title: Lithofacies, paleoenvironments and elements of sequence architecture, Late Oligocene - earliest Miocene Castle Craig Subgroup (Te Kuiti Group), Waikato-King Country Basin, New Zealand

authors: Kamp, Peter J.J.

abstract: This report presents a comprehensive facies and sequence stratigraphic analysis of the Late Oligocene Castle Craig Subgroup (Orahiri Formation and Otorohanga Limestone) within the Late Eocene – Earliest Miocene Te Kuiti Group in the Waikato-King Country Basin in central-western North Island, New Zealand. Detailed field investigations have identified 12 lithofacies within the Castle Craig Subgroup, which have been grouped into three lithofacies associations named limestone, mixed carbonate-siliciclastic sandstone, and siliciclastic sandstone after the dominant lithologies. In areas south of Aotea Harbour the subgroup comprises a wide variety of limestone types with variable siliciclastic content, dominated by coarse skeletal rudstone/grainstone, with aggregate stratigraphic thicknesses of up to 100 m. These sediments accumulated at shelf depths in a moderate to highenergy tidal seaway. Around Raglan Harbour and in areas to the north, the subgroup comprises predominantly planktic foraminiferal-rich packstone to wackestone and calcareous siltstone/marl that accumulated mainly in slope/upper bathyal settings.

title: Wetland biodiversity in Aotearoa New Zealand: an eDNA perspective on exotic and non-exotic species

authors: Bird, Starsha

abstract: Invasive species threaten biodiversity in Aotearoa New Zealand. In wetlands − significant sites that provide an array of ecosystem and cultural services but represent <10% of their original extent − invasive species can affect hydrological function, nutrient regimes and overall ecological functionality. Environmental DNA (eDNA) has emerged as a valuable biomonitoring technique for cataloguing biodiversity and detecting biological incursions, but little is known about how biodiversity varies in wetlands over fine and broad spatial scales. Here, we examined the publicly available eDNA database of Wilderlab New Zealand, retrieving data from 26 sites across the country to characterise taxonomic diversity patterns, including the extent of exotic and non-exotic (native and endemic) species. We found significant spatial variation in biodiversity–even among neighbouring sites–and a pattern whereby all sites had ≥50% exotic species in their total species tally. Our results provide new information on the current state of wetland biodiversity in Aotearoa New Zealand and highlight the value of eDNA databases for generating new insights from publicly shared data. They also emphasise an urgent need for greater resource allocation to conservation and restoration initiatives in Aotearoa New Zealand that will ensure the persistence of treasured native and endemic wetland species.

title: Angitūtanga o ngā tauira Māori:  Supporting Māori students to succeed in psychology

authors: Martin, Dionne

subjects: Psychology

abstract: Many Māori seek out university degrees to make a meaningful impact on the health of their community. Psychology, is one avenue that attracts Māori to do so. Psychology training has often failed to meet the needs of Māori students, often creating barriers to Māori student success. This thesis will explore barriers and support mechanisms that Māori students experience while attending university in pursuit of psychology degrees. This study will focus on experiences had by those enrolled in The School of Psychology at The Univeristy of Waikato, on the Hamilton campus. Informed by kaupapa Māori guidelines and analysed though the use of pūrākau this thesis highlights some key experiences shared by Māori psychology students. Three key experiences were identified. First, the prominence of Western culture in The School of psychology and the impact that has on Māori sense of belonging and whanaungatanga. Second, support system realities for Māori, identifying key university supports systems and realities associated with ones home environment. Third, the transitional journey to becoming a psychologist and what impact that has on the university journey. With this in mind, some recommendations are made to support Māori student success in psychology. These recommendations advocate for the provision of a more bicultural learning experience, creation of a culturally affirming environment, recruitment and retention of culturally capable staff, appropriate resourcing, funding and training for support services, better support for Māori realities and pathway navigation support.
