Prize competition rules and regulators in New Zealand
Prize competition rules in New Zealand are spread across three official bodies rather than held by one contest regulator. The Department of Internal Affairs publishes guidance on sales promotion schemes and warns that the Fair Trading Act can also apply to them. The Commerce Commission requires every condition of a competition offering gifts or prizes, including relevant time limits, to be clearly stated. The Advertising Standards Authority enforces a code that obliges advertisers to hold evidence for claims made in an advertisement. An organiser who runs an online public vote or a prize draw therefore answers to general consumer law and advertising standards alongside any contest-specific obligations, and a participant who wants to check a contest's standing should start with those three sources.
Facts last tested on 8 October 2026.
Conditions must be stated clearly and completely.
The clearest single demand on any organiser is the Commerce Commission's wording: all the conditions that apply, including any relevant time limits, must be clearly stated. Read that as a checklist for a rules page. Who may enter. What closes the contest. How winners are chosen. When and how prizes arrive. Each item is a condition, and each condition a participant could reasonably rely on is one the Commission expects to see published, not improvised later.
Time limits get their own mention in the guidance, which tells you how often they go wrong. A promotion that says entries close on a Friday but keeps accepting them over the weekend has stated a condition and broken it at the same time. An online public vote with a closing deadline has the same exposure, because the counter and the stated deadline must agree. Where the deadline slips, the change and its reason belong in the published rules.
The DIA's sales promotion fact sheet adds a wider warning: be aware of any other New Zealand legislation, such as the Fair Trading Act, that may also affect a sales promotion scheme. The practical consequence is that a condition can satisfy the Commission's transparency demand and still mislead, and misleading conduct carries its own exposure under general consumer law. Clarity is the floor, not the whole building.
What follows from this is an ordering rule for organisers: draft the conditions first, publish them where entry happens, and change them only visibly. A participant who can quote the rules back at the organiser is exactly what the guidance intends.
- A rules page should answer who may enter, what closes entry, and how winners are chosen.
- Time limits are called out separately in the Commerce Commission guidance, so treat them as a priority.
- A stated deadline that the entry system does not honour is a condition broken in public.
- The Fair Trading Act can apply to a scheme even where its conditions are transparent.
- Changes to published conditions need the same visibility as the original conditions.
Skill and chance are treated differently.
The reason regulators look at a contest at all is the line between skill and chance. A competition where the winner is decided by the entrant's own ability, such as a photography contest judged on merit, is not a gamble in the ordinary sense; the participant's effort, not luck, decides the outcome. A prize draw where the winner is pulled at random from a hat sits closer to the territory the Department of Internal Affairs regulates, which is why its sales promotion fact sheet exists at all.
An online public vote occupies its own middle ground. The entrant supplies an entry, and the audience supplies the decision, so luck plays a smaller role than in a draw but a larger one than in judged skill. The regulator's interest follows the mechanics: where a purchase is required to enter a chance-based scheme, the gambling side of the rules comes nearest, and where entry is free and the outcome rests on merit or on open voting, consumer and advertising law carry most of the weight.
This distinction matters for the licence question. The DIA's guidance exists because sales promotion schemes can drift toward gambling, and its fact sheet tells organisers to check other legislation as well. An organiser who cannot say, in one sentence, whether their contest rewards skill, open voting or chance has not finished designing it, and the rules they owe the public depend on that answer.
The honest limit here is that this page maps the distinction without ruling on any single scheme. The DIA's own material is where an organiser tests a specific design against the gambling side.
- Judged skill contests sit furthest from gambling rules because merit decides the outcome.
- Random prize draws sit closest to the territory the Department of Internal Affairs regulates.
- A public vote sits between the two, and the mechanics decide which rules reach it.
- Where entering a chance-based scheme requires a purchase, the gambling side of the framework draws nearest.
- An organiser should be able to name, in one sentence, what decides their contest's winner.
Breaches, complaints and fake contests.
What actually happens when the rules are broken depends on which layer failed. A complaint about misleading contest conditions can reach the Commerce Commission, whose published demand about clearly stated conditions defines what it expects to find. A complaint about an advertisement's claims can reach the Advertising Standards Authority, which tests them against the evidence the advertiser is required to hold. A scheme that has drifted into gambling territory belongs to the Department of Internal Affairs. Each body acts on its own ground.
Participants arrive with a second worry: the fake contest. The regulatory answer is indirect but usable. A genuine promotion has stated conditions, stated time limits, and advertising whose claims the organiser can substantiate, because three official documents demand exactly that. A promotion with no conditions, a deadline that moves, and claims nobody can back up is failing the published tests on every layer at once, and that is a reasonable basis for walking away or reporting it.
Platform rules add a layer the regulators do not cover. A social platform's own terms decide what voting behaviour is allowed, and an organiser can disqualify entries that breach those terms even where the law says nothing. The moderation step, the vote counter and the published entry rules are what an organiser can actually see and act on. That is also why a suspicious result on an online public vote is first a question about the organiser's published rules and the platform's logs, not about any external review.
For a participant, the sequence is: read the conditions, check the deadline matches the mechanics, and only then spend effort on entry. For an organiser, the sequence is: publish the conditions, keep the evidence for every claim, and check the DIA guidance before adding a purchase to the mechanics.
- Misleading conditions are a Commerce Commission matter under its published guidance on promotions.
- Unsubstantiated advertising claims are an Advertising Standards Authority matter under the code.
- A scheme drifting toward gambling belongs to the Department of Internal Affairs.
- A contest without stated conditions or honest time limits fails every published test at once.
- Platform terms and an organiser's moderation decide disqualification before any regulator is involved.
Where the rules stand
The framework on this page treats a contest as three overlapping layers. The first layer is the organiser's own published rule set, which decides entry, voting and disqualification. The second layer is consumer protection: the Commerce Commission polices the conditions a promotion states, and the Fair Trading Act sits behind that. The third layer is advertising self-regulation, where the Advertising Standards Authority checks that claims in a promotion are substantiated. Where a scheme crosses into gambling territory, the Department of Internal Affairs guidance on sales promotions becomes relevant. Each layer fails separately, so a contest can be well run on one layer and still breach another.
What we refuse
This page explains what official bodies require and what they do not do. It is not legal advice, and it does not tell an organiser whether a specific scheme is lawful; only the regulators themselves or a lawyer can do that. We never assist with bending a contest's rules, creating extra entries, or masking activity from an organiser's moderation, and we make no promise that following this page leads to winning anything. Where a question depends on the exact wording of one organiser's terms, the answer lives in those terms, not here.
Typical questions
No single regulator covers them all. The Department of Internal Affairs publishes guidance on sales promotion schemes, the Commerce Commission governs the conditions a competition offering gifts or prizes must state, and the Advertising Standards Authority enforces the Advertising Standards Code on the claims an advertisement makes. Which of the three a contest answers to depends on its mechanics: a chance-based scheme with an entry purchase draws the DIA's attention, while a judged or publicly voted contest leans mostly on consumer and advertising rules. The DIA's fact sheet also names the Fair Trading Act as legislation that may additionally affect a sales promotion scheme.
The published demands are concrete rather than abstract. The Commerce Commission states that all conditions of a competition or promotion offering gifts or prizes, including any relevant time limits, must be clearly stated. The DIA warns organisers to be aware of other legislation such as the Fair Trading Act, which may also affect a sales promotion scheme. The Advertising Standards Code requires advertisers to hold evidence substantiating all claims made in an advertisement. Together these mean a prize draw or contest needs published conditions, honest deadlines, and promotional claims that can be backed by evidence.
There is no general contest permit for every prize competition, and this page does not rule on any single scheme. The Department of Internal Affairs regulates the gambling side and maintains a fact sheet on sales promotions, because schemes that attach prizes to purchases can approach gambling territory and may need a closer look under that framework. Consumer and advertising obligations apply regardless of any permit, since the Commerce Commission's conditions demand and the ASA's evidence demand do not depend on licensing. An organiser unsure where a specific design sits should consult the DIA's own guidance directly.
At minimum, every condition that applies, which is the Commerce Commission's own wording, and that includes any relevant time limits. In practice a rules page answers who may enter, what ends the contest, how winners are chosen, and when and how prizes are delivered. Each of those is a condition a participant can rely on, so each belongs in the published text rather than in an organiser's inbox. Where a deadline changes, the change belongs in the published rules too, because a stated closing time that the entry mechanics do not honour is a condition broken in public view.
Yes, and the difference follows the mechanics rather than the marketing. A contest decided by the entrant's own skill or by open public voting sits mainly under consumer and advertising rules, because merit or audience choice rather than chance produces the outcome. A random prize draw sits nearer the territory the Department of Internal Affairs regulates, which is why its sales promotion fact sheet exists, and a chance-based scheme requiring a purchase draws closest to the gambling side of the framework. An organiser who can state in one sentence whether skill, voting or chance decides their winner has located the relevant rules.
The consequence depends on which layer failed. Misleading or hidden conditions fall to the Commerce Commission, which has published exactly what it expects a promotion offering gifts or prizes to state. Advertising claims without evidence behind them fall to the Advertising Standards Authority under its code. A scheme that has drifted toward gambling falls to the Department of Internal Affairs. A participant facing a suspect result should first check the organiser's published conditions and the platform's own terms, since disqualification and moderation are decided there before any regulator is involved, and the vote counter and entry logs are what an organiser can actually inspect.
