Privacy Act and Fair Trading Act in NZ Debt Collection — What Creditors Can and Can't Do
Holding a Disputes Tribunal order gives you the legal right to collect what you're owed. It does not give you unlimited freedom in how you go about it. Two statutes set the boundaries: the Privacy Act 2020 (overseen by the Office of the Privacy Commissioner) and the Fair Trading Act 1986 (enforced by the Commerce Commission). Cross either line and you risk a complaint, regulatory enforcement, or — in serious cases — becoming the one facing legal consequences.
This applies equally whether you're collecting the debt yourself or have handed it to a debt collection agency. You remain responsible for how your debt is pursued.
What the Privacy Act 2020 Prohibits
The Privacy Act's Information Privacy Principles (IPPs) govern how you can collect, store, use, and share personal information about the debtor.
No pretexting or deception. You cannot use a false identity, fake reason, or misrepresentation to obtain a debtor's private information — their home address, bank details, employer, or phone number. Calling a debtor's workplace and pretending to be a friend to get their home address is a breach. So is creating a fake social media account to gather information.
No unauthorised database access. Private creditors cannot access protected government databases (such as IRD records, MSD benefit information, or police records) without lawful authority. Attempting unauthorised access, or asking someone with access to look up information for you without authority, is unlawful.
No disclosure to third parties. You cannot tell the debtor's family members, employer, neighbours, or social media connections about the debt to pressure them into paying. Posting about the debt on social media (even without naming the debtor, if they're identifiable) crosses the line. Sending a letter about the debt to the debtor's workplace addressed to "the accounts department" when the debtor is an employee, not the business, is a disclosure to a third party.
Lawful tracing is permitted. You can search public registers — the Companies Office Register (free), the Personal Property Securities Register (NZ$2–$3 per search), and the LINZ Title Register (about NZ$6 per record). You can also submit a Confidential Address Request Form to the Ministry of Justice, which will use the address to serve enforcement documents without revealing it to you. These channels exist specifically for creditors in your position.
What the Fair Trading Act 1986 Prohibits
The Fair Trading Act 1986 applies to debt collection generally and prohibits misleading or deceptive conduct and harassment or coercion. The Credit Contracts and Consumer Finance Act 2003 adds responsibilities where the debt arises from a credit contract.
No fake court documents. You cannot send letters designed to look like official court notices, ministry correspondence, or bailiff warnings when they're not. Even stylistic mimicry — using similar fonts, layouts, or government-style headers — risks a Fair Trading Act complaint.
No misrepresentation of authority. You cannot claim or imply you have powers you don't have. Telling a debtor "I'll have your wages garnished next week" when you haven't filed an attachment order application is misleading. Threatening consequences you can't deliver (arrest, criminal prosecution, credit blacklisting) is prohibited.
No harassment or coercion. Repeated phone calls at unreasonable hours, threatening language, visiting the debtor's home to intimidate, or contacting them at work after being asked not to — all of these can constitute harassment.
No unauthorised charges. You cannot add collection fees, administration charges, or "late payment penalties" to the judgment debt unless the original order or a subsequent court order authorises them. Recoverable costs include official court filing fees and up to NZ$69 in allowable service expenses; the Ministry of Justice limits how often a new-address filing fee can be added to the debt.
Practical Boundaries for Self-Help Creditors
If you're enforcing a Disputes Tribunal order yourself — without a debt collection agency or lawyer — the safe path is straightforward:
Trace the debtor using public registers and official court channels only. The Companies Office, PPSR, LINZ, and the Ministry of Justice Confidential Address Request are all legitimate.
Communicate in writing. Written pre-enforcement demands (email or letter) create a paper trail and avoid the ambiguity of verbal exchanges. State the exact balance owing, direct payment details, and a reasonable deadline. Don't mimic court documents.
File through the court system. Attachment orders, warrants to seize, garnishee orders — these are the enforcement tools the District Court Act 2016 provides. They carry legal authority. Informal pressure tactics don't, and they create risk.
Stop all enforcement if the debtor enters insolvency. If you receive formal notice that the debtor has entered bankruptcy or the No Asset Procedure under the Insolvency Act 2006, you must cease enforcement immediately. Continuing is a breach.

When a Debtor Files a Privacy Complaint
If the debtor believes you've breached the Privacy Act, they can complain to the Office of the Privacy Commissioner. After the Commissioner has investigated and closed the complaint (or tried to settle it), the complainant may be able to bring a claim in the Human Rights Review Tribunal; in exceptional circumstances, the Commissioner may refer the case to the Director of Human Rights Proceedings. The Tribunal can award damages if it finds an interference with privacy, including for humiliation, loss of dignity, or injury to feelings.
This isn't hypothetical. Creditors who have publicly shamed debtors on social media, disclosed debt information to employers, or used deception to obtain personal details have faced formal findings.
The enforcement guide includes a creditor compliance checklist that maps each enforcement step against the Privacy Act and Fair Trading Act boundaries — so you can pursue what you're owed without creating a liability of your own.
