Integrated 3D petroleum generation, migration and charge modelling in the Kupe-Kapuni region, south-eastern Taranaki Basin

Karsten F Kroeger, Rob H Funnell, M Fohrmann & Matt G Hill
This report presents workflows and results of integrated petroleum systems modelling of the Kupe region in the south-eastern Taranaki Basin. A series of PetroMod™ 3D models have been built for numerical forward modelling of the complex tectonic and sedimentological evolution of the area. The models use a detailed structural and stratigraphic model based on high-resolution grids (100 x 100 m) developed from new reflection seismic data interpretation carried out as part of the GNS 4D...

Classification of New Zealand hydrogeological systems

Magali Moreau, Paul A. White, Frederika Mourot, Zara J. Rawlinson, Conny Tschritter, Stewart G. Cameron & Rogier S. Westerhoff
Digital datasets of New Zealand hydrogeological systems and their boundaries have been developed using a nationally-consistent and transparent methodology. Here, we define hydrogeological systems as geographical areas with broadly-consistent hydrogeological properties, and similar resource pressures and management issues. These systems are represented in two Geographical Information System (GIS) datasets at the 1:250,000 scale, i.e., hydrogeological system polygons and system boundary polylines. The hydrogeological system polygons (1896 in total) include attributes corresponding to mapping levels, i.e.:...

Robert R. Reeves & Fiona Sanders
An aerial thermal infrared (TIR) survey of the Waiotapu Geothermal Field was undertaken on 13 April 2019. Approximately 2260 TIR images were processed and mosaicked to produce a single, 16-bit image with a ground pixel size of approximately 2 m x 2 m (Figure A.1). The purpose of this report is to summarise the method of data collection and present the final TIR image and accompanying brief interpretation. The TIR data is of good quality...

The regional gravity field, used to separate the residual gravity anomalies from Bouguer anomalies,...

Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITTS IV)

Laura M. Wallace &
HOBITSS IV was a 12-day (24 June–5 July 2017) Wellington to Wellington R/V Tangaroa voyage (TAN1705). Objectives of TAN1705 were to (1) undertake seafloor geodetic instrument deployments, recoveries, and surveys offshore Gisborne and Mahia, and (2) acquire multicores along the Hikurangi margin and offshore the north-eastern South Island to evaluate the extent of turbidite deposition following the November 2016 Kaikōura earthquake. The seafloor geodetic aims involve using Bottom Pressure Recorders (BPRs) to determine the cm...

Hei koha tū, hei kura huna a papa: a resource characterisation and ancestry of minerals for Ngāti Hako

Mark P. Simpson, P. Clarkin, Anthony B Christie & Diane Bradshaw
Mineral resources have long provided Māori with trading opportunities and growth through innovative developments with those from the Hauraki rohe used and traded by Ngāti Hako; the earliest inhabitants of Hauraki. Basalt from Tahanga was fashioned into adzes and obsidian from Tūhua (Mayor Island) was used as cutting tools; the latter traded throughout New Zealand. Other rocks and minerals from the Hauraki rohe have since become of economic significance (e.g. gold and silver) or are...

Kinematics of the New Zealand plate boundary: field report on GNSS surveys of the Taranaki Network in 2019 (TARA2019)

Rory J. A. Hart & Neville G. Palmer
Between March and June 2019, a combined team from GNS Science and Land Information New Zealand (LINZ) re-measured a network of 109 geodetic survey markers using Global Navigation Satellite System (GNSS) methods throughout the Taranaki and Manawatu regions of New Zealand for monitoring the regional deformation due to tectonic processes. Included in the survey were 13 sites located in the Te Urewera mountains and Raukumara Peninsula that were observed to complete the requirements for the...

Post-earthquake building functionality and habitability in New Zealand: Survey results

Finn R. Scheele, SR Uma, Tatiana Goded, Maureen A Coomer, Nick A. Horspool & Jose Moratalla
The habitability and functionality of buildings following earthquake events has a significant impact on the recovery process. Understanding the factors that influence levels of post-event habitability and functionality can assist in identifying areas for improvement in risk reduction and resilience and allows for improved modelling of social impacts. We developed an online survey to gather data from individuals that had experienced recent earthquake events in New Zealand. Broadly, questions were asked regarding the following categories:...

Geothermal gas emission and its impact on hauora and taiao at Whakarewarewa, the Living Village

Agnes Mazot, R. Huata, Diane Bradshaw, Perry K. Davy, B. Millar, J. Warbrick, J. Davis & Andreas Markwitz
This research explores the effect of Hydrogen Sulfide (H2S), a primary geothermal gas and in a certain extent Carbon Dioxide (CO2), has on humans when exposed to extreme environmental conditions. In this report we document and record the traditional histories/Mātauranga concerning the connection between H2S and the hauora (health) of people at the Whakarewarewa Village. An integrated database helped with the integration of technical, scientific and traditional Māori information, and the support of agile knowledge...

Better spatial characterisation of evapotranspiration and rainfall recharge estimates to groundwater using remote sensing multispectral techniques at lysimeter sites

Frederika Mourot, Rogier S. Westerhoff, Nick Macdonald & Stuart G. Cameron
Regional councils have the responsibility to set up allocation limits to protect and ensure the sustainable use of their freshwater resources. An important part of allocation limit setting consists in assessing the amount of recharge to groundwater. Improvement of recharge models and assessments of sustainable allocation limits will become more important in the context of climate change, where more variable rainfall inputs are expected in the future. This study, commissioned by Envirolink for Hawke’s Bay...

Obtaining water level data at Whakarewarewa Geothermal Valley using unmanned aerial vehicle photogrammetry

Nick Macdonald, Robert R. Reeves, Duncan J. Graham & Thomas Brakenrig
Unmanned aerial vehicles (UAVs) offer a novel means of studying dangerous and inaccessible areas. They have the advantage of having the ability to survey large study areas relatively quickly, while utilising a wide array of sensors. Monitoring the water level of geothermal pools is important for providing insight into how fluids may be flowing and interacting between geothermal surface features and shallow groundwater aquifers. Making manual measurements of water levels in geothermal areas can be...

Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS V)

Daniel H. N. Barker, Laura M. Wallace, K. Woods, M. Savage &
HOBITSS V was a 12-day (6–18 October 2018) Wellington to Wellington R/V Tangaroa voyage (TAN1809). Objectives of TAN1809 were to undertake seafloor geodetic and seismic instrument deployments, recoveries, and surveys offshore the Gisborne, Mahia, and Wairarapa coasts. The seafloor geodetic aims involve using Bottom Pressure Recorders (BPRs) to determine the cm-level vertical movement (upward or downward) of the seafloor during slow slip events and to deploy two new precision transponder arrays to monitor cmlevel horizontal...

Short-term preparation for and response to an impending lava flow: lessons from the June 27th lava flow (2014-2015), Hawaii, USA

S. W. R. Tsang, Jan M. Lindsay & Natalia I. Deligne
On 27 June 2014, a lava flow began erupting from Kīlauea Volcano that eventually threatened the town of Pāhoa, Hawaii, USA. As the lava flow approached town limits, Hawai‘i County Civil Defense led local scientists, government agencies, non-governmental organisations and local businesses in efforts to prepare the town for potential impacts. Key measures included holding at least daily press conferences and weekly community meetings, building three evacuation routes, creating power pole protection structures and building...

CLUES-GW: a simple coupled steady state surface-groundwater model for contaminant transport

Sandy Elliot, Channa Rajanyaka, Jing Yang & Jeremy White
This report presents CLUES-GW, a simple catchment model that provides mean-annual contaminant load estimates in surface water and groundwater. The model was developed by NIWA as part of the SAM (Smart Models for Aquifer Management) research programme, led by GNS Science, which aims to investigate the implications of model simplification for uncertainty and implications for decision-making. CLUES-GW represents an extension of the existing CLUES model —it includes shallow and deep groundwater reservoirs under each surface...
