title: Untying of hands: Working migrants as social agents

authors: Medel, Coni

subjects: working migrant

abstract: This research elicited in-depth settlement experiences from long-term working migrants who migrated to Aotearoa New Zealand, interpreted through an ecological perspective on immigration. The purpose of this study was to provide a contextualised understanding of working migrants’ experiences as social agents. Immigration policies in New Zealand are primarily formulated to extract the economic benefits of migrant labour and to satisfy workforce shortages in certain industries (Terruhn & Cassim, 2023). At the same time, mainstream psychological literature usually focuses on the individual process of ‘acculturation’, describing how migrants adapt and cope in the new place of living (Berry, 2001; Ward, 2001). The community psychology approach in this research focused on addressing the societal conditions surrounding immigrants' difficulties in settling (Birman & Bray, 2017). This research explored how migrants' settlement experiences are shaped by these broader societal dimensions, examining both the resources that helped migrants to become settled and the barriers that made participation difficult.
This research took a case-based study approach. Five working migrants were interviewed about their experiences of the labour market and navigating the immigration system in their real-life contexts. In this study I explored the precarity of migrant workers, regulatory constraints on the labour market, cases of work exploitation but also constructive employment relationship experiences. This research showed that the individual stories and trajectories of migrant workers cannot be comprehended without considering their context. The findings reflected the heterogeneity and diversity of experiences for working migrants. Not all of their experiences were negative, although there were common threads linked with their precarious migrant status. Working migrants in this study experienced a loss of power, autonomy and social status as migrants, and at some point, in their migratory journey, they all sought to move out of their temporariness and precarity, so they could build their lives with more agency.
Working migrants in this study experienced a precarious migrant status due to the regulatory immigration policies that they were subjected to. The main factors of this precarious migrant status arose from their restricted movement in the labour market and a long-lasting uncertain temporal status. Participants affected by their precarious migrant status pursued more autonomy to be able to learn new skills or enhance their existing skills, which opened new opportunities for them in the labour market and also offered broader contributions to the community. This sense of agency also contributed to their personal growth. Working migrants’ experiences extended beyond their workplaces and encompassed broader social spaces. These experiences included participation in the health and housing system, together with achieving a greater work/life balance. Supportive employment relationships, stable and prosperous working conditions and social support led working migrants to develop a sense of home and a sense of meaning in their migration journeys. Permanent settlement was not a primary settlement objective for four working migrants in this study. However, all working migrants shared a need to gain more agency and autonomy. The findings of this study
tentatively suggest that granting working migrants more/full participation may have benefits that outweigh the costs that immigration policies intend to prevent. Through this thesis and by acknowledging the stories of my participants I showed that with the appropriate support, migrants can contribute fully to the receiving community and at the same time improve their well-being significantly.

title: Timing of initiation of reverse displacement on the Taranaki Fault, northern Taranaki Basin: Constraints from the on land record (Oligocene Te Kuiti Group)

authors: Tripathi, Anand Ratnakar Prasad

subjects: Sequence Stratigraphy

abstract: Structures associated with the wedge of basement overthrust into Taranaki Basin along the Taranaki Fault, are regarded as hydrocarbon plays and have been tested by drilling through the tip of the overthrust. The timing of initiation of reverse displace ment on Taranaki Fault is difficult to interpret from available seismic reflection data across it because the evidence has been masked by later movements. The record from the basin, as summarised in King & Thrasher (1996), suggests that the fault evolved from normal to reverse character during the mid-Oligocene. This was inferred from formation of a foredeep parallel to, and west of, Taranaki Fault and a marked increase in its paleo-water depth, as indicated by foraminiferal assemblages of Late Oligocene age.  
A comprehensive re-assessment of the lithostratigraphy and sequence stratigraphy of the Late Eocene-Oligocene Te Kuiti Group exposed on land east of Taranaki Fault in central-western North Island, between Port Waikato and Awakino, provides new constraints on the early history of Taranaki Fault displacement. New age control has been achieved by a review of existing foraminiferal biostratigraphy combined with determination of Sr isotope ages from macrofossil samples. Six unconformity-bound sequences have been identified and mapped within the Te Kuiti Group. A major subaerial unconformity between sequences TK3 and TK4 combined with a basinward shift in the position of onlap for sequence TK4 indicate a dramatic change in stratigraphic development and basin dynamics during the mid-upper Whaingaroan at c. 29 Ma, corresponding to the change from mild extension (sag basin) to shortening across the Taranaki Fault Zone. We consider sequences TK4 – TK6 to each represent tectonic cycles of subsidence and basin inversion and we attribute the origin of these cycles to periodic locking of the Taranaki Fault décollement in underlying Murihiku basement, the accumulating strain causing uplift in the basin east of the fault zone, followed by free displacement, relaxation in the upper crust and subsidence. A 1st order model is presented of the Late Oligocene to earliest Miocene vertical and horizontal displacement of basement on the Taranaki Fault Zone for a west –east transect through Awakino. It implies that the mid- to Late Oligocene displace¬ment on the fault zone in the vicinity of Awakino was episodic, and that the thrust belt was narrow (c. 15 km). North of Kawhia Harbour there will have been a different displacement history with most of the total displacement occurring during the devel opment of the c. 29 Ma unconformity at the base of Sequence TK4, whereas to the south between Awakino and Kawhia Harbour the majority of the total displacement occurred during the Otaian and at the end of it. The model also shows that the start of reverse/thrust displacement on Taranaki Fault must have involved the development of a completely new fault trace(s), rather than involving a change of sense of movement on the pre-existing normal fault. The Manganui Fault is part of the Taranaki Fault Zone and probably became active at c. 27 Ma during development of the unconformity between sequences TK4 & TK5. The model presented here has been validated against the subsurface Oligocene stratigraphy in Taranaki Basin.

title: Dendroarchaeology in New Zealand: extending the range of archaeologically useful species beyond kauri (Agathis australis)

authors: Boswijk, Gretel

abstract: Accurately establishing calendar dates for Māori wooden objects would place them in a secure temporal context and enable aspects of manufacturing and use to be explored within and between sites, and across time. Dendrochronology has the potential to produce accurate and precise calendar dates for wooden artefacts but in New Zealand application of this technique to Māori cultural material is limited as there is almost no overlap between wood species found in archaeological contexts and tree-species with proven suitability for tree-ring dating. Here we identify five archaeologically-useful species – kahikatea (Dacrycarpus dacrydioides), matai (Prumnopitys taxifolia), miro (Prumnopitys ferruginea), rimu (Dacrydium cupressinum) and totara (Podocarpus totara) – and assess their potential for dendrochronology. Of these, matai, miro and totara are identified as species that should be the subject of further comprehensive dendrochronological investigation.
