Finding your way somewhere is straight forward when you’ve got the address. Road names and numbers; suburbs, town and city names, all help provide a common understanding of where places – and people – are. Much of daily life depends on it. It’s the basis of delivering mail or courier items. It’s fundamental to civil defence emergency services – fire, police, and ambulance. It’s used for the supply of utilities like power and water. It’s also the basis of things like New Zealand’s voting system. They all depend on accurate, locatable addresses.
It’s the job of local councils to allocate or change property numbers and street names. It’s our job to ensure that the numbering and addresses meets the requirements. We do this by producing addressing standards and guidelines. These require addresses to be unique, to be logical and clear, for odd numbers to be on the left, even on the right – all factors that help avoid confusion.
We also maintain the official national record of all road names and property numbers in New Zealand. We assess all numbering and naming proposals from councils to ensure that they meet the national standards before adding them to the official record.
A range of different organisations use the data making up that national record in the delivery of their services. We make this data available free through the LINZ Data Service.
