Scholars frequently identify how path dependency serves to constrain the process of climate adaptation and is a key feature of maladaptation. Most studies, however, centre on theoretical, rather than empirical-based discussions of what path dependency is, how it occurs, and what factors assist in breaking path dependency. This paper provides a case study for the creation, maintenance, and attempts to break path dependency within the management of rivers in the Rangitaiki Plains of Aotearoa New Zealand from the 1890s until 2017. We deploy a historical institutionalist theorising on path dependency and institutional arrangements, while also incorporating ideas from indigenous and postcolonial scholarship, which extends current understandings of the factors that contribute towards path dependency at a local level. Through archival research, we demonstrate how successive generations of government policies and actions directed with a specific goal and underpinned by the hegemonic social values created a profoundly path dependent system of managing rivers and flood events. Increased flood vulnerability is one of the direct consequences of the plethora of freshwater engineering interventions which were (and are still) undertaken on the Rangitaiki Plains over the last century. The foundation of this path dependency, we argue, resides with the processes of indigenous dispossession and the marginalisation of Maori values from environmental governance and policy. Efforts to break path dependency, therefore, involve the formal recognition of Maori governance, values, and knowledge within policies, and the translation of Maori values into tangible actions that seek to destabilise Western command-and control approaches to flood risk management.
