Nearly every trade on maru goes smoothly, because our community is built on people looking out for one another. Still, a little care goes a long way, and knowing what to watch for lets you buy and sell with confidence. This guide walks you through the whole journey, from your first message to the moment money and goods change hands, so that trading in Auckland, Wellington, Christchurch and beyond stays as friendly as it should be.
For buyers#
Before you commit to anything, take a moment to get to know who you are dealing with. A seller’s profile tells you a lot: browse their posting history, look for any verified badges, and notice how quickly and clearly they respond. Someone who answers questions openly and has a track record of past listings is far more likely to be genuine than an account that appeared yesterday with a single, unusually cheap item. Don’t be shy about asking for more detail either. Requesting extra photos, asking about condition and any defects, and clarifying whether it’s pickup or delivery are all completely normal, and a trustworthy seller will happily oblige.
It’s also worth doing a quick bit of homework on the item itself. Search around for the typical price and compare it against similar listings, because a deal that seems too good to be true usually is. If a nearly-new phone is being offered for a fraction of its usual value, treat that as a reason to ask more questions rather than to rush in.
When it comes time to meet, choose somewhere public and well lit, ideally during daylight. Busy cafes and shopping-centre car parks work well, and many people find that the car park of a local police station makes an excellent, reassuring spot for a handover. Bring a friend along if you can, and let someone know where you’re going and when you expect to be back. Before you hand over any money, inspect the item properly: test electronics thoroughly, look for damage or wear, and check that any serial numbers match what was described in the listing.
Finally, stick to payment methods that are secure and traceable. Cash is perfectly fine for in-person meetings, and a bank transfer leaves a clear record if you’d prefer not to carry notes. What you should never do is pay in advance for something you haven’t seen, and you should steer well clear of anyone asking for a wire transfer or cryptocurrency, as those payments are almost impossible to recover.

For sellers#
Good selling starts with an honest listing. Describe the condition accurately, mention any defects or quirks up front, use clear and well-lit photos, and set a realistic price. Being straightforward not only builds trust, it also saves you awkward conversations later and earns you the kind of reviews that make future sales easier.
Protect your privacy as you go. There’s no need to share your personal banking details or your home address early on, so keep your conversations within maru’s messaging until you’ve arranged a meeting you’re comfortable with. When you do meet a buyer, apply the same common-sense care a buyer would: choose a public place in daylight, bring someone with you if possible, keep your phone charged, and trust your instincts if something feels off. On payment, count cash carefully and, if you’ve agreed to a bank transfer, confirm the money has actually landed in your account before you hand anything over. Offer a receipt where it makes sense, and keep a record of the transaction for your own peace of mind.

Warning signs#
Most scams share a familiar shape once you know it. Be wary of anyone who won’t meet in person, who asks you to pay in advance, or who pushes you to act quickly before you’ve had time to think. Unusual payment requests, such as gift cards, wire transfers or crypto, are a strong signal to walk away, as are stories that keep shifting or simply don’t add up. If someone repeatedly dodges reasonable questions or refuses to provide extra information, take that reluctance seriously. Trusting that instinct is often the single best protection you have.
A quick safety checklist#
Before you meet, run through these:
- Checked the other person’s profile and posting history
- Agreed a public, well-lit meeting spot (a café or police-station car park is ideal)
- Told a friend where you’re going and when to expect you back
- Brought someone along for higher-value items
- Phone charged, and every message kept inside maru
- Cash counted — or the bank transfer confirmed as received — before anything changes hands
If something goes wrong#
If a trade starts to feel wrong, the first thing to do is simply stop, even if that feels a little awkward in the moment. You are never obliged to go through with a deal. Report the person to us using the Report button on their listing or profile, and if you believe fraud has taken place, contact the NZ Police on 111. Keep hold of any evidence you have, including messages, photos and receipts, as these help both us and the police act quickly.
Extra care for high-value items and shipping#
For larger sums it’s worth taking a few additional precautions. Meeting at a bank can make big cash handovers safer and lets you verify a transfer on the spot, and getting a written receipt or a couple of photos of the exchange gives you a clear record if a question ever arises. When an item has to be posted rather than handed over, always use a trackable shipping method, insure anything valuable, and keep your proof of postage and receipts until the buyer has confirmed everything arrived as promised.
