A clear, firm letter is often all it takes to get an overdue invoice paid — and this debt recovery letter sample gives you a copy-paste template built for New Zealand trade businesses. A well-written letter of demand shows your customer you're serious, creates a paper trail, and is usually the last step before formal legal debt recovery. Below you'll find the full template, a breakdown of what to include, and guidance on what happens next.

What a letter of demand is for

A letter of demand is a formal written request for payment of a debt you're owed. It's not a court document, but it carries weight: it makes clear that you've moved past friendly reminders and are prepared to escalate. For most tradies, sending one is the turning point in the recovery of debt — many customers who ignored casual nudges pay up once a formal demand lands.

It also matters legally. If your matter later reaches the Disputes Tribunal, a copy of your demand shows you gave the debtor a fair chance to pay before filing. Think of it as the bridge between informal follow-up and debt recovery proceedings.

What to include in a debt recovery letter

A good demand is short, factual, and unemotional. Stick to the facts and a clear deadline. Here are the essential elements:

Element	Why it matters
Your business name and contact details	So the debtor knows exactly who is owed and how to pay
Debtor's name and address	Identifies the correct legal party
Invoice number(s) and date(s)	Ties the demand to specific work
Amount owed	The exact figure, including any agreed interest
Original due date	Shows the debt is overdue
A clear payment deadline	Usually 7–14 days from the letter
Payment method	Makes it easy to pay
Consequences of non-payment	States that legal debt recovery may follow
Date of the letter	Starts the clock and supports any later claim

Keep the tone professional, not threatening. Under the Fair Trading Act 1986, you must not mislead or harass a debtor — so no inflated figures, no fake deadlines, and no aggressive language.

RE: FINAL DEMAND FOR PAYMENT — Invoice [#####]

Dear [Name],

Our records show that invoice [#####], dated [date] for the sum of
$[amount], remains unpaid. This invoice was due for payment on
[due date] and is now [X] days overdue.

Despite previous reminders, we have not received payment. This letter
is a formal demand for the full amount of $[amount].

Please pay the outstanding balance in full by [deadline — e.g. 14 days
from the date of this letter] using the following details:

   [Bank account / payment instructions]

If payment is not received by [deadline], we may commence debt
recovery proceedings without further notice. This could include filing
a claim with the Disputes Tribunal and seeking recovery of costs.

If you believe this amount is incorrect, or you wish to discuss a
payment arrangement, please contact us on [phone] or [email] before
the deadline above.

Yours sincerely,

[Your Name]
[Your Business Name]

When a final demand precedes legal action

A letter of demand is usually the final step before you file. If the deadline passes and the debt is genuinely owed and undisputed, your main route is the Disputes Tribunal, which hears claims up to $60,000 — no lawyer required, low cost, and relatively quick. Larger debts go to the District Court.

Before you escalate, run this quick checklist:

Is the debt undisputed? If the customer genuinely contests the work, the Tribunal will weigh both sides.
Have you given a fair deadline and a chance to respond?
Is the debt within the time limit? (More on that below.)
Do you have your paperwork — invoice, contract or quote, and the demand letter?

If you've ticked those boxes, you're ready for legal debt recovery. Our guide to small business debt recovery NZ covers filing in more detail.

Mind the six-year limit

Under the Limitation Act 2010, you generally have six years from the date a debt falls due to bring a claim. A letter of demand doesn't pause that clock — only payment, a written acknowledgement of the debt, or filing a claim affects it. So don't sit on an old invoice; send your demand and follow through while the debt is still recoverable.

Frequently asked questions

Can I use this debt recovery letter sample for any NZ business?

Yes. The template suits any New Zealand trade or small business chasing an unpaid invoice. Adjust the amounts, dates, and deadline to fit your situation, and keep the tone factual.

Does a letter of demand start legal debt recovery proceedings?

No. A letter of demand is the step before proceedings. It gives the debtor a final chance to pay. If they don't, you can then file a claim — usually with the Disputes Tribunal for debts up to $60,000.

What's the difference between recovery of debt and legal debt recovery?

Recovery of debt covers the whole process — reminders, calls, and letters. Legal debt recovery refers specifically to court or Tribunal action when informal steps and a final demand haven't worked.

How long should I give the debtor to pay?

Most letters give 7–14 days. That's seen as fair while still keeping pressure on. Make sure the deadline is realistic and don't threaten action you're not prepared to take.
