The steps to open a business account in New Zealand

The process follows a familiar order. Register the business and its tax identifiers, choose an account that fits how you trade, prepare the documents, then complete identity verification. The detail and the timeline vary between fintech accounts and the major banks, so confirm the current process with the provider you choose.

Register the business and tax identifiers

A company registers with the New Zealand Companies Office and receives a Certificate of Incorporation and a New Zealand Business Number, known as the NZBN. The business also needs its own IRD number from Inland Revenue. Sole traders trade under their personal IRD number and can still get an NZBN. As of 1 April 2026, providers commonly expect the NZBN and the IRD number before you apply, so set these up first. Verify the requirement with the provider.

Prepare documents and verify identity

Gather identity for directors, owners who hold 25 percent or more, and account signatories, plus proof of the business address. Banks and fintechs run checks under the Anti Money Laundering and Countering Financing of Terrorism Act, which New Zealand applies strictly. As of 1 April 2026, fintech onboarding is usually online, while a major bank may ask a director to verify identity in person. Confirm the current document list with the provider.
