Dunedin City Council – Kaunihera-a-rohe o Otepoti

This map shows all the navigable roads in the Dunedin City territory, along with all the primary physical addresses of all Dunedin properties.

We are the authority primarily responsible for road and address information within the city. We manage all changes to property numbering and road naming, and this map is regularly updated with these changes.

We advise other agencies of changes including Emergency Services, Land Information New Zealand, NZ Post. We also regularly provide updates to map publishers and data providers such as those used for website maps and vehicle navigation systems. It can take several weeks for these agencies and providers to update their systems and provide their customers the updated information.

How is the physical address of a property determined?

A physical address is made up of a) a property number, b) a road name and c) a locality name (or names).

a) Property numbers

We assign or approve these numbers (Local Government Act 1974 Sec 319B (1) and Roading Bylaw 11.10). We use industry standards as a basis for determining the numbering. For example, for rural numbering, the RAPID system is used where the numbering is based on the distance from the start of the road (e.g. the entrance to 125 is located approx 1.25km along the road on the left).

Can existing numbers be changed? – Yes.

If a property owner requests a change to the property number, and it complies with the standards, then we will usually approve the change. We are reluctant to force change onto property owners and will only do so if absolutely necessary. This may occur with a road realignment, where two properties have the same number, or other circumstances where there is real risk that emergency services could have difficulty locating the property.

b) Road names

We name new roads, and can also alter the name of an existing road or assign a road name to previously unnamed roads (Local Government Act 1974 Sec 319(j)). New roads are often created along with a new subdivision and the developer will propose names for new roads to the Council. The Council makes the final road naming decisions following the Council Road Naming Policy, with supporting Guidelines.

c) Locality names

Locality names are needed to uniquely identify properties by address. This is because of the many duplicate road names that exist in New Zealand. In fact, of the 2260 named roads within the Dunedin City territory there are 339 roads that have duplicate names elsewhere in the city. There are five road names that each have four separate roads with the same name (Clyde Street, Brown Street, Queen Street, Cemetery Road, Main Road). Many of the duplicate road names occur between the old Dunedin city roads (pre 1989) and former borough roads (Mosgiel, Port Chalmers, Waikouaiti, etc). By adding the name of the locality, the address becomes unique.

There are many suburb names in the central part of the city (Mornington, Opoho, Brockville, etc) and while these are not essential for uniqueness, they help locate the part of the Dunedin the road or property is within. The general location of suburbs is recognised by the DCC and most appear on the street map.

The boundaries of suburbs are not defined in any authoritative sense, and there may be a number of options for suburb names for a property addresses that can be considered valid, and are subject to personal preference.

Mailing Addresses

Mailing or postal addresses are assigned by providers of mail delivery services. While, in many cases, the physical address is used as a component of the mailing address, other information and formatting requirements are required by the provider.

In New Zealand, this is usually NZ Post. Local authorities have no control over mailing address requirements, except that where property numbers are displayed at the property for mailing purposes, these must be those numbers allocated by us. We regularly work with NZ Post to ensure this is the case. Other aspects of the full mailing address, such as its format, building names, suburb names and post codes are issues for NZ Post.

We maintain many lists of mailing addresses (such as for rate payers and dog owners) and we regularly audit the mailing address data with NZ Post to ensure they are as accurate as possible.
