Street address data content requirement

Purpose of requirement

The purpose of this requirement is to mandate the ISO 19160-1:2015 Addressing Part 1: Conceptual Model to be used to format street address information for sharing purposes.

This data content requirement applies to data being shared between organisations.

This data content requirement does not mandate the format for postal address or location. Nor does it mandate the storage or collection of street address.

ISO 19160-1:2015 Addressing Part 1: Conceptual Model

Definition

An address is structured information that allows the unambiguous determination of an object (that may be assigned an address) for purposes of identification and location.

An address allows us to:

  • locate buildings, places, people, and events
  • deliver and receive goods and services
  • enable analysis by connecting information
  • provide a location.

Compliance

The minimum required format for compliance when sharing address information is 3 mandatory data elements and 1 conditional data element in separate fields:

  • Number
  • Road name
  • Suburb/locality
  • City/town name.

For example, the address 19 Rimu Road, Crofton Downs, Wellington comprises the number along the road (19), the name of the road (Rimu Road), the locality the address is physically located in (Crofton Downs), and the city or town (Wellington).

The data content requirement for street address uses underpinning concepts from ISO 19160-1:2015 Addressing Part 1: Conceptual Model.

Guidance

Number

Number is the unique number given to a property on a named street, usually assigned in a sequential order from the start of the street. A street address must include a number where possible. The exception is where a number is substituted with a building name (eg The Beehive).

A number can also include a unit (or flat) number or an alpha suffix. A unit number should come before the number and be separated from it by a '/' (eg 1/21 for unit 1). An alpha suffix should come after the number and not be separated from the number by a space or any other character (eg 21A).

Road name

Road name is the name of the road an address is on. It can be made up of a number of fields: prefix, name, road type, and suffix. A road name should include at least a name and a full, non-abbreviated road type (eg road, street, avenue). In cases where a road name does not include a road type (eg The Terrace) the road type may be omitted.

Suburb/Locality

A locality is a named geographical area (place name) defining a community of interest and may be rural or urban. (Urban localities are commonly called suburbs.) The most common localities dataset is NZ Localities maintained by Fire and Emergency New Zealand. This dataset provides non-overlapping, contiguous coverage of all New Zealand’s land area.

To comply with this requirement a street address must include a locality to ensure that each address is unique. 

City/town name (conditional)

Where a suburb or locality does not make each address unique, an address will additionally require a city or town name that should be provided in separate fields to the locality.

Other fields

Where other street address elements such as postcode are shared, these should be recorded in separate fields.

Further information

A New Zealand draft profile of ISO 19160-1 will be incorporated into this data content requirement when completed.
