NZ Business Number (NZBN)

Launching a business in New Zealand? If you’re considering undertaking business activity in NZ, one of the initial steps you’ll need to take is acquiring a New Zealand Business Number (NZBN).

In fact, this may very well be the first thing you do, even before formulating a business plan.

Registering for a NZ business number is a requirement by law for all persons and entities engaged in recognised business activities. You cannot legally trade in New Zealand without one.

What is a New Zealand Business Number (NZBN)

What is a New Zealand Business Number and why do you need one?

In New Zealand, a business entity currently operating as either a sole trader, partnership, company, or trust, is required to register for and retain an NZBN to legally trade.

If you’re undertaking business dealings in NZ without an NZBN, you’re doing so illegitimately and without government permission.

Do I need a New Zealand Business Number?

If there’s any confusion over your status as a business in New Zealand (and your requirement to attain an NZBN), refer to the NZ Government’s definition:

“You’re in business, as defined by the New Zealand Business Number Act 2016, if you acquire or supply goods or services, or acquire or dispose of land (but not if you do this as a consumer, employee, or as an individual member of an unincorporated entity).”

If this describes you, then you must have an NZBN.

How to get a New Zealand Business Number

Luckily, for any person or entity looking to do business in New Zealand, the process of gaining an NZBN is simple and straightforward. There are slightly different criteria and burdens of proof required for:

• sole traders
• partnerships
• trusts
• companies

If you’re unsure of which business structure to choose, please refer to the click-through guide provided by the NZ Government here.

Let’s outline the differences of each business type and how to go about applying and registering your business with the NZ Government.

NZBN application

The most reasonable and simple method for applying for an NZBN is through an online application. If you’re the responsible party for the business, you can easily do this yourself.

Alternatively, you can nominate a recognised party to do this on your behalf, such as your accountant or bookkeeper.
