NZBN bulk data
Apply for bulk data access to download files containing business information for NZBN registered businesses. Files are updated monthly.
What's in our bulk data files
Our bulk data files contain public NZBN information for all companies, public sector entities (including central government agencies and schools as well as local government). These types of business have been automatically allocated NZBNs.
The files also contain public business information for all sole traders (self-employed), partnerships and trusts that have applied for an NZBN.
NZBN information for registered companies is available in both JSON and CSV formats. NZBN information for other entity types (public sector entities, sole traders, partnerships and trusts) are currently available in JSON formats only.
Data for each business
Only information that's available to the public is included, for example the addresses each business records on the public register. If a business has chosen to keep some data private, that information is not displayed on the public register nor will it be available via our bulk data files.
