When something goes wrong with an online purchase, the single most important question is not what you bought, it is who you bought it from. Buying from a New Zealand business gives you strong, automatic rights under the Consumer Guarantees Act and the Fair Trading Act. Buying from an overseas business puts you largely outside those laws, so you lean on the platform and your card instead. Buying from a private seller on an auction or social marketplace strips away most of the consumer law entirely and moves you closer to buyer beware. The same faulty phone can leave you fully protected, partly protected or barely protected depending only on the seller. This guide explains each situation, how a card chargeback can rescue a bad purchase, and how to buy safely so it does not come to that.
| You buy from | Main protection | If it goes wrong |
|---|---|---|
| NZ business | Consumer Guarantees Act and Fair Trading Act | Repair, replace or refund from the retailer |
| Overseas business | Platform policy plus your card chargeback | Seller's return policy, then chargeback or the platform |
| Private seller (not in trade) | Contract and Commercial Law Act 2017 | Goods must match the description, or you can cancel or claim |
This is the strongest position. Any business selling to you in New Zealand, whether it has a shop or is online only, must meet the Consumer Guarantees Act 1993 (CGA). Goods must be of acceptable quality, fit for purpose, match their description and last a reasonable time for their price and type. These rights are automatic and cannot be signed away by fine print or a "no returns" sign.
A .co.nz web address or prices in dollars does not prove it. Check for a New Zealand company name, a physical address and a GST number. Some sites that look local are overseas sellers using a marketplace. If the goods ship from overseas and there is no NZ entity behind the sale, you are in the overseas situation covered next, not the CGA.
Sites like large global marketplaces and direct-from-overseas retailers can be cheap and convenient, but New Zealand consumer law is very hard to enforce against a seller that has no presence here. You are not without options, they are just different ones.
Since 1 December 2019, overseas businesses that sell low value goods to New Zealand shoppers generally have to register for and charge GST. A low value good is a physical item valued at NZ$1,000 or less (excluding GST). In practice this means:
Being charged GST does not make an overseas purchase a New Zealand sale. It is just tax. Your repair, replace and refund rights still depend on the seller's own policy and the platform, not the CGA.
With an overseas purchase, whatever the seller offers is what you get. Read the return window, who pays return shipping (often you, and it can cost more than the item), and any warranty terms before you buy. There is no CGA backstop if the policy is stingy.
The Disputes Tribunal and the Commerce Commission deal with sellers connected to New Zealand. Taking action against a company in another country is usually not realistic for a single online order, which is exactly why paying by card and using the platform's protection matter so much.
When you buy from an individual selling their own used gear on an online marketplace, the Consumer Guarantees Act and the Fair Trading Act do not apply. This is closer to buyer beware, but you are not completely unprotected.
If someone is really running a business, selling regularly or buying stock to resell, they are "in trade" even on a marketplace, and the CGA and Fair Trading Act do apply to them. A one-off sale of a personal item is a private sale; a high-volume seller is not. When it is unclear, look at how many items they sell and how they describe themselves.
Where a marketplace runs its own payment system, it usually comes with a buyer protection scheme that can cover you if your item does not arrive, is not as described, or arrives broken. Each platform sets its own cover limit and conditions, so check what yours actually offers before you rely on it. That protection is one of the main reasons to pay through the platform rather than off to the side, and it generally applies whether the seller is a business or a private individual.
A chargeback is your bank reversing a card payment under Visa or Mastercard rules. It is separate from your CGA rights and is especially useful for overseas sellers and businesses that vanish.
If a New Zealand business or a NZ-based private seller will not put things right, the Disputes Tribunal hears claims up to $60,000 (raised from $30,000 on 24 January 2026). Filing fees are $62 for claims under $2,000, $124 up to $5,000, $248 up to $30,000 and $496 above that. No lawyers are involved. For free advice first, call the Citizens Advice Bureau on 0800 367 222.
These four New Zealand examples show how the same kind of problem plays out very differently depending on who you bought from. The people are made up; the rules and figures are real and hand-checked.
Situation: Priya bought a $1,199 dishwasher online from a New Zealand retailer. It failed at 18 months. The 12-month manufacturer warranty had ended, and she had declined a $199 extended warranty at the till.
Situation: Tom bought headphones for NZ$260 from a large overseas marketplace. GST was added at checkout.
Tom paid by credit card, so a chargeback was available. Had he paid by a method with no chargeback, his only route would have been the seller's own policy, which offered him far less.
Situation: Aroha bought a used laptop for $700 from a private seller on an online marketplace. The listing said "battery holds a full day, no faults". The battery was dead and would not hold charge.
Situation: Hemi paid $450 by Visa credit card to an overseas online store for a bike part. The store took the money, sent no tracking, and stopped answering emails.
Paying by card and acting quickly turned a total loss into a full refund. A bank transfer to the same store would have left Hemi with no way to get the money back.
