Overview
PropData New Zealand normalizes authoritative New Zealand property-source layers into a country-aware property contract. The current national graph contains 3,040,571 primary parcels, 2,424,415 authoritative addresses, 2,450,998 property titles, and 2,988,279 title↔parcel associations. The LINZ building-outline baseline targets 3,268,141 outlines and is actively loading as a separate enrichment layer.
Quick start
Use country=NZ on New Zealand property requests.
Address
Primary parcel
Coordinates
The Mabey Road record is a verified production-graph canary: address ID 2064090, primary parcel 3818618, appellation Lot 1 DP 90132, Wellington land district.
Authentication
Direct PropData requests use an API key supplied in the x-api-key header. Keep direct production keys server-side.
RapidAPI subscriptions use RapidAPI marketplace credentials once the New Zealand listing is promoted. Direct PropData keys and RapidAPI credentials are separate.
Property lookup
Resolve a New Zealand property by authoritative address or primary parcel identifier.
| Parameter | Required | Description |
|---|---|---|
country | yes | Use NZ. |
address | one input | Full NZ address. Use instead of parcel. |
parcel | one input | LINZ primary parcel ID such as 3818618. |
Parcel-level output can include fields such as:
Coordinates → property
| Parameter | Required | Description |
|---|---|---|
country | yes | NZ |
lat | yes | WGS84 latitude. |
lng | yes | WGS84 longitude. |
Coordinate resolution is designed to attach spatial property context without pretending that every point maps to an exact address string.
Property title graph
The title layer is not a scraped ownership blob. PropData maintains national title records and explicit title↔parcel associations from LINZ.
| Layer | Rows | Status |
|---|---|---|
| Property titles | 2,450,998 | National baseline complete |
| Title↔parcel associations | 2,988,279 | National baseline complete |
Verified title records attached to the Mabey Road parcel include fields such as:
number_owners.Parcel geometry
Primary parcel records can carry GeoJSON-compatible polygon geometry, bounding box and area context. Useful parcel fields can include geometry, bbox, centroid, calc_area, survey_area, topology_type, parcel_intent, statutory_actions and affected_surveys where the source supports them.
LINZ building outlines
New Zealand building outlines are a separate national enrichment layer. The current target is 3,268,141 building outlines; the baseline is actively loading and should not yet be interpreted as identical coverage on every property response.
Published source metadata can include:
Country capabilities
Returns the country-aware PropData framework and capability context across supported markets. Layer availability remains country-specific.
Health
Public production service health.
Platform statistics
Public platform proof points. Do not use global statistics as a substitute for coverage fields on an individual property response.
Changelog
Production API and data-platform changes.
Match & coverage semantics
PropData is intentionally fail-closed. A property response can distinguish successful identity resolution from downstream layer availability.
| Signal | Purpose |
|---|---|
match_level | How the input resolved, such as address, parcel or coordinate. |
coverage_status | Explicit source/layer coverage state. |
parcel_resolution | Whether an address or location attached to parcel identity. |
| source identifiers | Preserve LINZ-native IDs and PropData canonical IDs. |
| provenance | Keep authoritative-source context visible after normalization. |
Errors & retries
| Status | Meaning | Recommended behavior |
|---|---|---|
| 400 | Invalid request | Correct parameters before retrying. |
| 401 | Authentication failed | Check credentials. |
| 404 | No matching resource | Treat as a resolution outcome. |
| 429 | Rate/quota exceeded | Honor retry and plan limits. |
| 5xx | Server/upstream failure | Retry with bounded exponential backoff. |
Sources & attribution
Core New Zealand property layers are sourced from Toitū Te Whenua Land Information New Zealand (LINZ). PropData maintains the ingestion, normalization, canonical identity, relationship graph, spatial processing, coverage semantics and production delivery above those source systems.
The current LINZ building-outline layer is attributed under its published open-data terms. PropData preserves source attribution and capture provenance in the normalized layer where available.
PropData is an independent product of PropTechUSA.ai and is not operated by or affiliated with LINZ or the New Zealand government.
