If you're planning drainage work, investigating a blocked pipe or reviewing a Napier property, first identify whether you need private drainage records or public network information. Property-level drawings, where held, can differ from asset maps showing nearby wastewater and stormwater infrastructure. We start from the selected address and document type; available records depend on what the relevant authority retains.
Private drainage drawings, where held, record the wastewater and stormwater pipes within a property and their connection to the public system. Napier's mix of older character homes and newer development means record coverage varies considerably from property to property.
Asset maps showing nearby wastewater and stormwater infrastructure answer different questions from property-level drawings. Whether private and public features appear on one plan depends on the type of source record the authority holds.
Homeowners planning renovations or new driveways, plumbers tracing blockages, builders checking sites before earthworks and buyers doing due diligence all request Napier drainage records. The right record depends on whether the question concerns private pipes or the public network.
Search your Napier address above and select the property. We identify the relevant authority and show the available request categories with pricing before you confirm. Available records depend on what the authority retains for the individual property.
There is no guarantee that every property has a recorded drainage drawing. Records depend on what was submitted and retained over the property's history, and any drawing is a historic record rather than a current survey — use utility locating before excavation.
Drainage Plans NZ is an independent third-party document sourcing service, not a council or utility. Records vary and availability must be verified for each property. Plans and network maps are not a substitute for on-site locating or before-you-dig procedures.
