When a Resource Consent is issued, the council sends a copy of the approved survey plan with the new numbers to the owner of the property, and to Land Information New Zealand.
Properties that have never had street numbers are gradually being numbered to assist with property identification for mail delivery, services such as telephone and power, and emergency services.
Urban street numbers are allocated sequentially e.g. 1,3,5, on the left hand side and 2,4,6, on the other. Rural house numbers are allocated using RAPID numbers.
Street numbers are allocated pursuant to Section 319B of the Local Government Act 1974.
In new subdivisions it is Council policy to allocate numbers sequentially; no numbers are missed out. Consequently, it is not possible to change a street number if the only reason is that the owner of the property does not like the number.
Corner properties in a new subdivision are allocated 2 numbers, one for each road to allow for access from either road. The number selected (as primary address) is dependent upon the vehicle access and letterbox being sited in the appropriate street. Similarly, large properties may have multiple addresses to allow for future development.
In older streets, there are sometimes problems with street numbering. The Property Information Officer can investigate this.
Renumbering of existing dwellings is avoided where possible, but occasionally where areas have been closely subdivided the old numbers become duplicated and illogical, and re-numbering is required.
This will obviously not be done without very good reason, and it will generally not be possible for people to retain their old numbers.
Street numbers for multi unit developments (ie, no subdivision, cross-lease or unit title) can be pre-numbered as Premise Properties.
