title: Aspects of late quaternary stratigraphy and evolution of some coastal embayments on the east Coromandel Peninsular, New Zealand

authors: Abrahamson, Linda

abstract: The stratigraphy, morphology and sedimentology of the late Quaternary deposits of eastern Coromandel coastal embayments are described, and depicted on a series of ~1:12 500 scale geological and morphological maps. Five stratigraphic units are recognised on the basis of morphology, chronology and depositional environment. The sequence consists of sediments deposited as barrier shorelines, and in the lee of barriers in estuarine and fluvial settings. Prograded, stationary and, rarely, receded barriers are identified, giving rise to three major coastal embayment categories, namely prograded barrier spit embayments, bay barrier embayments, and strand plain embayments. The various barrier types formed in response to different environmental controls, mainly sediment supply rates, coastal configuration and shelf dimensions.

The barrier sediments are mainly mature quartzofeldspathic-rich medium sands derived from reworking within the nearshore system. The fluvial sediments are typically immature, poorly sorted gravels, sand and muds transported from the hinterland by rivers. Estuarine sediments are commonly organic- or shell-rich medium to fine sand containing in situ plant remains and in situ estuarine shells. Ultimately, the sediments have been derived from stream and coastal cliff erosion of surrounding Whitianga and Coromandel Group Volcanics.

Distinctive tephras (Rotoehu Ash, c. 50 ky BP; Tuhua Tephra Formation, c. 6.2 ky BP; Taupo Pumice Formation, c. 1.8 ky BP; and Loisels Pumice, c. 650 y BP) constitute marker horizons in the deposits and, along with radiocarbon dates, have enabled the age structure of the barriers to be determined. Other relative age methods, including vegetation succession, soil development and weathering products, support the coastal chronosequence established from the interbedded tephras .

A model is synthesised to explain the accumulation of sand within the coastal embayments during the late Quaternary. Sea level changes are inferred to be the major control on sedimentation. Two main depositional phases are recorded by the barrier deposits (Pleistocene and Holocene barriers), and are associated with the last interglacial (c. 125 ky BP) and Holocene (6.5 ky BP to present) sea level stillstands. Since sea level reached its present position 6.5 ky BP, the Holocene barriers have experienced several phases of accretion and erosion due to variations in wave regime and sand supply into the embayments. Depositional environments are inferred for Pleistocene barrier samples from multivariate discriminant function analyses of sample textural data, and enable the estimation of the·last interglacial sea level position and subsequent tectonic movements along the east Coromandel coast from the relative displacement of this level.

title: PATHA's vision for transgender healthcare under the current health reforms

authors: Veale, Jaimie

abstract: Aim: The Aotearoa New Zealand healthcare system does not adequately meet the needs of transgender people. Due to healthcare reforms and increases in funding and awareness of transgender health, the Ministry of Health has met with the Professional Association for Transgender Health Aotearoa (PATHA) to discuss ways to improve the healthcare system. We developed a vision for a transgender healthcare document to enable a process for our members to collaborate and to increase transparency about what advice PATHA has provided to the Ministry. Method: Feedback from PATHA’s committees was incorporated into a draft document, which was then sent to all PATHA members for further feedback and collaboration. Results: PATHA proposes improvements to transgender healthcare that are centred around a new transgender health resourcing hub, which should operate according to a Te Tiriti o Waitangi framework, provide national coordination of a distributed model of care, provide resourcing (including education) for primary care and actively work to increase provision and equity of gender affirming surgeries. In order to be effective, the new resourcing hub would utilise peer health navigators, provide education and professional development, promote healing-focussed care and incorporate transgender community leadership and accountability. Conclusions: These improvements would allow for the best practices from existing regional programmes to be implemented throughout the healthcare system. The proposed changes align with the goals of the healthcare reforms to make healthcare for transgender people more equitable, accessible and cohesive.

title: Report on the bicultural symposium at conference

authors: Masters-Awatere, Bridgette

subjects: Maori

abstract: Kia ora koutou. I decided to submit the current paper as a way to say thank you to the large group of people in attendance at the bicultural stream at the national conference in late August that was held at Waikato University. It was their continued presence and participation that served as a catalyst and motivator for this paper. I'm conscious that while there was a large number of people in the symposium, there were other streams occurring at the same time, so I thought giving an overview of the success of the symposium would be a good way to let people know who the symposium went. However, before talking specifically about the symposium, I'd like to give mention to other events of the day...
