The short answer
You can buy gold and silver with cash in New Zealand, but not in amounts of $10,000 or more. Since 11 May 2023 it has been unlawful for a dealer in high value goods to accept a cash transaction of $10,000 or more, and that prohibition specifically covers gold, silver and other precious metals.
This is not a dealer preference or a shop policy. It is a legal prohibition on the dealer, which is why no reputable dealer in the country will make an exception, however the request is framed.
What exactly is covered
The Department of Internal Affairs administers the rule. Two details catch people out:
- It is "$10,000 or more", not "over $10,000." A cash transaction of exactly $10,000 is caught.
- Cheques and other bearer negotiable instruments are caught as well. Swapping cash for a cheque does not change the position.
The goods covered are broader than bullion alone. The categories are jewellery, watches, gold, silver and other precious metals, diamonds, sapphires and other precious stones, motor vehicles, and boats.
You cannot split the payment
The prohibition applies to related cash transactions where the total reaches $10,000 or more. DIA gives layby as the example: two or more cash payments made on different days toward the same purchase are added together, and the total must not exceed the threshold.
So paying $6,000 today and $5,000 next week for the same gold bar is the same transaction in the eyes of the rule. Structuring a purchase to sit under the line is exactly the behaviour the rule exists to catch, and it is the sort of thing a dealer is obliged to notice.
What you can do instead
Nothing about this makes larger purchases difficult. Bank transfer is the normal route for anything substantial, and it has the useful side effect of creating clean records of what you paid and when — which matters if you ever need to evidence your position, as covered in our guide to tax on gold and silver in New Zealand.
Cash remains perfectly usable below the threshold.
Why you will be asked for ID
Precious metal dealers operate under New Zealand's anti money laundering framework. Depending on the size and nature of a transaction, that means verifying who you are before it completes — typically photo identification and, for larger amounts, proof of address and sometimes the source of the funds.
The instinct to bristle at this is understandable, but it is worth turning around: a dealer who does not ask is not offering you privacy, they are showing you they are not compliant. That is a reason to walk out, not to relax. The same checks that feel like friction are the ones that keep stolen and counterfeit metal out of the market you are buying into.
What happens to your information
Identification collected for AML purposes is held to meet record keeping obligations and is handled under the Privacy Act. It is not a marketing list and it is not published.
What it is not, either, is a guarantee of secrecy. Reporting entities have legal obligations that can require them to report certain activity to the authorities, and those obligations are not something a customer can opt out of or a dealer can waive. Any dealer promising you a completely untraceable purchase is either misunderstanding the law or ignoring it.
Separately, buying bullion is not itself a taxable event and is not "reported to IRD" as a purchase — but what happens when you sell is a different question, and one worth understanding in advance.
Buying in person in Christchurch
If you would rather hand over funds and walk out holding the metal, an in person purchase at a showroom does that. Bring valid photo identification, allow time for verification on larger amounts, and arrange bank transfer in advance if the purchase will be $10,000 or more.
