This property has been assessed across 5 natural hazard categories using publicly available Auckland Council, GNS Science, and NIWA data. The overall score reflects the highest individual hazard score across all categories.
This property falls within a mapped flood plain. During a 1-in-100 year rainfall event, modelling indicates water depths up to 0.4 m are possible across the lower portion of the site. The risk is elevated by proximity to a local catchment channel approximately 180 m to the north.

Under a 1 m sea-level rise scenario combined with a 100-year storm surge, inundation is not projected to reach this property. The site sits approximately 1.8 m above the modelled inundation boundary. Risk may increase under higher sea-level rise projections beyond 2100.

An overland flow path traverses the rear of the site. During heavy rainfall events, surface runoff from the catchment to the south is channelled across this path before discharging to the road reserve. Building structures within this corridor is restricted under Auckland Unitary Plan rules.
📊 Data source: Auckland Council GIS — Overland Flow Paths FeatureServer
The property is partly located within a flood-prone area designation under the Auckland Unitary Plan. This overlay indicates susceptibility to ponding or inundation from local stormwater systems during intense rainfall. Development within this overlay requires assessment of flood risk.

Based on the Auckland Susceptible Coastal Infrastructure and Erosion (ASCIE) 2130 RCP8.5+ projections, the property is outside the coastal erosion hazard area. No significant coastal erosion risk is identified for the site within the current modelling horizon.
