New Zealand Active Faults Database: 1:250,000 scale (NZAFD-AF250)
The dataset represents the most current mapping of active faults for New Zealand in a single database, designed for portrayal at 1:250,000 scale. It is produced by GNS Science and derived from the QMAP Geological Map of New Zealand Project and the high-resolution New Zealand Active Faults Database (NZAFD-HighRes).
Active faults are defined as those that have ruptured and/or caused ground surface deformation during the last 125,000 years (except for in the Taupō Volcanic Zone / Taupō Rift, where the definition of activity is restricted to only include the last 25,000 years). This dataset includes only onshore active faults, with the exception of offshore faults that ruptured during the 2016 Kaikōura earthquake.
The 1:250,000 scale NZ Active Faults Database (NZAFD-AF250) is a feature class in vector format stored in a PostrgeSQL database. It comprises polylines, with each line representing the location of an active fault trace at or near the surface. Each fault trace has attributes that describe its name, orientation, displacement, sense of movement, time of last movement and other fault activity parameters.
The dataset is published to the GNS ArcGIS server as a web service layer which is intermittently updated with new information. The data can also be viewed through the NZAFD website and downloaded from there in shapefile, KML, JSON and text formats; however, these are not updated as frequently as the web service and are static copies of the database with the timestamp in the file name.

The NZAFD-AF250 is published as the '1:250 000 Active Faults' layer in a combined web service at https://gis.gns.cri.nz/server/rest/services/Active_Faults
The layer only turns on when zoomed out for viewing at a regional scale. For more information on the web service see https://doi.org/10.21420/wa26-0n32?x=y

Data simplified from the high-resolution New Zealand Active Faults Database (NZAFD-HighRes) and QMAP Geological Map of New Zealand Project for use at 1:250,000 scale. Parent data were digitised using a variety of methods: air photo (various scales); differential GPS; field GPS; LiDAR; map (various scales); orthophoto; and survey. Data are peer reviewed by GNS Science and attributes verified for logical consistency by GIS operator. Data are updated as needed and released as a web map service intermittently. The data can also be viewed through the NZAFD website and downloaded from there in shapefile, KML, JSON and text formats; however, these are not updated as frequently as the map service and are static copies of the database with the timestamp in the file name. A Data Dictionary (Langridge et al. 2014) and journal article (Langridge et al. 2016) are published on the background, structure and content of the database.
