This layer depicts estimated sediment/soil loss across New Zealand and was created using the NZeem erosion model. Erosion control is defined as the prevention of soil loss by an ecosystem. NZeem has been calibrated from sediment discharges measured in New Zealand rivers (Dymond et al., 2010). This model estimates the long-term mean erosion rate from all...

Mean annual erosion rates (tonnes of soil/km2/yr) in the South Island of New Zealand under current landcover generated from EcoSat Woody (2001-2003). This layer is not available for download on LRIS. If you are interested in downloading that layer, please contact John Dymond. Reference: John R. Dymond, Harley D. Betts, Christina S. Schierlitz, An erosion...

The NZLRI is a spatial database containing about 100,000 polygons (map units), each of which describes a parcel of land in terms of five characteristics or attributes (rock, soil, slope, erosion, vegetation). This layer represents a GIS dissolve on the erosion attribute of the NZLRI.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers: NZ Coastlines (Topo 1:50k) NZ Island Polygons (Topo 1:50k) NZ Auckland Is Island Polygons (Topo, 1:50k) NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k) NZ Antipodes Is Island Polygons (Topo, 1:25k) NZ Kermadec...

Coastal Erosion Hazard Zones show the extent of Northland coastlines that are potentially susceptible to coastal erosion.This service shows the location of Coastal Hazards from the 2017 assessment and includes coastal run-up hazard, coastal flood hazard and coastal erosion hazard.

Wellington City Corrosion Zone as determined by NZS 3604:2011. Corrosion Zones relate to the severity of exposure to wind-driven salt, with B being low risk, C medium risk and D high risk (Category A is not applicable in New Zealand). The Wellington City territory authority area is located in zone C aside from the coastal zone. For this reason the coastal...

Service Description: Exposure – the degree to which the shoreline is exposed to wave and swell energy. This variable is further described by 4 attributes: sheltered, exposed, sheltered pocket beach and exposed pocket beach. The geomorphic variables were sourced from the New Zealand coastal type classification scheme and GIS mapping procedures that were...

The Marine Environment Classification (MEC), a GIS-based environmental classification of the marine environment of the New Zealand region, is an ecosystem-based spatial framework designed for marine management purposes. Developed by NIWA with support from the Ministry for the Environment (MfE), Department of Conservation and Ministry of Fisheries, and...

Service Description: The Coastal Sensitivity Index (CSI) provides a snapshot of the potential sensitivity of the New Zealand soft shore coastline to coastal inundation (coastal flooding) and coastal change (erosion and accretion) due to future climate change. The Coastal Sensitivity Index was developed as part of the Coastal Adaptation to Climate Change...

https://gis.niwa.co.nz/arcgis/rest/services/COAST/Coastal_Sensitivity_Index_CSI_erosion/MapServer/ The Coastal Sensitivity Index was developed as part of the Coastal Adaptation to Climate Change (CACC) project. This four-year project funded by the Ministry of Business, Innovation & Employment (MBIE contract C0X0802) was intended to create the...

Gisborne areas susceptible to coastal erosion, coastal flooding and/or tsunami (ASCE) layer as identified in a 2015 study commissioned by the Gisborne District Council. The Gisborne District coastline extends some 500 km from Takararoa in the south to Omaruparoa in the North and comprises some 138 km of sandy and gravel beaches and 202 km of cliffed...

Gisborne areas sensitive to coastal hazards (ASCH) as identified in the Tairawhiti Resource Management Plan. Coastal hazards occur when a natural process has adverse effects on human safety, property or on objects or areas that are valued by humans, or when human activities generate anomalies in natural processes, causing those processes to act in...

Coastal hazards occur when a natural process has adverse effects on human safety, property or on objects or areas that are valued by humans, or when human activities generate anomalies in natural processes, causing those processes to act in unforeseen ways. Human responses to such hazards may, in turn, have other adverse effects on the environment and on...
