This Feature Class contains polygon features that summarise the exploration potential of the Miocene succession within sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins). Areas where all of the requirements for oil or gas accumulation are present are indicated as having high exploration potential. Areas where all the requirements are not optimum, but may be present are indicated as areas of moderate exploration potential. Areas of low exploration potential indicates that on the basis of currently available open-file information there is a high risk for one or more of the petroleum systems elements not being able to effectively contribute to the petroleum system in that area. It is important to note that a rating of low exploration potential does not conclusively rule it out; rather, there is a high degree of uncertainty associated with presence of one or more of the petroleum system elements. For any given prospective area, more detailed work and data acquisition would be required. For more information about these data please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016.

This Feature Class contains paleogeographic structural polyline features for sedimentary basins in the Northwest Province (Atlas of Petroleum Prospectivity), namely the Taranaki, Deepwater Taranaki, and Reinga-Northland basins. Features are depicted relative to the modern New Zealand coastline. No palinspastic reconstructions have been undertaken. Polygon features for 98 Ma (mid-Cretaceous, NZ Ngaterian Stage) are contained in this Feature Class.

This Feature Class contains contours that depict the interpreted depth below sea level (in metres) to the Basement seismic horizon, in 500 m intervals, as mapped within the Northwest Province of the Atlas of Petroleum Prospectivity (namely the Taranaki, Deepwater Taranaki, and Reinga-Northland basins). For more information about the seismic horizon naming scheme used in this project please refer to: Strogen, D.P.; King, P.R. 2014. A new Zealandia-wide seismic horizon naming scheme. Lower Hutt, NZ: GNS Science. GNS Science report 2014/34. 20 p. The depth grids, from which these contours were derived, were generated in Paradigm 2015 SeisEarth software using an adaptive fitting algorithm and a grid resolution of 1 km x 1 km. Faults have not been incorporated into the regional-scale gridding of either the TWT or depth maps in this project. The depth grids were then exported from SeisEarth (Zmap format), checked for internal consistency in Zetaware (Trinity 4.61), edited as needed to account for gridding errors and then exported as ArcView Ascii grids, imported and contoured with Esri's ArcGIS software. Due to its large depth range the Basement horizon has been contoured at both 250 m and 500 m intervals. For more information about the depth conversion and gridding process used, please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016. Atlas of Petroleum Prospectivity, Northwest Province: ArcGIS geodatabase and technical report. GNS Science Data Series 23b. Given the considerable variability in the spacing and density of 2D seismic data over the entire NWP area the "smoothness" of the depth maps varies accordingly. In the central Taranaki Basin, where seismic line spacing may be 5 km or less, the 1 km x 1 km grid resolution captures the geological complexity well. However, in areas of the NWP such as the Deepwater Taranaki Basin to the west and Reinga Basin in the north, seismic line spacing may be in the order of 15 to 30 km. In such areas the underlying geological complexity is only captured where seismic interpretation exists along the available 2D seismic lines.

This Feature Class contains Common Risk Segment (CRS) polygon features for denoting the risk of reservoir rocks being absent at the 66 Ma (latest Cretaceous) level in sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins). Risk is depicted by a relatively simple "traffic-light" system: green colours denote low risk, orange denotes moderate risk, and red colours denote high risk. It is important to note that a rating of high risk (red) for this petroleum systems element does not conclusively rule it out; rather, it indicates that on the basis of currently available open-file information there is a high risk for that factor being able to effectively contribute to the petroleum system in that area. For any given prospective area, more detailed work and data acquisition would be required. For more information about these data please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016.

This Feature Class contains Common Risk Segment (CRS) polygon features for denoting the risk of reservoir rocks being absent at the 14 Ma (Middle Miocene) level in sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins).

Active fault traces mapped using 1 m resolution Light Detecting and Ranging (LiDAR) Data commissioned in 2013 by Greater Wellington Council. The revised mapping is focused on previously-mapped faults and near towns in the Wairarapa Valley. From these fault traces, Fault Avoidance Zones have been developed for faults in and around the main towns and selected previously mapped faults, and Fault Awareness Areas for the remainder. The mapping was undertaken for land use planning purposes as one natural hazard dataset for a revision of the Combined District Plan. Cite data as: Litchfield, N. J., Coffey, G. L., & Morgenstern, R.
