Flood hazard areas

Greater Wellington provides flood hazard advice to people across the Wellington Region, helping you to identify potential flood hazard on your property, and provide advice on appropriate development in flood hazard areas. This app helps people understand if they live in an area that could be impacted by flooding. It’s also used to inform district planning. We also provide flood hazard information for the rivers and streams we maintain, and 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. Note that local district plan rules apply when buying, selling, or developing in a flood hazard area.
