New Zealand: The government plans to mandate e-invoicing for large businesses supplying government agencies from 1 January 2027, aiming to cut costs and improve cash flow. The initiative is expected to generate up to NZ$800 million in annual savings by streamlining invoice processing and reducing administrative work.

New Zealand’s Goods and Services Tax (GST) is highlighted as a model consumption tax, featuring a single 15% rate, minimal exemptions, and a broad base that yields a stable revenue stream. The system’s simplicity reduces compliance burdens and has been praised for its efficiency and neutrality. Key innovations include zero‑rating business‑to‑business financial services and excluding most crypto assets from GST.

New Zealand GST invoices must be issued within 27 days of the supply and retained for at least seven years. They must contain specific details such as supplier and customer information, invoice date, description, taxable amount, GST, and gross amount. Invoices below NZD 1,000 may omit customer details and detailed GST calculations, and no tax invoice is required for supplies of NZD 50 or less.

New Zealand’s Inland Revenue explains how e‑invoicing works, the benefits, and the changes to GST record‑keeping that took effect on 1 April 2023. The guidance notes that e‑invoices are exchanged via the Peppol network and that suppliers are encouraged to send them instead of PDFs.
