Flow Path Details
FloodMap.nz Interactive Map BETA
This interactive map is provided by FloodMap.nz (a data product of SAE Ltd) as a general reference tool. By continuing you agree to the Terms of Service.
Beta Status
This map is in beta. All data is currently under review and must not be relied upon for any purpose. Layers may change or be updated without notice.
No Reliance
This map is for general informational purposes only. It does not constitute professional engineering advice and must not be relied upon for:
Resource consent or building consent applications
Property purchase or investment decisions
Flood risk assessment or insurance purposes
Design of stormwater infrastructure or earthworks
Accuracy Limitations
Overland flow paths are derived from LiDAR terrain modelling, not field-verified survey
The model does not account for stormwater pipe networks, culverts, or constructed drainage
Results may differ from council-published flood hazard maps
LiDAR surface imperfections may produce artefacts in flat or heavily developed areas
Property Representation
The display of a flow path on or near any property is a modelled terrain estimate only. It does not constitute an authoritative flood record, LIM entry, title encumbrance, or finding that a watercourse exists on that land. For authoritative flood information for a specific property, obtain a LIM report from your council. If you believe data shown for your property is incorrect, email info@subeng.nz.
Limitation of Liability
FloodMap.nz (SAE Ltd) accepts no liability for any loss, damage, or cost arising from the use of or reliance on this map. Use is entirely at your own risk. To the maximum extent permitted by New Zealand law, all warranties (express or implied) are excluded.
Professional Advice
