The New Zealand Government backs eInvoicing
In November 2024, the New Zealand Government Procurement Rules were updated to include requirements for mandated government agencies to send and receive eInvoices by 1 January 2026. Under the rules, agencies must also pay supplier eInvoices within 5 business days.
To exchange eInvoices with government you’ll first need accounting or invoicing software that can send and/or receive eInvoices.

Sending eInvoices to government agencies relies on 2 things:
- The government agency’s New Zealand Business Number (NZBN ) – this ensures your eInvoices get to the right government agency.
- The specific invoice reference requirements for that agency.
