A charity raffle only works if people believe the draw itself is real: that the winning ticket was genuinely picked at random, by someone with no reason to pick a particular number. That belief isn't just good practice, it's a legal requirement, and it's worth knowing exactly what the rule says and what it looks like in practice.
Under the Gambling Act (Lottery) Game Rules, results have to be declared "by blind selection of included numbers, under supervision of an independent witness." That's not a charity's internal policy choice, it's a statutory rule, and it applies to every licensed Class 3 lottery regardless of size. The independent witness can't be an employee or volunteer of the charity running the draw. Their entire job is to be someone with nothing to gain from any particular outcome.
This isn't an abstract requirement charities quietly work around. Coastguard draws its lotteries at the Auckland Marine Rescue Centre with NZ Police in attendance, and the draw is open to the public to watch in person. The Heart Foundation holds its declarations at a fixed time and address, published in advance, with results afterward printed in a national newspaper. Northern Rescue's draws happen at a physical location under the same independent-witness rule, with results published across the NZ Herald, the charity's own website and social media.
None of this is theatre. It's the mechanism that turns "trust us" into something a member of the public could actually go and verify.
A charity could, in theory, run every other part of a lottery perfectly, a genuine cause, a real prize, an honest ticket count, and still get this one part wrong. If the draw itself isn't independently witnessed, none of the rest of it is verifiable from the outside. This is also exactly the kind of detail worth checking before buying a ticket: a legitimate lottery will always be specific about who supervised the draw and where results were published, because it has nothing to hide about it. A page that's vague on this point, or silent on it entirely, is a real warning sign.
If you're checking a lottery yourself, the details to look for are concrete: a named draw location, a specific supervising role (often police, sometimes a solicitor or other independent professional), and a stated publication channel for results, not just "winners will be notified." All of the current listings in our own Lottery Directory publish this information plainly, because it's not optional, and it's one of the fastest ways to separate a properly run lottery from one that isn't.
