“…Its migration southeastwards coincided with clockwise transcurrent movement along a fault parallel to that subduction zone, a conclusion also reached on tectonic grounds by Kear (1993). Cole (1979) also figured the two belts in Northland, without stressing that they persisted southwards to the present. Later (1986) he showed the Taupo Volcanic Zone as comprising an andesitic arc (Tongariro Centre to Whale Island) with an ensialic marginal basin to its immediate northwest.…”

“…Their Northland-Three Kings Rise Arc encompassed the two belts proposed here to c. 3 Ma ago, when it came into line with the Tonga-Kermadec Arc. Cole (1979) showed an older trough off the northeastern coast, which was related to Northland and Coromandel volcanism. Its migration southeastwards coincided with clockwise transcurrent movement along a fault parallel to that subduction zone, a conclusion also reached on tectonic grounds by Kear (1993).…”

“…1), and within the overriding plate a zone of NW-SE compression, imbricate thrusting and en echelon folds, with a pervasive NE structural fabric (the accretionary borderland of Lewis, 1980, or East Coast deformed belt of Sporli, 1980). Far removed from the trench and to the west of the East Coast deformed belt, is a zone of transcurrent shear (the frontal ridge) and further to the west, an extensional rift with active calc-alkaline volcanism (the Taupo Volcanic Zone- Cole, 1979; see Cole and Lewis, 1981, figs 1 to 3;van der Lingen, 1982, fig. 2; Stern, 1985).…”

At Mt Miroroa , indurated Mesozoic basement rocks have been faulted over Late Tertiary alternating marine sandstone, siltstone and pebbly limestone. The fault plane strikes NW-SE and dips at 45°SW. The younger sediments are flat lying to the north, but towards the Miroroa Fault they are steepened on the southern limb of an ESE trending syncline, and in places arc overturned. The 3 km long Miroroa Fault is truncated by the northeast-trending Ruahine and Comet Faults. Considerable deformation is evident above and below the Miroroa Fault, although the shear plane is only 5 cm thick. Topographically bclow but subparallel to the Miroroa Fault, several normal faults have raised horst wedges of basement rocks into the Late Tertiary strata.Conjugate minor fault couples immediately below the decollement indicate maximum principal stress to be low-angle and oriented NE-SW. Strain ellipsoids constructed from deformed fossils beneath the Miroroa Fault confirm this orientation. Conjugate faults within a 10 km radius north of the fault indicate NE-SW shortening directions with a subordinate easterly component.In terms of plate tectonic nomenclature, Mt Miroroa lies within the frontal ridge. Sites elsewhere in the frontal ridge of the North Island also indicate NE shortening. It is suggested that the Miroroa Fault either (1) began as a northwest trending normal fault, that was subsequently overturned to its present-day reverse geometry by continued NE-SW directed compression, or (2) developed as an en echelon or side stepping fault between the adjacent Cornet and Ruahine Faults.

“…Lake Taupo, in the central North Island, is the largest lake in New Zealand (617 km 2 ) and is a caldera formed from multiple eruptions of the Taupo volcano since the early Pleistocene (Grange 1937;Cole 1979). The size of the Lake Taupo Catchment is 2673 km 3 excluding the lake (Schouten et al 1981).…”

Effects of artificially controlling levels of Lake Taupo, North Island, New Zealand, on the Stump Bay wetland

The Stump Bay wetland is part of the South Taupo wetland, situated on the southern coast of Lake Taupo in the central North Island, New Zealand. The water level of Lake Taupo has been artificially controlled since 1941. The present study found that surface and subsurface water levels in the wetland are closely related to each other. These water levels are influenced mainly by rainfall and evapotranspiration (which is seasonal) in areas that are greater than c. 100 m landward from the lake edge, but by the lake level for areas in close proximity to the lake. The wetland is a discharge and/or through-flow area, and the general flow direction is towards the lake. The time lag for a groundwater rise in the eastern part of the wetland after rainfall was found to be 24 h. The artificial regulation of the lake level has led to a 2 cm rise in annual mean lake levels since 1950. However, when means are calculated for each month separately, the artificially controlled lake level is up to 20 cm higher in the summer than the pre-controlled summer levels. Significantly † Corresponding author. M99016Received 25 March 1999; accepted 10 November 1999 higher summer lake levels since 1941 are likely to have caused the observed increase in water levels in the Stump Bay wetland area. Further increases in lake levels are likely to decrease areas of native shrub communities and encourage spreading of the exotic shrub Salix cinerea. Lowering in lake levels may decrease areas of native low-stature vegetation, but the spreading of native shrub communities may be curbed by competing S. cinerea.
