About this API
The NZBN (New Zealand Business Number) is the unique identifier for every business in New Zealand. MBIE (Ministry of Business, Innovation and Employment) maintains a register of business data by NZBN — the equivalent of a combined KRS and CEIDG.
Frequently asked questions
Do I need an API key?
Yes — it requires a free API key (register on the MBIE developer portal).
What data does this API return?
A New Zealand business's data by NZBN — name, status, address, entity type and contact details.
Can this API be called directly from a browser?
Not easily — key/registration-based authentication requires a server-side call and is not suitable for frontend code visible to visitors (which is why there is no live "Try it" button here).
Who runs this API?
MBIE (New Zealand's Ministry of Business, Innovation and Employment). Documentation: api.business.govt.nz.
