The vulnerability categories are those set out in the Ministry for Business, Innovation and Employment and Ministry for the Environment's 2017 Planning and engineering guidance for potentially liquefaction-prone land. The liquefaction categories were revised from the liquefaction susceptibility dataset supplied to Environment Canterbury by GNS Science in September 2020 as part of the Waitaki District Plan review. The original 2020 dataset was derived from a Level A (Basic Desktop) assessment using available geological, geomorphological, and groundwater information. In this 2023 dataset we have made minor revisions tothe original 2020polygon boundaries to better fit the detail of the geomorphology interpreted from available lidar and aerial imagery, andhave changed the nomenclature and attribute fields to follow the 2017 MBIE/MfE liquefaction guidance.
