Dear [Debtor name],
This letter is a formal demand for payment of the overdue amount on invoice [invoice number], dated [invoice date], for the sum of $0.00. This invoice was due for payment on [original due date] and remains unpaid.
Despite the due date having passed, payment has not been received. I am now requesting that the full outstanding balance of $0.00 be paid in full within 7 days of the date of this letter — that is, by 25 August 2026.
If payment is not received by 25 August 2026, or you do not contact me to arrange settlement, I may file a claim with the Disputes Tribunal to recover the amount owed, plus any filing fee.
If you have already made this payment, please disregard this notice and send me the payment details so I can update my records. If you dispute this invoice or are facing difficulty paying, please contact me as soon as possible so we can discuss a resolution.
I would prefer to resolve this matter directly and without further escalation.
Yours sincerely,
[Your business name]

This is an educational template, not legal advice. A letter of demand is a formal request for payment before escalation — it is not a court document. Keep the tone firm but factual: under the Fair Trading Act and debt-collection conduct rules you must not threaten action you cannot lawfully take, mislead the debtor, or harass them.
A letter of demand is the formal step you take when an invoice is well past due and ordinary reminders have not worked. It is a firm but polite request for payment that puts the debtor on notice you intend to escalate. Think of this demand letter for payment as the line between casual chasing and formal recovery — it is not a court document, and it has no legal force on its own, but it shows you are serious.
A good final notice for an unpaid invoice contains the same core facts every time: who you are, who owes the money, the invoice number(s) and date, the exact amount outstanding, the original due date, a clear new deadline, and a single genuine next step if it goes unpaid. The generator above assembles all of that into a clean outstanding payment letter template you can send straight away.
The most common mistake in a debt collection letter template is overreaching. Under the Fair Trading Act and New Zealand's debt-collection conduct rules, you must not mislead the debtor, threaten action you cannot lawfully take, pretend you have legal powers you do not have, or harass them. State the debt, the deadline, and a real next step — nothing more. That is what makes this a safe final demand letter template NZ tradies can rely on.
If your before legal action letter NZ still does not get a response, the usual next step is the Disputes Tribunal, which hears money claims up to $30,000 (or up to $60,000 if both parties agree in writing). It is low-cost and informal, and you do not need a lawyer. Before you get there, work through our guide on how to collect unpaid invoices in NZ, and if the client has gone quiet, read what to do when a client refuses to pay.
If your payment terms allow it, you can add late-payment interest to the amount you demand — work out the figure with our late payment interest calculator. For the bigger picture on what you can lawfully recover, see our guide to your legal rights when chasing unpaid invoices. Want a starting point to adapt by hand? Our debt recovery letter sample walks through the wording in full. This page is an educational template, not legal advice.
A letter of demand should clearly identify your business, the debtor, the invoice number(s) and date, the exact amount owed and the original due date. State a firm payment deadline (commonly 7 days), explain what will happen if the debt is not paid, and keep the tone firm but professional. The generator above builds all of this for you.
No. A letter of demand is a formal request for payment before escalation — it is not a court order or a court document. It puts the debtor on notice that you intend to take the matter further, but it has no legal force on its own. The next formal step is usually the Disputes Tribunal or the District Court.
The Disputes Tribunal can hear claims for money owed up to $30,000. If both parties agree in writing, that limit can rise to $60,000. It is a low-cost, informal forum — you do not need a lawyer — which makes it a common next step after a demand letter for unpaid invoices.
Under the Fair Trading Act and debt-collection conduct rules you must not mislead the debtor, threaten action you cannot lawfully take, imply you have legal powers you do not have, or harass them with excessive contact. Keep your final demand letter factual: state the debt, the deadline and a genuine next step.
Seven days is a common and reasonable deadline for a final demand letter once an invoice is already overdue. The generator defaults to 7 days but you can set any period that is fair given your payment terms and the amount outstanding.
