title: “Whānau Vibes”: Reclamation of self, space and community within group fitness gyms.

authors: Metekingi, Cydney

abstract: Group fitness gyms are becoming more popular in Aotearoa, New Zealand. This thesis is an investigation of the lived experiences of Māori members within a commercialised fitness space called BFT Hamilton East, located in Kirikiriroa, Hamilton. Drawing on Indigenous anthropology and autoethnography, and grounded in Kaupapa Māori theory, this thesis firstly explores how the gym becomes a site in which Māori members seek to reclaim the narrative around their own bodies. I explore the colonial depictions, the politics of the Indigenous body and how Māori-owned clothing brands contribute to this reclamation. I then examine how Māori gym members use the gym space with a sense of purpose, balancing the values of culture and commercialisation. And finally, I investigate the importance of relational well-being and the use of whanaungatanga and manaakitanga to create a sense of belonging among participants in their search for connection. In foregrounding Indigenous ways of knowing, being and moving in a commercial group fitness gym, this thesis aims to contribute to the anthropological conversations that advocate for the inclusion of Indigenous methodologies into Anthropology, centring Indigenous agency and advocating for the decolonisation of fitness spaces.

title: Te Raupatu o Tauranga Moana = The confiscation of Tauranga lands. [Volume 1]

authors: Stokes, Evelyn

subjects: Tauranga lands

abstract: A report providing a historical and geographical overview on the confiscation of Tauranga lands. In two volumes, volume one comprises a narrative of the events described as the raupatu, the confiscation of lands in the Tauranga Moana tribal area under the New Zealand Settlements Act 1863.  Volume two is a collection of documents, edited and annotated which were compiled in support of the report. These documents include personal accounts, tribal history, land purchases, lands returned and crown transactions.

title: Automated retrofit of heat exchanger networks

authors: Lal, Nathan S.

subjects: Heat recovery

abstract: In a large industrial processing plant, a significant amount of process heat is generated using fossil fuels, contributing to New Zealand’s overall greenhouse gas emissions. While New Zealand’s renewable energy sources present potential alternatives to fossil fuels, reducing the process heat demand of industrial processing plants is another critical step for emissions reduction, with multiple long-term economic and environmental benefits. Reducing process heat demand often centres on retrofitting the heat exchanger network to improve heat recovery and lower the hot utility consumption. 
This thesis presents a comprehensive automated retrofit design method for heat exchanger networks, fulfilling several gaps in current knowledge. The novel contributions are presented and discussed in four main chapters: (1) two retrofit tools are developed that enable visualisation of the problem – the Modified Energy Transfer Diagram and the Heat Surplus-Deficit Table, (2) an algorithm called Automated Retrofit Targeting that searches for all possible retrofit modifications of the heat exchanger network that unlocks energy savings, (3) a comprehensive energy retrofit planning tool that uses a multi-stage retrofit analysis to provide strategic long-term and cost-effective retrofit plans, and (4) an heat exchanger network simulation method, incorporating using Monte Carlo Simulation, to quantify the effect of variable process flows and temperatures on flexibility and steady state performance. 
The developed methods are illustrated using a simple four-stream network and then applied to two industrial case studies that are representative of some of the large industrial energy-users in New Zealand: a paper mill at a Kraft pulp and paper mill cluster and a petrochemical complex. In both case studies, numerous potential retrofit designs have been identified. These options are reduced to those that ranked as the most cost-effective, using thermodynamic and economic constraints with Pareto front analysis. By successive application of the retrofit method, long-term retrofit plans have been proposed, enabling strategic sequencing of modifications and minimising process heat demand. For the petrochemical complex, the hot utility consumption could decrease by 9.58 MW (63% of the total possible savings) using four separate stages of retrofits. The total retrofit profit would reach 1.5 million Euros per year with a simple payback of 1.7 years. The paper mill could achieve its process heat demand reduction target using four retrofit stages, achieving a total retrofit profit of 0.78 million NZD per year. These modifications resulted in an inflexibility of 51.3% (probability of the heat exchanger network failing to meet all target temperatures), but this could be reduced to 4.1% using bypass control. 
This thesis provides a novel retrofit method, which uses graphical and numerical tools, in combination with automated analysis, generating and evaluating cost-effective retrofit designs. The retrofit design method has been implemented in Microsoft ExcelTM as a critical and functional output that can be rapidly applied to complex industrial heat exchanger networks.
