Past Due Invoice Letter Template for New Zealand

When customers or clients fail to pay invoices on time, you need a formal way to demand payment while maintaining professional relationships. A past due invoice letter serves as your official notice under New Zealand law, creating a documented trail of your collection efforts while complying with local commercial regulations.

When do you need this document?

You'll need a past due invoice letter when payment deadlines specified in your original invoice or contract have passed. This typically occurs 30 days after the original due date, though your specific payment terms may vary. The letter is essential when moving from informal reminders to formal debt collection processes. You should send this notice before engaging collection agencies or pursuing legal action, as it demonstrates good faith efforts to resolve the matter directly. It's also required when you need to establish a clear timeline of collection attempts for potential court proceedings.

Key legal considerations

Your past due invoice letter must accurately reflect the original debt amount, including any agreed interest or late fees outlined in your initial contract. Under the Fair Trading Act 1986, you cannot use misleading or deceptive practices in debt collection, meaning all claims about amounts owed, interest rates, or consequences must be truthful. The letter should reference the original invoice number, date, and payment terms to establish the legal basis for your demand. You must also provide reasonable payment options and timelines, typically allowing 7-14 days for response. If your business charges GST, ensure the outstanding amount correctly reflects GST obligations under the Goods and Services Tax Act 1985.

Legal requirements in New Zealand

New Zealand's Contract and Commercial Law Act 2017 governs the enforcement of commercial payment obligations, requiring that debt collection letters clearly state the amount owed and provide reasonable opportunity for payment. Your letter must include complete contact information for your business and specify acceptable payment methods. Under the Credit Contracts and Consumer Finance Act 2003, if dealing with consumer credit, additional disclosure requirements may apply. The Limitation Act 2010 sets a six-year limit for pursuing contract-based debt claims, making timely collection efforts crucial. Your letter should maintain a professional tone without threats or harassment, as the Fair Trading Act 1986 prohibits unconscionable conduct in debt collection. Keep detailed records of all correspondence, as these may be required if legal proceedings become necessary.
