We give flood hazard advice to people across the Wellington Region. Our team can help you identify potential flood hazard on your property, and provide advice on appropriate development in flood hazard areas.
We also provide flood hazard information for the rivers and streams we maintain. Local councils also hold flood hazard information. Wellington Water holds stormwater flooding models for areas of Porirua, Wellington, South Wairarapa and Upper and Lower Hutt.
Local district plan rules apply when buying, selling, or developing in a flood hazard area.
Flood hazard maps
We provide two types of flood hazard maps:
- Detailed flood hazard map: This map helps people understand if they live in an area that could be impacted by flooding. It’s also used to inform district planning.
- Regional flood hazard exposure map: This map was created to inform emergency management planning, strategic planning decisions, and for flood hazard advice where detailed mapping does not exist.
