Rising tide interactive location3/21/2024 Areas around Wellington Harbour were updated in 2021 based off updated LIDAR elevation datasets from HCC (2016) and WCC (2020). The survey data was subsequently reprocessed in 2017 by Landcare Research with funding from LINZ. This was based off a laser airborne (LIDAR) survey commissioned by the WAGGIS consortium in 2013. The basis for this mapping is a detailed digital elevation model (DEM) of the Wellington Region. Tide level offsets are based on values in a report produced by NIWA for the Parliamentary Commissioner for the Environment in 2016. Inundation areas were modelled in 2017 based off a detailed digital elevation model (DEM) of the Wellington Region. ![]() Alternative map overlays show modelled storm surge flooding at different sea level rise values, for a 1% AEP (100 year) event. ![]() This webpage displays a dynamic map which shows the calculated inundation areas at a range of sea level rise values in the Wellington Region.
