New Zealand Companies Office — what the register actually returns

Every company incorporated in New Zealand receives a permanent company number at registration under the Companies Act 1993. The identifier stays fixed for the life of the entity. A later name change does not affect it. Moving the registered office does not either. Compliance teams tend to treat that number as the real key, because filings and court documents frequently cite it rather than the company name.

The register sits with the Companies Office inside the Ministry of Business, Innovation and Employment. Alongside it runs the New Zealand Business Number system. That scheme issues a separate 13‑digit NZBN used across government datasets. Registry responses often contain both numbers. A typical payload exposes fields such as companyNumber, nzbn, companyStatus, incorporationDate, and the registered office address.

Source data from the Companies Office also carries a jurisdiction_data object. That section preserves the registry’s own field names instead of mapping them into an interpreted schema. Compliance checks often land here. Fields frequently include ultimateHoldingCompanyNumber, a list of historical names, and the date of the latest annual return. The values come straight from the underlying record. No derived interpretation sits on top.

Director information is public under the Companies Act 1993. Each director appears with an appointment date and a service address. A residential address requirement arrived in 2015, though the public register normally exposes only the service address. The residential one stays off the public extract. When retrieved programmatically, officer records usually show the director’s name, the appointment date, and the service address recorded for service of documents.

That address is not just contact detail. It has legal weight. New Zealand law treats both the registered office and a director’s service address as valid locations for serving statutory notice. The distinction surfaces during enforcement actions and litigation where service must be proven. Extracts from the Companies Office therefore carry evidentiary value similar to a company snapshot issued by Companies House in the United Kingdom.

Share ownership appears through parcels recorded in the company’s shareholder register. Companies maintain that register internally, then submit shareholder details with the annual return. The public record therefore lists shareholder names together with the number and class of shares held. The trail ends at legal ownership. If a shareholder is itself a company, the registry records that entity and stops there.

This gap matters during AML or sanctions analysis. New Zealand does not yet operate a public beneficial ownership register comparable to the UK PSC regime under Part 21A of the Companies Act 2006. The Ministry of Business, Innovation and Employment has consulted on a disclosure framework for beneficial owners. Draft policy exists. A public register has not emerged. For now the Companies Office dataset reflects legal shareholding only.

Financial reporting sits partly outside the core company profile. The Financial Markets Conduct Act 2013 requires certain large companies and FMC reporting entities to lodge audited financial statements with the Companies Office. Smaller private companies often submit nothing beyond the annual return. Expecting a full set of accounts for every company leads nowhere. The registry publishes only what statute requires.

Access through OpenRegistry works through MCP tool calls rather than a scraped web interface. The tools mirror the actions someone would perform directly on the registry site.

A simple search call looks like this:

search_companies({
  "jurisdiction": "NZ",
  "query": "Xero Limited"
})

The response returns candidate entities together with their company numbers and current status. Once the identifier is known, the full company profile can be retrieved.

get_company_profile({
  "jurisdiction": "NZ",
  "company_number": "1830488"
})

Director records appear through a separate call:

get_officers({
  "jurisdiction": "NZ",
  "company_number": "1830488"
})

Filings can then be enumerated with list_filings. Annual returns appear there. Incorporation documents often do as well. Other lodged records may show up depending on what the registry publishes. Some filings include downloadable documents. Those can be retrieved with fetch_document.

Access limits still follow the Companies Office rules. When a document sits behind the registry paywall, the API reports that restriction rather than bypassing it. The result mirrors what the registry itself exposes.

The usual compliance workflow is straightforward. Start with a company search. Confirm the statutory record of incorporation and the current status. Check the registered office. Review the directors authorised to bind the company. Those details indicate who may sign contracts and where formal notice can be served. Shareholder records then provide the first step for tracing ownership when sanctions or AML analysis requires a deeper walk up the chain.

Each request queries the live register rather than a cached dataset. A director resignation filed today appears once processed by the Companies Office. The same applies to a registered office change submitted tomorrow.

OpenRegistry exposes the New Zealand register through the same MCP interface used for the other supported jurisdictions. Documentation for the endpoint sits at https://openregistry.sophymarine.com.
