NZBN Business Passport trial: what it means for NZ businesses

What MBIE launched this week

On 3 November the Ministry of Business, Innovation and Employment (MBIE) began a trial of the NZBN Business Passport, RNZ reported. The passport is a digital credential. It proves a business's identity and confirms that a particular person has authority to act for the business. Its data comes from the NZBN Register, according to the NZBN trial page. MBIE calls the passport New Zealand's first government-issued digital credential. It's also the second credential accredited under the Digital Identity Services Trust Framework.

Few businesses can use the passport yet. The trial is invitation-only and limited to selected Westpac business customers. They keep the passport in the Govt.nz app wallet and will be able to link it to Westpac One for Business when that feature arrives. For now Westpac is the only organisation that accepts the passport. Phase one mainly tests how passports are issued and applied for (NZBN). Alan Carnaby, MBIE's acting head of digital business enablement, described the problem the credential is meant to fix: "Businesses are often asked to provide the same information to multiple organisations." (Biometric Update).

How the passport pairs with Westpac's bank credential

The passport works alongside a credential Westpac already issues. In September Westpac became the third organisation accredited to issue digital ID under the Trust Framework, after NEC New Zealand and the Government Digital Delivery Agency, 1News reported. A Westpac One Business customer can create a credential proving they hold a particular business bank account. They load it into the Govt.nz wallet by scanning a QR code and entering a code sent by text message, and can then share it with other organisations. Westpac's bank account credential is valid for 72 hours. Russell Jones, Westpac's chief data, digital and AI officer, told 1News the process removes the need to download bank statements and redact them by hand, which he said lowers fraud and scam risk.

Together the two credentials cover three things. The government credential proves the business's identity and who can act for it. The Westpac credential proves which bank account the business owns. A counterparty can check both without anyone emailing a PDF. Government material quoted by 1News says credentials stay encrypted on the holder's device and aren't kept in a government or company database. Phil Weir, a deputy secretary at the Digital Delivery Agency, told 1News that the Trust Framework Authority independently assessed the passport against privacy and security requirements. The passport can also be shown in person and checked with the Verify Me app (NZBN).

Why a small trial is worth watching

None of the published sources gives a participant count, trial length or end date. Most firms won't notice the passport for some time. The trial matters for a different reason. The passport is a reusable proof of business authority, and most New Zealand organisations still check business authority with certified copies, signed forms and phone calls.

The Govt.nz wallet has started slowly. In October Biometric Update reported that the wallet was live but held few credentials:

• NZTA expects the digital driver licence to be publicly available in the second half of 2027.
• The Government Digital Delivery Agency said Inland Revenue tax credentials were unlikely to arrive in 2026.
• Eight more credentials from five agencies are in development.
• The agency is targeting 4 million issued credentials by the second quarter of 2028.

Digital Identity New Zealand calls the underlying difficulty a cold start problem. Its May newsletter explains that New Zealand's system is voluntary, with no mandate. Issuers wait for relying parties (the organisations that accept credentials), relying parties wait for useful credentials, and users wait for both. A business credential with a major bank as its first acceptor gives the system a commercial use case with a clear payoff. MBIE is talking with other banks and organisations (1News) and wants to extend the passport beyond Westpac (RNZ). Trial feedback will shape decisions about wider adoption.

What it means for NZ businesses

Organisations that take on other businesses as customers or suppliers stand to gain the most. Examples include a wholesaler approving a trade account, an accounts payable team setting up a new supplier, an equipment financier checking a borrower and an accounting practice onboarding a client. Each one has to confirm the company exists, that the person signing has authority and that the bank details are real. Today those checks usually mean an email with attachments that someone checks by eye and then keys into an ERP or CRM. A credential that's verifiable and expires quickly, like Westpac's 72-hour bank account proof, gives staff a proof they can verify for themselves.

Businesses holding credentials will have to manage them like any other access right. Someone has to decide which directors or managers hold the passport, and what happens when one of them leaves. The passport takes its data from the NZBN Register and can include details that aren't publicly visible there (NZBN), so an out-of-date register entry will produce an out-of-date credential.

For now Westpac is the only acceptor and MBIE hasn't set a timeline for wider availability, so rebuilding onboarding around the passport would be premature. The sensible step is to find out where verification currently sits in your processes and systems, so a credential check can replace a manual step once more organisations accept it. That's the kind of groundwork a digital transformation plan should record before any integration work starts.

Practical next steps

• Check that your business's NZBN Register details are accurate and complete, since the passport draws its information from the register.
• If you bank with Westpac, watch for a trial invitation. Other businesses can register interest through the NZBN trial page.
• Map each onboarding process where you collect proof of identity, authority to act or bank account ownership from another business. For each one, note the system involved and who performs the check.
• Review how your accounts payable team handles supplier bank detail changes. Callback and approval controls are worth having whether or not credentials take off.
• Decide now who in your organisation would hold and manage business credentials, and add credential removal to your staff offboarding checklist.
• Follow MBIE's decision on wider adoption, and ask your bank and major trading partners whether they plan to accept the passport. If you're mapping these processes as part of a wider systems review, our digital transformation team can help you prioritise.
