The New Zealand Companies Register records companies, while the NZBN identifies a wider range of businesses. The Companies Office operates the corporate register within the Ministry of Business, Innovation and Employment. The two identifiers should be linked in a due diligence file without treating them as interchangeable.
A business name printed on packaging can belong to a registered company, a sole trader or another organisation. Search the proposed contracting party before relying on the brand. If the available NZBN record describes a different business type, choose the relevant source instead of forcing the result into a company profile.
Start with the company number
Obtain the exact legal name and company number from the customer’s incorporation information or existing official record. Search the Companies Register with the number where possible, and use name searching to resolve missing information. Record the entity type as well as its identifier.
For a name search, compare the registered name, status, address and available history with the customer’s documents. Similar words can return several entities, including companies that were removed from the register. A familiar brand is insufficient to choose between them. Keep the selection reason in your review note.
The New Zealand Business Number is a 13-digit business identifier. It can help connect the register entry with invoices, procurement systems and public business information. Confirm that the NZBN and company record concern the same legal person; a tax number or a group company’s NZBN should not replace the contracting company’s identity.
Distinguish local and overseas companies
A New Zealand incorporated company has a local corporate record. An overseas company registered in New Zealand remains incorporated under the law of its home jurisdiction. Its local entry describes the registration of that foreign legal person rather than a newly incorporated New Zealand subsidiary.
If the counterparty is an overseas company, collect the home country, original corporate number and the local registration details. Obtain a home-registry record for its formation and current status. A separate New Zealand subsidiary should have its own local corporate number and should be checked as a separate legal person.
- Local subsidiary: identify the New Zealand company and then trace its foreign corporate shareholder where relevant.
- Overseas company: connect the New Zealand registration to the same entity’s home-jurisdiction record.
- Trading branch or brand: establish the legal entity operating it before selecting documents or assigning ownership.
Read the current register entry
The Companies Office’s register can show registered particulars, directors, shareholders and filed documents. Compare these fields against the application, contract and supporting papers. Preserve the names and dates exactly as shown so later reviewers can distinguish a mismatch from an abbreviation or transliteration.
Registered office, address for service and trading premises have different purposes. A professional service provider’s address may be the registered office while the company operates elsewhere. Ask for an explanation where needed, and evaluate the operating location separately if the transaction depends on the delivery of goods or services.
A company’s registered status does not establish that it is profitable, licensed for a regulated activity or free of disputes. Keep those questions outside the identity conclusion. If the register records a removal, liquidation-related entry or restoration, inspect the associated filing history and document the position relevant to your transaction date.
Use filings to explain changes
A current entry is the starting point; a filing provides context for a particular change. Select incorporation documents, name changes, director notifications or other available filings when they answer an unresolved issue. Buying or downloading every document can obscure the evidence that actually resolves the discrepancy.
For example, a new director may appear in the register while an older bank form names a former director. Check the relevant filing and dates, then obtain current signing-authority evidence. Registration of a person as director supports their role but does not by itself prove that every instruction they give is authorised.
Keep the filing date separate from the date an event took effect. Registry material can be lodged after the underlying event. If your decision relies on who held an office on an earlier date, seek the document that addresses that period rather than using only today’s view.
Follow registered shareholdings
Shareholder information helps identify the immediate ownership layer. An individual shareholder may still act for another person, and a corporate shareholder requires its own company search. Write the ownership chain with exact legal names, identifiers and the record supporting each link.
Use any available share-class and holding information carefully. Economic rights and voting rights can differ, and ownership can be split across several connected entities. Where the public register does not answer the ultimate-control question, request the company’s ownership chart, share records and explanations of control arrangements.
Do not equate the director list with beneficial ownership. Directors manage or oversee the company, while shareholders hold registered interests. Your conclusion should state which layer is evidenced by the register and which layer remains supported by declarations or additional documents.
Check whether accounts should be available
The Companies Office publishes guidance on financial reporting and filing. Requirements depend on factors such as the entity’s type, size and overseas relationships. A normal company registration should not lead you to assume that audited financial statements must be available publicly for every company.
If accounts are available, record the reporting period, filing date and whether an auditor’s report accompanies them. If no accounts are located, first determine whether the entity had a filing obligation and whether the search covered the correct period. Absence of a public document is not a financial health assessment.
For credit or investment decisions, request the specific financial information your policy needs. Public registry documents can support that review, but they do not replace a current cash-flow assessment, debt information or evidence of operating performance supplied through appropriate channels.
Preserve and order the evidence
Save the register record, the selected filings and the retrieval details together. Your review should identify the company number, NZBN where matched, source and remaining limitations. Keep translations or summaries alongside the original documents rather than replacing the originals.
Request New Zealand records through the international company registry search, specifying the company number, legal name, local or overseas status and documents required. Access and feasibility are confirmed for the request. Price and expected turnaround are confirmed when the order is accepted.
Does your file identify the New Zealand legal person, or only the business name your customer uses?
