Quick read

  • The Defamation Act 1992 matters whenever your business publishes statements that could harm someone’s reputation, or when your business is the target of a damaging public...
  • In practice, this reaches much further than newspapers.

Likely relevant if

  • Publishers, news outlets and online media businesses
  • Marketing agencies, PR firms and brand managers
  • Businesses that post reviews, warnings or allegations about competitors, suppliers or customers

Check first

  • Do not assume a harmful statement is safe to publish just because it is about a business issue or customer complaint.
  • If relying on truth, be able to prove the imputations are true or not materially different from the truth.
  • If relying on honest opinion, make sure the opinion is genuine and that publication of another person’s opinion meets the Act’s conditions.

What the Act does

The Defamation Act 1992 is the main New Zealand statute dealing with defamation and some related malicious falsehood claims. It sets out when claims can be brought, the main defences, available remedies and a number of procedural rules for court proceedings.

For business owners, the Act is most relevant when you publish statements that could damage a person’s or organisation’s reputation. That can include allegations of fraud, poor workmanship, unsafe conduct, dishonesty, harassment, non-payment, regulatory breaches or other misconduct.

It also matters if your business is deciding whether to respond to a harmful publication made about you. A bad statement can create both reputational damage and commercial loss, especially if customers, suppliers, members or investors see it.

Practical sense check

  • Treat website posts, social media, newsletters, press releases and mass emails as publications that can create risk
  • Be especially careful with statements that accuse someone of unlawful, dishonest or unethical conduct
  • Remember that the Act also deals with malicious falsehoods likely to cause pecuniary loss
  • If your business is harmed by a publication, consider both reputational harm and measurable financial impact

Who is in and common trigger points

The Act applies broadly. It binds the Crown and applies to proceedings commenced after it came into force. In everyday business terms, it can affect media businesses, employers, associations, agencies, distributors and ordinary trading businesses that publish statements to customers, members, investors or the public.

Common trigger points include publishing a customer warning, naming a former employee in a public statement, posting allegations about a competitor, circulating complaint findings to members, issuing a press release after an internal investigation, or republishing third-party material without checking it.

A business can also face risk by forwarding or endorsing someone else’s accusation. Repeating a statement can still create exposure if the statement harms reputation and no defence applies.

Key points

  • A director posts online that a rival business is running a scam
  • A retailer emails customers saying a supplier sold unsafe goods before the facts are settled
  • An employer tells industry contacts that a former worker was dismissed for theft
  • An association publishes disciplinary findings about a member
  • A media or PR business republishes allegations from another source
  • A distributor or processor circulates material without knowing it contains defamatory content

When a business claim or risk arises

The Act says defamation is actionable without proof of special damage. In practical terms, a claimant does not need to allege or prove special damage just to bring defamation proceedings.

For malicious falsehood claims such as slander of title, slander of goods or other malicious falsehood, special damage is also not required if the publication is likely to cause pecuniary loss to the plaintiff.

There is a special rule for body corporates. A company or other body corporate cannot succeed in defamation proceedings unless it alleges and proves that the publication has caused pecuniary loss or is likely to cause pecuniary loss. That is a key commercial filter for businesses considering a claim.

The Act also provides that a single publication constitutes one cause of action, no matter how many imputations the published matter contains.

Risk controls

  • If you are a company, identify the likely financial impact before threatening proceedings
  • Preserve the publication itself, including screenshots, dates and audience reach
  • Record whether the statement was repeated across different channels
  • Separate reputational upset from measurable business loss

Main defences businesses rely on

The Act sets out several important defences. The first is truth. A truth defence succeeds if the defendant proves the imputations were true, or not materially different from the truth. Where the claim is based on all or part of a publication, the defence can also succeed if the publication taken as a whole was in substance true, or not materially different from the truth.

The second major defence is honest opinion. This applies to matter that includes or consists of opinion. If you are the author, you must prove the opinion was genuinely yours.

If you publish someone else’s opinion, the Act applies different tests depending on whether that person was your employee or agent. The publication must not purport to be your own opinion unless the legal requirements are met.

There are also defences of innocent dissemination and consent to publication. Innocent dissemination can matter for processors, distributors and those acting only in that capacity, but only if they lacked the relevant knowledge and were not negligent.

In practice

  • Truth is about being able to prove the substance of the allegation
  • Honest opinion is not a free pass for disguised factual accusations
  • Publishing another person’s opinion needs care, especially if readers may think it is your business’s view
  • Innocent dissemination is limited and depends on lack of knowledge and lack of negligence
  • Consent can be a defence if the plaintiff agreed to the publication

Privilege and reporting protections

The Act recognises absolute privilege and qualified privilege for certain publications. Absolute privilege covers proceedings in Parliament, some related parliamentary publications, certain judicial and tribunal proceedings, and some communications for obtaining legal advice.

Qualified privilege protects specified matters and some reports listed in Schedule 1, subject to limits. For businesses, this can be relevant when reporting on court proceedings, public meetings, inquiries, company or society meetings, public registers, official notices and some government information.

But the protection is not automatic. Publication may lose protection if publication is prohibited by law or lawful order. For some Schedule 1 reports, the matter must be of public interest where published, and a defence can fail if a reasonable request for explanation or contradiction is not handled properly.

The Act also allows qualified privilege to be rebutted if the plaintiff proves the defendant was predominantly motivated by ill will or otherwise took improper advantage of the occasion of publication.

Practical sense check

  • Check whether the source is one of the protected categories before relying on privilege
  • Make sure any report is fair and accurate
  • Check whether publication is prohibited by law or court order
  • Consider whether the matter is of public interest where that requirement applies
  • Take requests for explanation or contradiction seriously

Corrections, retractions and remedies

The Act gives several ways a dispute may be resolved or narrowed. A plaintiff may seek a declaration of liability.

A person who says they were defamed in a news medium may, within 5 working days after becoming aware of the publication, request a retraction or a reasonable reply in the same medium, with substantially similar prominence and without undue delay.

If the publisher agrees to publish a retraction or reply, the Act also requires an offer to pay certain costs and expenses. These include the cost of publishing a reply where that is agreed, solicitor and client costs connected with the publication of the retraction or reply, other reasonably incurred expenses connected with the publication complained of, and compensation for direct pecuniary loss.

The court may also recommend a correction. If a defendant publishes a correction in accordance with the court’s recommendation, the plaintiff is entitled to no other relief or remedy against that defendant in those proceedings apart from the costs position set by the Act.

The Act also allows punitive damages, but only where the defendant acted in flagrant disregard of the plaintiff’s rights.

Damages, costs and litigation behaviour

The Act sets out matters that can reduce damages. Corrections, retractions, apologies and statements of explanation or rebuttal can all matter, depending on their nature, extent, form, manner and timing.

Proposed injunctions or declarations can also be relevant, as can delay for which the plaintiff was responsible.

The defendant may also prove specific instances of misconduct by the plaintiff to show the plaintiff’s reputation was generally bad in the relevant aspect. The Act further allows evidence that the plaintiff has already recovered damages, brought proceedings, or received or agreed to receive compensation for the same or substantially the same matter.

There are also cost and conduct rules worth noting. In proceedings against a news medium, the plaintiff must not specify the amount of damages in the statement of claim. If damages claimed are grossly excessive and the plaintiff recovers less, the court must award the defendant solicitor and client costs. Proceedings begun with no intention of going to trial are deemed vexatious.

Key points

  • A prompt apology may help on damages, but it should be handled carefully
  • Overstated claims can create cost consequences
  • Settlement and compensation paid elsewhere may affect later damages
  • Litigation strategy should match a genuine intention to proceed

Procedure, records and practical controls

The Act contains detailed procedural rules that matter once a dispute starts. Plaintiffs must give particulars of every statement alleged to be defamatory and untrue, and must identify the meanings alleged.

Defendants pleading truth must specify the factual statements relied on and the supporting facts and circumstances. Truth and honest opinion must be pleaded separately.

There are also notice requirements. If a plaintiff wants to allege that an opinion was not genuinely held, or that a qualified privilege publication was driven by ill will or improper advantage, notice must be served within the time set by the Act unless the court allows more time.

The Act also deals with multiple actions, consolidation, limits on later proceedings, and striking out for want of prosecution where no step has been taken for 12 months and no trial date has been fixed.

For businesses, the practical lesson is to keep disciplined records before and after publication. Good records help prove truth, show a statement was opinion, support a privilege argument, or justify a correction response.

Documents to keep in order

  • Keep source documents, interview notes, complaint records and verification steps
  • Record who drafted, reviewed and approved the publication
  • Separate factual assertions from commentary in drafts
  • Keep copies of correction requests and your response timing
  • Track where and when the material was published across channels
  • If republishing, record why you believed the source was reliable and whether privilege might apply

Common questions

Can a company sue for defamation in New Zealand?

Yes, but the Act sets a special threshold for a body corporate. Proceedings brought by a body corporate fail unless it alleges and proves that the publication has caused pecuniary loss or is likely to cause pecuniary loss to that body corporate.

If we label something as opinion, are we safe?

Not automatically. The Act recognises an honest opinion defence, but the opinion must be genuine. If you are publishing someone else’s opinion, extra conditions apply depending on whether that person is your employee or agent and whether the opinion appears to be yours.

What should we do if we publish something wrong in a news medium?

The Act includes a process for retraction or reply. A person who says they were defamed in a news medium may request a retraction or a reasonable reply within 5 working days after becoming aware of the publication. Corrections, retractions and apologies can also matter when damages are assessed.

Does repeating material from a meeting, court or public register remove the risk?

Not always, but some reports and publications may be protected by absolute or qualified privilege. The protection depends on the type of source, whether publication is prohibited, whether the report is fair and accurate, and in some cases whether the matter is of public interest and whether a reasonable request for explanation or contradiction was handled properly.
