Coastal & tsunami risks
Storm surge, sea-level effects, and civil defence evacuation mapping for Auckland’s coast.
Harbour-side, beach-front, and low-lying coastal properties face different risks from the open ocean. iQHOME checks two council layers: coastal storm inundation and tsunami evacuation zones.
Coastal storm inundation
Mapping for flooding from storm tides and elevated sea levels combined with severe weather. Relevant for properties near the Waitematā, Manukau, Kaipara, and east coast beaches where waves and surge can push water inland.
Tsunami evacuation zones
Civil defence zones showing areas that may need evacuation in a tsunami event. These include shore and land-threat zones. They are planning and safety maps, not predictions that a specific property will flood in every scenario.
- Insurance availability and premiums can differ on coastal land
- Long-term sea-level rise may affect planning and resilience rules
- Evacuation zones matter for safety and civil defence planning
If coastal layers appear on your report, review Auckland Council coastal guidance, ask your insurer early, and understand evacuation routes. iQHOME summarises mapping at your pin; it does not model future climate scenarios for your specific building.
