The PAF is Addy's master address data source.

When you autocomplete, validate or clean addresses, you have the option to assign a DPID to each customer address in your database. The DPID, which is a unique number of up to seven digits, simplifies the process of identifying duplicate customer addresses. De-duplication (de-dupe) will optimise data storage by eliminating duplicate copies of data and enable you to get a single view of your customers. A single customer view, also referred to as "Known Your Customer" (KYC), enables your business to understand who and where your customers are.


Using the Delivery Point Identifier (DPID), your business can:

  • Allocate the correct postal address to customers
  • Create a single customer view
  • Reduce duplication in your database
  • Reduce the number of duplicate letters sent to the same customer or household
  • Accurately identify the number of unique customers you have
  • Match your address data with third party lists (e.g. New Zealand Business Number (NZBN)) for prospecting and direct marketing campaigns

Address results are returned in a standardise format in accordance to NZ Post's address formatting guidelines to reduce returned or undelivered mail, and help your organisation to become eligible for Bulk Mail rates through the Statement of Accuracy (SoA) Programme.


Access the PAF data via the Address APIs:

  • Use Addy's address finder API to retrieve addresses based on partial address segments (search criteria).
  • Use Addy's address detail API to retrieve detailed address information using the DPID.


Geo Postal Address File (GeoPAF)

Data Source Name Geo Postal Address File (GeoPAF)
Data Supplier New Zealand Post
Update Frequency Quarterly (January, April, July and October)
Content Geo coordinates in WGS84 format (X Longitude and Y Latitude), Meshblock (Stats NZ), Parcel ID (LINZ)
Number of Records Over 2 million
Identifiers
  • X and Y geocode pair (Longitude and Latitude)
  • Meshblock
  • Parcel ID
Address Services Address Detail API, Geocode Address API, Bounding Box Address API, Discovery Address API

The GeoPAF is Addy's master geocoding address data source.


Each address has map coordinates which can be used for:

  • Visualising customers on a map (e.g. insurance companies analysing risks)
  • Group customers by region and area (e.g. targeting the right customers you need to engage)
  • Enable better emergency, pick-up and delivery services (e.g. route optimisation and accurate pin point locations)

The Parcel ID provides a link to the Property and Land Titles database maintained by Land Information New Zealand (LINZ). A Parcel ID can be tied to a polygon area, appellation (legal description), purpose, size and a list of legal titles associated with a parcel.

The Meshblock provides a link to the smallest geographic unit for which statistical data is collected and processed by Statistics New Zealand (Stats NZ). Match your customer addresses to a Meshblock for rich insights into New Zealand households using census information. Use the Meshblock to enrich your customer data for greater target marketing with over 50 demographic characteristics such as income, age group, occupation, number of children and more.


Access the GeoPAF data via the Address APIs:

  • Use the Address Detail API to retrieve detailed geocoding, Parcel ID and Meshblock address information.
  • Use the Discovery Address API to retrieve a list of addresses linked to a LINZ Parcel ID or Stats NZ Meshblock.
  • Use the Geocode Address API to retrieve addresses from GPS coordinates for reverse geocoding.
  • Use the Bounding Box Address API to retrieve a list of addresses from a polygon shape of coordinates.
