Porirua is exposed to a range of geological natural hazards. These include liquefaction and land instability (landslides). To better understand the extent and nature of the liquefaction and land instability hazards within Porirua, we are seeking to procure district-wide geotechnical assessments from suitability qualified and experienced geotechnical professionals.

The Liquefaction and Landslide Assessment Reports and Mapping opportunity aims to provide Porirua City Council with relevant, accurate and accessible information on these geological hazards to inform our statutory processes as well as future land use planning and asset management. When we refer to the ‘assessment reports’, we mean geotechnical reports and associated mapping that will assess the vulnerability, susceptibility, hazard, or risk of liquefaction and land instability within Porirua, as the case may be.
