Threading the basket of knowledge: the role of iwi and hapū management plans for natural hazard research design

Lucy H. Kaiser, Wendy S. A. Saunders & L Taylor
The Ministry of Business, Innovation and Employment (MBIE) Vision Mātauranga policy has created a clear message for researchers in Aotearoa/New Zealand—that research conducted in Aotearoa New Zealand should recognise and support the “unlocking of the innovative potential of Māori for the benefit of all New Zealand” and be designed with a clear engagement pathway. However, there is still confusion amongst many researchers on where to begin when considering the Vision Mātauranga component of their research....

Materials for improved assessment of the petroleum source potential of New Zealand coaly rocks, 2: Jurassic to Early Cretaceous stratigraphy, coal abundance, flora and climate

J. Ian Raine, Angela G. Griffin, Elizabeth M. Kennedy, Chris D. Clowes & Richard Sykes
Jurassic to Early Cretaceous strata of New Zealand were deposited at high latitude on the southern margin of Gondwana in several tectonic situations, now recognised as distinct tectonostratigraphic terranes within the Eastern Province of Zealandia. To develop a chronostratigraphic framework of coaly petroleum source rock potential in relation to vegetation and climate, we review the stratigraphy of non-marine strata, estimate relative abundance of coaly lithologies in available exploration wells and outcrop sections and discuss macrofloral...

Towards the calibration of tsunami models in the Auckland region using paleotsunami deposits

Kate J. Clark, Bruce Hayward & Regine Morgenstern
The Auckland region does not have a historic record of any significant tsunamis, but it is exposed to a number of local, regional and distant tsunami sources. Of these potential sources, the largest tsunamis are expected to be generated by large earthquakes on the Kermadec Trench. Tsunami models of large Kermadec Trench earthquakes (M 8.5–9.4) suggest parts of the eastern coastline of the Auckland Region could be exposed to tsunamis with wave amplitudes of up...

Lineage identification affects estimates of evolutionary mode in marine snails

Felix Vaux, Michael R Gemmell, Simon F K Hills, Bruce A Marshall, Alan G Beu, James S Crampton, Steve A Trewick & Mary Morgan-Richards
In order to study evolutionary pattern and process we need to be able to accurately identify species and the evolutionary lineages from which they are derived. Determining the concordance between genetic and morphological variation of living populations, and then directly comparing extant and fossil morphological data, provides a robust approach for improving our identification of lineages through time. We investigate genetic and shell morphological variation in extant species of Penion marine snails from New Zealand,...

Spend to save: investigating the property acquisition process for risk reduction in Aotearoa New Zealand

Wendy S. A. Saunders & G. Smith
Limiting development in known high-hazard areas is among one of the most effective tools available to local governments to reduce future hazard risk and increase resilience, and yet, the widespread practice of acquiring hazard-prone properties and converting the land to open space in New Zealand remains highly varied. This report outlines Aotearoa New Zealand examples of hazard-prone housing acquisition (or buyout) processes, based on four legislative mechanisms: special legislation (Canterbury Earthquake Recovery Act 2011), the...

An empirical model for attributing sources of particulate matter

Perry K. Davy & W. B. Trompetter
Airborne particulate matter (PM) pollution is well-known to have significant adverse effects on human health. It also has a range of environmental effects, including local reductions in visibility, effects on the radiative balance and deposition of contaminated material onto land and waterways. Because of these effects, PM concentrations are routinely monitored in numerous countries and managed according to local legislation. In New Zealand, the National Environmental Standard (NES) for PM sets a 24-hour average limit...
