What's an NZBN?

The New Zealand Business Number (NZBN) is a single, unique identifier specifically for your business. It’s a way for your business to identify itself both in New Zealand and globally. Come and explore the NZBN and see how and why it’s a business asset, not just a number.

Check out our video, it explains more about the NZBN.

Who can have an NZBN?

The NZBN is for all Kiwi businesses – large or small - including:

  • Self-employed people (otherwise known as sole traders) such as midwives, lawn-mowing contractors, landlords etc.
  • Partnerships
  • Trusts
  • Companies
  • Public sector entities – such as government agencies and local authorities
  • Other corporate and public entities

If you’re in business in New Zealand, an NZBN is for you.

New Zealand companies and public sector entities already have their NZBN.

If you're not carrying out business in New Zealand  you can’t get an NZBN.

Whether your business operates from the kitchen table at home, or you’re a large multi-national with global interests, you can get an NZBN.

Getting and using your NZBN can make it easier and faster to inform, connect and transact with other businesses and government, by helping to streamline time-consuming business processes such as invoicing and procurement.

How an NZBN works for you

Your NZBN links to your core business information (called your Primary Business Data), which is held securely online on the NZBN Register. The more information you make publicly available the better your NZBN can work for you, and the less work you’ll have to do to keep everyone informed.

One central register for your business information

Other businesses and government agencies can use your NZBN to access your core business information, since it’s all in one place on the NZBN Register. This not only identifies yours as a legitimate business, but will save you time and money – you won’t have to repeat the same information over and over again.

You’ll be able to plug into a shared network of information, opening up all sorts of business possibilities and saving you time. You can also see and use other organisations’ NZBN details, speeding up many business processes, such as procurement and invoicing.

More NZBNs - easier business

As more businesses begin using their NZBN and start to share information, it will open up a new world of possibilities. You’ll be able to see supply chains, build trusted networks, find and assess providers, improve customer service and a whole lot more.

The more core information you make publicly available, the easier it will be for other businesses and government agencies to connect with you, which ensures you get the most out of using your NZBN.

Using your NZBN will also reduce the time and energy you spend providing government the same core business information multiple times in a variety of ways. For example, over time when you’re dealing with ACC and Inland Revenue, you’ll update your business information just once, via the NZBN Register, where government agencies can access it.
