Where does the address information come from?

Australia

The address data we use comes from two main sources. These are the G-NAF address database and the Australia Post PAF (Postal Address File).

The G-NAF database is owned, created and maintained by the PSMA (an Australian Government owned company) who source their address data from ten authoritative sources including State and Territory Governments, the Australian Electoral Commission, the Australian Bureau of Statistics and other Commonwealth sources. The G-NAF database is updated quarterly.

The Australia Post PAF is owned, created and maintained by Australia Post. From the PAF we get the database of all Australian addresses to which Australia Post deliver mail. This also includes PO Box types addresses. The PAF is updated monthly.

Lastly, the Australian Bureau of Statistics also contribute data as they provide the meshblock information associated with each address.

New Zealand

The address data we use to to build and provide the Addressfinder service comes from five different sources:

1. The New Zealand Post Postal Address File (PAF). From the PAF we collect all New Zealand addresses to which New Zealand Post deliver mail. This also includes urban business and residential addresses, rural addresses and PO Box type addresses.
2. The NZ Addresses dataset owned, maintained and supplied by Toitū Te Whenua Land Information New Zealand, and contain addresses for all New Zealand properties.
3. Census data from Statistics NZ from which the meshblock associated with each address is obtained.
4. The NZ Localities dataset owned, maintained and supplied by the New Zealand Fire Service, which defines city and suburb boundaries.
5. Addressfinder customers and the general public who submit addresses directly to us. These are typically new addresses which are yet to appear in the official sources. These addresses are verified by Addressfinder staff prior to being included in the dataset.
