown and intersected by numerous power stations managed by state-owned energy companies: a situation rife with complexity and subject to shifting and subtle power dynamics. In this book Marama Muru-Lanning explains how M?ori of the region, the Crown and Mighty River Power have talked about the ownership, guardianship and stakeholders of the river. By examining the debates over water in one New Zealand river, over a single recent period, Muru-Lanning provides a powerful lens through which to view modern iwi politics, debates over water ownership, and contests for power between M?ori and the state.
