title: Utuhina Stream 2006-2020: In-stream alum dosing effects on fish and aquatic invertebrates

authors: Ling, Nicholas

abstract: This report presents the results of an on-going assessment of the fish and aquatic macroinvertebrate communities of the Utuhina Stream, Lake Rotorua, from 2006 to 2020, and an assessment of the bioavailability of aluminium in fish and kōura to satisfy Bay of Plenty Regional Council’s annual resource consent conditions 9.6, 9.8 and 9.7, respectively, for consent 65321 for the discharge of alum to the Utuhina Stream. Macroinvertebrates, fish and kōura (freshwater crayfish) were sampled from one control and two treatment reaches of the Utuhina Stream annually. Common bully (Gobiomorphus cotidianus) is the dominant species in the fish community of the Utuhina Stream. Kōura (Paranephrops planifrons) and juvenile trout were always present at all sites but variable in abundance. Differences in species abundance from year to year are most likely due to flood-related disturbances to stream bank morphology and in-stream vegetative cover or physical displacement of fish. No obvious effects of alum dosing on stream fish or macroinvertebrate communities were observed between the upstream control site and sites downstream of the alum discharge. Several other fish species were occasionally captured during sampling and the regular occurrence of juvenile koaro from 2016 to 2019 is possible evidence of this taonga species becoming established in the Utuhina. Analysis of stream macroinvertebrates also showed no consistent differences between the upstream control site and the sites downstream of the alum dosing. Overall, all sites were characterised as fair to good quality for a soft-bottomed stream. Some evidence of aluminium bioaccumulation was seen in some tissues of common bully (gills and liver) in some years, resulting from continuous alum dosing of the Utuhina Stream, but there was no evidence of bioaccumulation of aluminium in the tissues of kōura. Alum exposure in these species does not appear to affect their health or abundance in the stream.   iii Overall, continuous alum discharge does not appear to negatively impact the ecology of the lower Utuhina and improvements in the ecological condition of the Utuhina Stream will be achieved by ongoing riparian restoration and mitigation of the impacts of flood flows.

title: Decolonisation through reconciliation: The role of Pākehā identity

authors: Amundsen, Diana Leigh

subjects: Pākehā

abstract: Research indicates that claiming a contemporary identity as Pākehā is being redefined by those individuals who engage closely with Te Ao Māori. This reopens the discussion of the implications for Pākehā researchers who engage across Māori research spaces. This article reports a reflective study I conducted using the transtheoretical model and its six stages of change (J. O. Prochaska & DiClemente, 1982) to understand my Pākehā cultural identity. I discuss my rationale for engaging in research with Māori, and then outline the approaches that I, as a non Indigenous researcher, adopted to appropriately engage in Indigenous research. I discuss responsibilities for Pākehā to take deliberate and conscious steps to decolonise through reconciliation and dismantle disturbing and prevailing prejudiced attitudes. Decolonisation through reconciliation takes various forms, but necessarily involves a process of actions and changes. Our challenge as Pākehā educators is to participate in this change process towards decolonisation through reconciliation.

title: Mental health at Tokanui in the early years

authors: Campion, Michelle Edith

abstract: Tokanui was the first hospital to be built entirely to the villa design, and as such, its physically separate wards presented considerable opportunity for the classification and treatment of patients. Piecing together information contained in the remaining records, this chapter describes the formative years at Tokanui, during which not only a hospital, but also a community was established. The narrative which follows tells of buildings erected, land broken, cultivated and beautified, of hard physical labour and trying conditions. Above all, it is a narrative of the people who worked and lived, however fleetingly, at Tokanui and without whom the hospital would not have had a purpose. As the first new hospital to be built after provincial time, Tokanui, in many respects, led the way in developments made in the accommodation and treatment of the psychiatrically ill and those with intellectual disability.
