TL;DR: In this paper, seismic reflection data have been used to investigate the structure and evolution of the continental back-arc basin forming the volcanic region of central North Island, New Zealand, and a caldera structure is tentatively identified under the western part of the younger rift basin (offshore TVZ) from seismic and other data.

TL;DR: In this article, the intermediate depth seismicity appears to arise from a fragment of the Indian plate, subducted at Puysegur Trench and subsequently moved northwards by the transcurrent motion between the two plates.

TL;DR: The Wairau Fault is a series of northeast-trending fractures, one of which runs west of Kapiti Island towards the mouth of the Rangitikei River.

TL;DR: In this article, a series of 114 shots were fired in Lake Pukaki and recorded in three modes: on a 120 channel, 6 km long, seismic reflection array rolled along a 27 km profile on the eastern margin of LakePukaki; on a Reftek seismograph array consisting of 40 units spread over a 52 km long line, partially coincident with the reflection profile; and wide angle reflections from the lower crust recorded on permanent stations of the New Zealand Seismograph Network that were located between 80 and 120 km from the shots.

TL;DR: In this article, wide-angle reflection/refraction seismic data along a two-dimensional profile reveal a low-velocity lower crust and mantle beneath the Dunedin volcanic center, which may represent a hot, fluid-rich region of the crust.
