Neogene paleomagnetism and geodynamics of the Hikurangi margin, East Coast, New Zealand
… Extensive paleomagnetic sampling along the Hikurangi margin, on the East Coast of the North Island, has provided new insights into the patterns, rates and timings of tectonic rotation, and also an improved understanding of the magnetic signature of New Zealand Cenozoic mudstones. Rigorous …

Tectonic evolution of Pegasus Basin and the Hikurangi Trench, offshore New Zealand, The
… strike-slip zone into the actively subducting Hikurangi Trench requires a significant translation of plate motion from margin parallel to margin normal within the Pegasus Basin. The purpose of this research was to understand the distribution of strain along this complex transition, and to …

Analysis of the central Hawke's Bay sector of the Late Neogene forearc basin, Hikurangi margin, New Zealand
… dextral rotation of eastern North Island and the Hikurangi margin. Forty-one lithofacies within the Late Miocene-Early Pleistocene sedimentary succession have been identified and grouped into six lithofacies assemblages. Each assemblage generally corresponds to a broad depositional environment. …

Diverse Economies and Economic Possibilities for Kāinga Housing in Aotearoa New Zealand
… an in-depth, ethnographic case study with Hikurangi Enterprises, a community-owned social enterprise in Te Tairāwhiti of Aotearoa, and their wider network. Drawing on housing political economy (Aalbers and Christophers, 2014), diverse economies (Gibson-Graham, 2006, 2008, Gibson-Graham and …

Igneous life cycles: geochemistry of magma from mantle to surface and back again
… timescales. Slow-slip megathrust events in the Hikurangi forearc region, New Zealand, may be related to seamount subduction. We examine differences in the clast origins, depositional settings, and diagenetic histories of volcaniclastic units to highlight the heterogeneity of volcanic systems on …

Estimating the Adaptation Deficit - An empirical analysis of the constraints on climate change adaptation in agriculture
… case study of adaptive behaviours in the Hikurangi catchment, New Zealand. Data are collected using a mixed methodology comprising an extensive survey of rural decision making, to which this study contributes, and a suite of semi-structured interviews. The interviews give an understanding …

Nature and Potential Origins of the Low-Rate Tectonics of the Hauraki Rift and North-Western New Zealand: A Geophysical Investigation
… 40 km east of Auckland City and oblique to the Hikurangi subduction margin. A three-year 40+ station campaign GNSS geodetic survey was done incorporating previously unused historic data to constrain the crustal motion throughout the north-western North Island and the Hauraki Rift. A screw …

Deciphering the 4-D geological framework of the Taupo-Reporoa Basin: Implications for hydrothermal fluid flow and volcanism
… rates are interpreted as resulting from Hikurangi Plateau subduction processes.

The timescales of andesite generation at Mount Ruapehu, New Zealand
… Pacifc Plate beneath the Indian Plate along the Hikurangi Trough. Major element trends are dominated by shallow level crystallisation and assimilation processes. Modelling of crystallisation trends suggests that the magmas were hydrous and may have elevated fO<sub>2</sub>. Trace element patterns …
