Complaint Letter (New Zealand)

A Complaint Letter in New Zealand formally puts the other party on notice of a concern or claim and states what is required to resolve it, supporting later action under the Companies Act 1993.

The Consumer Guarantees Act 1993 (CGA) is the primary consumer protection statute for goods and services in New Zealand. The CGA implies mandatory consumer guarantees into every supply of goods or services to a consumer — defined as a person who acquires goods or services of a kind ordinarily acquired for personal, domestic, or household use. The key guarantees for goods include: acceptable quality (s 6) — goods must be safe, durable, free from defects, fit for their common purpose, and acceptable in appearance and finish; fitness for a disclosed purpose (s 8); and correspondence with description (s 9). For services, the guarantees include reasonable care and skill (s 28), fitness for a disclosed purpose (s 29), completion within a reasonable time (s 30), and a reasonable price where no price is agreed (s 31). These guarantees cannot be excluded by any contract term in a consumer transaction.

The Fair Trading Act 1986 (FTA) complements the CGA by prohibiting misleading or deceptive conduct in trade (s 9) and specific forms of false representations (ss 10–16). The Commerce Commission enforces the FTA with powers to impose pecuniary penalties, seek injunctions, and require corrective advertising. Consumers may also claim compensation under section 43 of the FTA.

For financial services — including banking, credit, insurance, KiwiSaver, and investments — the Banking Ombudsman Scheme and the Insurance and Financial Services Ombudsman (IFSO) provide free external dispute resolution. Consumers must first complain directly to the financial firm before escalating to the relevant ombudsman.

For smaller monetary claims, the Disputes Tribunal (formerly the Small Claims Tribunal) provides an accessible, informal, and low-cost forum for resolving civil disputes up to NZD $30,000. The Disputes Tribunal is designed to be used by individuals without legal representation. Most regulators and ombudsmen require evidence that a formal complaint was made directly to the business before accepting an escalated complaint, making this formal complaint letter a critical first step.

A New Zealand Complaint Letter is needed whenever a consumer or business has a grievance with a supplier, service provider, or government agency that has not been resolved through informal contact — and before escalating to a regulator, ombudsman, or the Disputes Tribunal.

The most common use is complaints about defective goods — for example, a product that fails shortly after purchase, a household appliance that stops working, electronics that do not function as described, or clothing that falls apart after normal use. These complaints rely on the consumer guarantee of acceptable quality under section 6 of the Consumer Guarantees Act 1993. Where a major failure has occurred, the consumer is entitled to reject the goods and choose a full refund or replacement under section 18 of the CGA.

Service complaints are equally common in New Zealand — a tradesperson who has performed defective or incomplete work, a professional services firm that has provided services below the required standard of care, a telecommunications provider that has failed to deliver the advertised service, or accommodation that does not match its description. These complaints rely on the service guarantees in sections 28–31 of the Consumer Guarantees Act 1993.

Complaints about misleading or deceptive conduct — where a business has misrepresented the features or price of a product, engaged in bait advertising, made false claims about their qualifications or accreditations, or used conduct likely to mislead consumers — rely on section 9 of the Fair Trading Act 1986.

Financial services complaints in New Zealand include disputed bank charges, insurance claim denials, KiwiSaver fund disputes, and credit product misrepresentation. These are addressed first through the financial firm's internal complaints process and then escalated to the Banking Ombudsman or IFSO if unresolved.

Privacy complaints about misuse of personal information — for example, where a business has disclosed personal information to third parties without consent, failed to secure personal data, or refused to provide access to information held — are addressed first to the organisation concerned and then to the Office of the Privacy Commissioner under the Privacy Act 2020 if unresolved.

An effective New Zealand Complaint Letter must contain several key elements to be compelling, legally grounded, and useful as evidence in any subsequent escalation or proceedings.

Identification of the parties: your full name, address, phone, and email; the full name of the business or agency (for companies, as registered on the New Zealand Companies Register), addressed to the appropriate complaints manager or department; and any relevant account, order, contract, or policy number.

Date and reference information: the date of the letter and the date of the purchase or incident. The date starts the response period and demonstrates when the formal complaint was made.

Legal basis: the specific CGA provision or FTA section relied on — for example, 'the goods fail to comply with the consumer guarantee of acceptable quality under section 6 of the Consumer Guarantees Act 1993' or 'your conduct constitutes misleading or deceptive conduct in breach of section 9 of the Fair Trading Act 1986'. Citing the specific provision demonstrates awareness of New Zealand consumer law.

Factual description: a clear, chronological account of what occurred — the purchase, the failure, communications with staff, and the impact on you. Include dates, names of staff spoken with, and specific details of what went wrong.

Prior resolution attempts: evidence that you have already attempted to resolve the matter informally. This demonstrates good faith and is required by most regulators and ombudsmen before accepting an escalated complaint.

Specific remedy: a precisely stated desired outcome — a full refund of a stated amount in NZD, repair of specific defects by a specific date, replacement with a specified product, or compensation for a stated loss. Reference the applicable CGA remedy (ss 18–19 for goods, ss 32–33 for services).

Supporting documents: a list of all evidence enclosed — receipts, photographs, repair tickets, correspondence.

Response deadline and escalation warning: a clear deadline of 14–21 days and a warning that you will escalate to the Commerce Commission, the Disputes Tribunal (for claims up to NZD $30,000), the Banking Ombudsman, the IFSO, or the Office of the Privacy Commissioner if the matter is not resolved.
