Whanganui District Council — Property Due Diligence Guide
Whanganui District Council governs the river city of Whanganui, with a population of approximately 47,000. The city is built around the Whanganui River, the longest navigable river in New Zealand and a taonga (treasure) of national significance. The river was granted legal personhood in 2017, reflecting its cultural importance to local iwi.

How to Order a LIM Report
Contact Whanganui District Council directly to order a LIM. Standard processing takes 10 working days.
Whanganui LIMs cover building consents, resource consents, rates, zoning, and natural hazards. Given the city's heritage building stock, pay attention to any heritage listings or designations that may restrict alterations.
Properties near the Whanganui River should be checked carefully for flood risk. The LIM will note any flood hazard zones. Also check for any contaminated land entries, as the city has a history of industrial activity.
District Plan Zones
Whanganui's District Plan includes these key zones:
- Residential Zone: Standard residential areas
- Residential Amenity Zone: Higher-amenity residential areas
- Commercial Zone: Town centre and commercial areas
- Rural Zone: Surrounding farmland
- Heritage Precinct: Areas with heritage building protections
Whanganui's district plan includes heritage provisions that protect the character of the city's older buildings and streetscapes.
Natural Hazards
Whanganui's natural hazard profile includes:
- Flooding: The Whanganui River and its tributaries create flood risk in low-lying areas. The city has experienced significant floods historically.
- Land instability: Whanganui's terrain includes steep hillsides and river terraces that can be prone to slipping.
- Coastal erosion: The coastal settlement of Castlecliff faces some coastal hazard risk.
- Seismic activity: Moderate earthquake risk, as with most of the lower North Island.
Building Consent & Code Compliance
Building consent is processed by Whanganui District Council with a standard 20 working day target.
Whanganui's heritage building stock means many renovation and alteration projects involve older construction methods (brick, timber, lathe and plaster). Heritage-listed buildings may require additional consents for alterations. Earthquake strengthening may be required for some older commercial buildings.
Frequently Asked Questions
What should I know about buying a heritage home in Whanganui?
Check the LIM for any heritage listings under the District Plan. Heritage-listed properties may have restrictions on external alterations and demolition. Also check the building's structural condition, particularly for earthquake resilience — some older brick buildings may need strengthening.
How does the Whanganui River affect property?
Properties near the river may be in flood hazard zones. Check the LIM for flood overlays. The river's legal personhood status does not directly restrict property rights but reflects its cultural significance. Discharge and land use near the river is managed by Horizons Regional Council.
