“…With the inception of subduction during the late Oligocene, two parallel and co-eval volcanic arcs developed above the southwesterly dipping subduction zone (Brothers 1974;Ballance 1974Ballance , 1976Ballance , 1988Kear 1994). Petrological and geochemical evidence indicates calc-alkaline affinities (Wright & Black 1981;Smith et al 1989).…”

“…The southwest-dipping trench-arc system was initially established in Northland. However, the history of its progression to the present position is still being debated (Kamp 1984;Brothers 1986;Ballance 1988;Kear 1994). Synchronous with this development was the formation of the Alpine Fault as a continuous transform through the New Zealand block, intersecting obliquely the earlier late Eocene to mid Oligocene rift system of western South Island (Kamp 1986b).…”

Apatite fission track (AFT) and vitrinite reflectance (VR) data for early Miocene outcrops from the Waitemata Basin reveal that the basin sequence was subjected to shallow burial before denudation. AFT results suggest that the total sediment thickness within the basin was 1 km and maximum paleotemperatures during burial never exceeded c. 60°C. Statistical analyses of the detrital AFT ages distinguish four dominant sources of sediment supply: contemporaneous volcanism; metagreywacke rocks of the Waipapa Group; the Northland Allochthon; and an unidentified source south of the basin.The apatite and zircon fission track results from the Waipapa Group rocks (Gondwana Terrane) adjacent to the basin suggest two discrete phases of accelerated cooling: the first during the early Cretaceous (c. 117 Ma) and the second during the mid Cretaceous (c. 84 Ma). These events probably reflect key stages in the tectonic development of the New Zealand microcontinent during the Cretaceous period, the earlier event being related to the climax of compressional deformation (Rangitata Orogeny) and the latter to extensional tectonism associated with the opening of the Tasman Sea. Waipapa Group rocks now exposed at the surface cooled from maximum paleotemperatures of c. 250°C at an estimated rate of c. 180-36°C/m.y., involving substantial denudation.

“…Volcanism was mostly andesitic, but included some acidic volcanics (dacite) in the eastern Marshall Belt, and some basic volcanics (basalt) in the western Searle Belt (Kear 1994). The latter included offshore volcanoes which provided volcanic material to the coastal area and to the Waitemata "inter-arc flysch basin" between the belts (Ballance 1974(Ballance , 1976bHatherton etal.…”

“…Six time intervals were involved-three longer ones, each with a relatively consistent tectonic regime, separated by three shorter, more active, "tectonic events" (Kear 1994): the Waitemata (c. 26-25 Ma), the , and the Kaimai (c. 5-2.5 Ma). During each event, a new and different tectonic regime (and consequent pattern of volcanism) was imposed.…”

Kiwitahi Tectonic Event (15-14 Ma) terminatedNorthland volcanism and triggered Coromandel and Kiwitahi volcanism, which migrated southwards in the same two belts. Migration coincided with 200-300 km of transcurrent movement along a now-abandoned Alpine Fault trace, which also transferred the subduction system, Cretaceous sediments, the East Coast Allochthon, Miocene pumiceous beds, and the East Coast region southward. Before 5 Ma, c. 25° of dextral curvature was imposed on the North Island, and relative tectonic quiescence (with consequent intraplate volcanism) extended southwards through Northland and South Auckland.Kaimai Tectonic Event (5-2.5 Ma) halted volcanic migration and imposed another 40° of curvature. That caused the rotational rifting of the Central Volcanic Region, which initially tore away progressively along the Alpine Fault trace, creating three successive volcanic zones -newly proposed Mangakino (2+ Ma to 950 ka), newly proposed Manawahe (950 to 400-350 ka), and previously named Taupo (400-350 ka to today).
