Supplier Invoice Template for New Zealand

A Supplier Invoice is a fundamental commercial document that formally requests payment from your customers for goods or services you have delivered. Under New Zealand law, this document must comply with strict requirements outlined in the Goods and Services Tax Act 1985 and other relevant legislation to ensure legal validity and tax compliance.

When do you need this document?

You need a Supplier Invoice whenever you complete a sale or service delivery to a business customer in New Zealand. This includes situations where you've delivered physical goods, completed contracted services, provided consulting work, or fulfilled any commercial arrangement requiring payment. The invoice serves as your formal payment request and creates a legal record of the transaction that protects both parties' interests while ensuring compliance with New Zealand's tax obligations.

Key legal considerations

Your Supplier Invoice must include several mandatory elements to comply with New Zealand law. Under the GST Act 1985, if you're GST-registered, you must include your GST number, the GST amount charged, and clearly identify whether GST is included in your pricing. The Fair Trading Act 1986 requires that all product or service descriptions are accurate and not misleading, while pricing information must be clear and unambiguous. You should also include detailed payment terms, including due dates and acceptable payment methods, as these become part of the contractual agreement. The Tax Administration Act 1994 mandates specific record-keeping requirements, so ensure your invoice numbering system is sequential and traceable.

Legal requirements in New Zealand

New Zealand's regulatory framework imposes specific formatting and content requirements for business invoices. The Companies Act 1993 requires that your business name and address appear prominently on all commercial documents. If you're GST-registered, the Goods and Services Tax Act 1985 mandates that invoices over $50 must include your GST number, the customer's details, a description of goods or services, the GST-inclusive amount or GST-exclusive amount plus GST separately, and the date of supply. The Contract and Commercial Law Act 2017 validates electronic invoices provided they meet the same content requirements as paper versions. Additionally, the Financial Transactions Reporting Act 1996 may apply to certain high-value transactions, requiring additional documentation and reporting. All invoices must be retained for seven years under tax legislation, and the information must be readily accessible for audit purposes. Ensure your invoice clearly states payment terms, as these become legally binding once the customer accepts your goods or services.
