“…These ages are supported by the presence of Kawakawa/Oruanui tephra within aggradation deposits and by OSL ages on loess derived from LGCP riverbeds (as discussed in the following section; also Litchfield and Rieser (2005) and Litchfield and Berryman (2005)). A regional change from aggradation to incision occurred at Termination I. Rerewhakaaitu Tephra (17 625 AE 425 cal.…”

“…excluding glacial outwash sequences). A switch from aggradational to degradational or vice versa occurs in response to a change in one or more external controls, including climate, total basin relief, base level, tectonics and human activity (Litchfield and Berryman, 2005, and references therein). The impact of climate change on rivers in New Zealand has long been recognised (Vella, 1963;Milne, 1973b;Palmer et al, 1988;Pillans, 1994), and recently the role of other controls such as sea level and tectonism has started to be addressed (Browne and Naish, 2003;Litchfield and Berryman, 2005).…”

“…G1-G27, F1-F5, and L1-L6 represent key glacial (G), fluvial (F), and loess (L) references, and are ordered as set out by Barrell et al (2005). This figure is available in colour online at www.interscience.wiley.com/journal/jqs Berryman, 2005;Litchfield and Rieser, 2005). OSL dating of loess provides minimum ages for some fluvial terrace deposits (Formento-Trigilio et al, 2003).…”

“…In the North Island, there is a clear climate control on the terrace formation (Litchfield & Berryman 2005), which provides isochronous markers across the whole island for the different aggradation phases. For the purpose of this study, we have used generalised ages of these markers, and thus we have assigned the ages shown on Table 2 to the surfaces found in this area.…”

Late Quaternary structure and kinematics at the southern termination of the Taupo Rift are investigated by means of active fault mapping and estimates of fault displacement and extension rates. Active faults in the southern Taupo Rift are normal in sense and include three major structures: the NNE-trending Mt Ruapehu Graben; the E-W to ESE-WNWtrending Ohakune-Raetihi fault set; and the NE-trending Karioi fault set. Displacements of young geomorphic features, fault plane exposures in roadcuts, and trenches across faults show that all faults are active contemporaneously. The Mt Ruapehu Graben is the southern extension of the modern (i.e., <26 ka) Taupo Rift (or Taupo Fault Belt, TFB), and has developed as a result of backarc extension related to the Hikurangi subduction margin. Geologic extension rate for the Mt Ruapehu Graben is estimated here at 2.3 ± 1.2 mm/yr. The other two structures strike almost perpendicular to the Taupo Rift terminating the Mt Ruapehu Graben to the south. The co-existence of three normal fault sets in mutual crosscutting relations and with no significant strike-slip on any of them may be related to local reorientation of the minimum principal stress axis (σ 3 ) or to a stress tensor where |σ 3 | |σ 2 |. Complicated strains at the southern termination of the Taupo Rift are related to block rotations in the Hikurangi subduction margin.

“…The terraces comprise Heretaunga alluvium, fossiliferous marine sands and greywacke interlaced with fluviatile sand and silts [42]. Preservation of terrace flights reflects local and regional uplift and oscillating climatic conditions between glacial (aggradational) and interglacial (degradational) periods [42].…”

Systematic grain size measurements were recorded for all geomorphic units in 41 cross sections spaced 400-800 m apart along the lower course of the Ngaruroro River. Although the surveyed bed slope has a uniform grade through this reach, valley width imposed by terrace margins increased markedly, with a notable increase 6 km down-reach. Mean grain size and D 95 diminution coefficients of 0.052 and 0.073 were determined for the 19 km study reach. Marked differences in downstream fining trends were evident for the zones upstream and downstream of 6 km, with significant fining upstream of 6 km and more subdued fining downstream of 6 km (D 95 diminution coefficients of 0.109 and 0.017 respectively). The increase in active channel area associated with the increase in valley width is considered to mark a process control shift from competence-limited to capacity-limited conditions. Selective entrainment rather than abrasion is inferred to be the primary mechanism for downstream fining. Lateral confinement also affects patterns of geomorphic units. The competence-limited environment (upstream 6 km) comprises stabilised bars, stabilised gravel sheets and gravel sheets while the capacity-limited environment (downstream of 6 km) is characterised by significant lateral variability of gravel sheets, high flow chutes, ridges, ramps, platforms, stabilised bars and stabilised gravel sheets. Findings from this study highlight the importance of lateral confinement as a control on river processes and forms.
