Local councils name streets and allocate property numbers; and also change them. Toitū Te Whenua works to ensure that the numbering and addresses meet the requirements of good addressing practice.
We maintain the official national record of all road names and property numbers in New Zealand. We assess all numbering and naming proposals from councils against the national standards and guidelines before adding them to the official record.
These addressing standards and guidelines help to ensure addresses are unique, logical and clear, with odd numbers on the left, and even on the right – all factors that help avoid confusion.
A range of different organisations use the data making up that national record in the delivery of their services. This data is available for free through the LINZ Data Service.
