title: Location of Te Wahitapu Stream and other possible streams in 1877

authors: de Lange, Willem P.

abstract: Review of evidence to establish, with as much confidence as possible, the path of the Te Wahitapu Stream at Matapouri in 1877. The review also examines if other streams may have been present on or in the vicinity of Te Wahitapu Stream in 1877, and if the 1877 or later tsunami may have latered the course of the boundary stream.

title: Homeless Māori Men: Re-connection, Re-joining, and Re-membering Ways of Being

authors: King, Pita Richard Wiremu

subjects: Māori psychology

abstract: There are a range of interventions and programmes to address the on-going issue of Māori homelessness. This thesis explores a gardening project hosted by a Ngāti Whātua marae (communal complex used for everyday Māori life) in Auckland for homeless Māori men. The garden project facilitates a sense of belonging, dignity, purpose, meaning and connectedness with other Māori people. It provides insights into how culturally-patterned relationships are centrally important to resolving the overrepresentation of indigenous peoples’ in homelessness populations. I employ the use of semi-structured interviews, reflective journaling, and photography as techniques to record and document the daily interactions in the marae gardens. Participants came from three distinct groups, which include: homeless Māori men, the Auckland City Mission, and Ngāti Whātua o Orakei. A total of eight participants were formally interviewed, along with another six who engaged in casual conversations, in this research, with ages ranged from 30 to 70 years of age. Key findings from this research relate to the construction and preservation of Māori identity while in a state of homelessness, the functioning of marae as spaces of care that foster the wellbeing of Māori, and the role of food in the reproduction of Māori cultural values in everyday life. The broader significance of my work is to use indigenous concepts to build an understanding of the activities, needs and relationships of homeless Māori men that they can recognise themselves from.

title: Alum dosing effects on fish and aquatic invertebrates: Utuhina Stream 2024

authors: Ling, Nicholas

abstract: To reduce external phosphorus loading to Lake Rotorua, the Bay of Plenty Regional Council has been granted resource consent to dose the Utuhina Stream with alum (aluminium sulphate). Aluminium binds phosphorus, preventing its uptake by phytoplankton and thereby inhibiting growth. Aluminium forms monomeric species outside of circum-neutral pH (pH 68), and these species can disrupt osmoregulation and respiration of aquatic organisms. The alum dose rate to the Utuhina Stream is dependent on discharge, with a maximum application rate of 1 mg Al L-1. This report presents the results of an on-going assessment of the fish and aquatic macroinvertebrate communities of the Utuhina Stream for 2024.  Macroinvertebrates, fish and kōura (freshwater crayfish; Paranephrops planifrons) were sampled from one control (site 1) and two treatment (sites 2 & 3) reaches of the Utuhina Stream. Common bully (Gobiomorphus cotidianus) were the dominant species of the fish community, with juvenile trout and kōaro (Galaxias brevipinnis) also captured. Kōura were present at all sites but variable in abundance. There was a notable decline in the semiquantitative macroinvertebrate community (for soft-bottomed streams; MCI-sb) score at Sites 1 and 3 in 2024 compared to long-term site averages, with Site 1 declining into the ‘poor’ category. Interannual variation in MCI-sb scores is typical for these reaches of the Utuhina Stream and have been attributed to flood-related disturbances to stream bank morphology and in-stream vegetative cover (Ling 2021). Tissue aluminium concentrations were determined from common bully (flesh, gill, liver) and kōura (flesh, gill, hepatopancreas) by inductively coupled plasma mass spectrometry (ICP-MS). There was some evidence of aluminium bioaccumulation in the liver tissues of common bully at Site 2, but overall concentrations were similar to long-term averages and there were no notable differences for the same tissues between sites. Kōura tissue aluminium concentrations for 2024 were similar to long-term averages across all tissues and sites. A small number of individuals had elevated gill concentrations at Site 3 compared to long-term average concentrations, but this is unlikely to result in harmful physiological impacts. The data presented in this report further supports the conclusion by Tempero and Ling (2024) that alum dosing does not appear to have a notable effect on the fish and kōura community and that site and interannual differences appear to be due to hydrological and habitat variability.
