New Zealand introduces new eInvoicing and payment time rules for government suppliers
The New Zealand Government has announced new updates to its Government Procurement Rules, extending eInvoicing and payment time requirements to suppliers that work with government agencies.
These changes, announced on 10 October 2025, are designed to speed up payments to small subcontractors and encourage more large businesses to adopt eInvoicing.
The new rules take effect from 1 December 2025, with eInvoicing becoming mandatory for large suppliers from 1 January 2027.
What was announced?
The new Government Procurement Rules introduces two key updates:
- Faster payments for subcontractors: From 1 December 2025, suppliers working on government contracts must pay their subcontractors on terms no less favourable than those they receive from the government.
- Mandatory eInvoicing for large suppliers: From 1 January 2027, large suppliers (those with annual revenue over NZD $33 million) will need to send eInvoices when billing government agencies.
In short, these changes are designed to improve cashflow across supply chains and build on the government’s commitment to support fairer payment practices for suppliers and their subcontractors.
What this means for government suppliers
From December 2025, suppliers to government will need to:
- Pass on fair payment terms to subcontractors: From 1 December 2025, if your organisation is paid within 5 or 10 days by a government agency, you will need to pay your subcontractors on the same terms.
- Move away from emailed PDFs: Businesses trading with government agencies will increasingly be required to send eInvoices instead of emailed PDFs, and eInvoicing requirements will progressively be included in contracts.
- Get ready for eInvoicing: From 1 January 2026, large suppliers will be required to send eInvoices, but early preparation is encouraged.
While mandatory eInvoicing only applies to large suppliers, it signals that wider adoption and future mandates across other businesses may be on the horizon. This makes now the ideal time to prepare.
How these changes differ from earlier announcements
These new supplier requirements build on the changes announced in November 2024, which focused mainly on government agencies. Under those rules, agencies must pay 95% of their invoices within 10 business days by 1 January 2026, and have eInvoicing send and receive capability if they handle more than 2,000 invoices a year.
The latest update extends similar expectations to large government suppliers, supporting consistency and faster payment across the supply chain.
