New Zealand Business Number (NZBN)

The New Zealand Business Number (NZBN) is a unique 13-digit identifier that will make doing business with the Transport Agency easier and faster.

What is a NZBN?

A New Zealand Business Number (NZBN) is a globally unique 13-digit identifier that is available to all NZ businesses free of charge.

It holds all of a business’s correct information in one place – one-stop-shop – thereby removing the risk of having old information stored in multiple places.

The main purpose of a NZBN is to make doing business easier and faster.

When you share your NZBN with the Transport Agency, we will be able to access your core business information such as your trading name, entity type, status, address and contact details.

The video below explains more about the NZBN:

Why are we integrating NZBN?

The NZBN was established under the Government’s Better Public Services (BPS) programme, designed to drive reforms to ensure high quality, flexible and cost-effective public services.

Under the New Zealand Business Number Act 2016, the Minister of State Services and the Minister of Finance issued a ministerial direction which directed the Transport Agency to support a whole of government approach to the implementation of the NZBN.

We will actively use the NZBN to reduce the time and effort people in business spend dealing with the Transport Agency, now and into the future.

How are we using NZBN?

We have embedded the NZBN into all of our core systems, i.e. motor vehicle register (MVR), driver licensing register (DLR), and systems, applications and products (SAP). When business customers provide their NZBN we will be able to validate their information faster and more easily.

If you have a question about the NZBN programme please email with the subject heading ‘NZBN’ and we’ll endeavour to provide an answer as soon as possible.
