This data should be treated as public infrastructure, not as a proprietary product.
Postal codes, regions, and town mappings are foundational geographic data. They are used for addressing, emergency services, public planning, education, logistics, and digital services. This is the same category as road names or suburb boundaries. It should not be owned, licensed, or restricted by a company.
The argument that the data “changes frequently” is not a valid reason to withhold it. Many public datasets change regularly (addresses, roads, boundaries, electoral boundaries) and are still published openly. This is already standard practice internationally.
In many other countries, this exact type of data is publicly available.
New Zealand is an outlier here, not the norm.
NZ Post does not generate this data in isolation. It exists because of government-defined geography, local councils, national addressing standards, and public infrastructure. If the government relies on this data internally, the public should have access to the same data under an open licence.
Treating postcode data as a licensed commercial product creates unnecessary barriers for developers, researchers, startups, and even other public-sector users. It leads to duplicated unofficial datasets, inconsistencies, and worse outcomes overall.
This data should be published as open data, with free public access and no restrictive licensing.
Postal codes are public infrastructure. They should not be monetised, gated, or treated as corporate property.
