    The good fight : power and the indigenous struggle for the Manawatū river : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Resource and Environmental Planning at Massey University, Manawatū, New Zealand
    (Massey University, 2015) Bennett, April Leanne
    Power is the central theme of this research. This thesis examines how power structures iwi contributions to freshwater planning and decision-making. Power has received little attention in literature on Māori and natural resource planning, even though it reproduces and potentially transforms existing inequalities among Māori, other actors and planning institutions. In failing to analyse power, scholars have left a significant gap in the literature. In New Zealand, the deleterious effects of agricultural expansion on water have significant implications for iwi, as water is linked to tribal identity and mana. Both past and current generations have struggled to protect water. Contemporary strategies to restore degraded water bodies and reclaim mana, as control and authority, over water include co-management arrangements. Simultaneously, Government has taken an enthusiastic, uncritical stance to promoting collaboration as an approach to freshwater planning, including iwi as one among multiple actors. In this pro-collaboration climate, however, power has been ignored. So, this research asks: How does power structure iwi contributions to freshwater planning and decision-making? To answer this question, a case study was undertaken of the Manawatū River, a highly degraded water body in the lower North Island of New Zealand. Two main methods were used to collect data: semi-structured interviews with 13 key informants and an analysis of 214 documents, including 180 newspaper articles. To interpret the data, the theoretical framework used Pierre Bourdieu’s concepts of field, capital and habitus. The research found that power structures all contributions to freshwater decisionmaking into a hierarchy, with iwi contributions typically marginalised. The hierarchy is a colonial legacy which continues to be reproduced in multiple ways. So, while collaboration, as advocated by the Crown, has some benefits for iwi, it will not help re-structure this hierarchy to enable iwi to regain control over water. Other strategies, such as Treaty of Waitangi settlements, are liable to be more effective. This finding implies that iwi must assess whether co-management or collaboration strategies will enable them to reshape power imbalance. Gaining power is critical to transform inequality, reclaim authority and restore the mauri of water for future generations.

    Quantification of channel planform change on the lower Rangitikei River, New Zealand, 1949-2007: response to management?
    (2010-09-06T21:16:59Z) Richardson, Jane M.; Fuller, Ian C
    The Rangitikei River, a large gravel‐bed wandering river located in the North Island of New Zealand, has outstanding scenic characteristics, recreational, fisheries and wildlife habitat features. Recently concerns have been raised over the potential negative impact that perceived channel changes in the latter part of the 20th century may be having on the Rangitikei River recreational fishery. This study describes and quantifies the large‐scale morphological changes that have occurred in selected reaches of the lower Rangitikei River between 1949 and 2007. This research utilised historical aerial photography and analysis in ArcGIS® to quantify channel planform change in three reaches, encompassing ~18 km of the lower Rangitikei River. This showed that the lower Rangitikei was transformed from a multi‐channelled planform to a predominantly single‐thread wandering planform, with an associated reduction in morphological complexity and active channel width of up to 74%, between 1949 and 2007. Bank protection measures instigated under the Rangitikei River Scheme have primarily driven these changes. Gravel extraction has also contributed by enhancing channel‐floodplain disconnection and exacerbating sediment deficits. The findings of this study have implications for future management of the Rangitikei. Previous lower Rangitikei River management schemes have taken a reach‐based engineering approach with a focus on bank erosion protection and flood mitigation. This study has confirmed the lower river has responded geomorphologically to these goals of river control. However questions as to the economic and ecological sustainability of this management style may encourage river managers to consider the benefits of promoting a self‐adjusting fluvial system within a catchment‐framed management approach.
