We get asked two questions about Tangem more than any others: is it safe, and is it legal to use in New Zealand? Short answers: yes, and yes. The longer answers are below.
If you are looking for a secure crypto wallet in NZ, this covers how Tangem protects your keys, where it sits under New Zealand law, and why holding your own keys is worth the small amount of effort.
What Tangem Wallet is
Tangem is a hardware crypto wallet in the shape of a bank card (or a ring). Your private keys are stored offline on a secure chip inside the card, not on an exchange and not on your phone.
With Tangem you can:
- hold crypto without having to write down a seed phrase (one is optional)
- keep full ownership of your assets, with no company holding them for you
- send and receive by tapping the card on your phone over NFC
You can see the current range at https://tangem.nz/.
Is Tangem safe?
1. A certified secure chip
Each card uses a Samsung secure element certified to EAL6+, the same type of chip found in bank cards and passports. The private key is generated on the chip and stays there. That means:
- the private key never leaves the chip
- nothing is stored in the cloud
- neither Tangem nor anyone else can access your key
Tangem firmware has been audited by Kudelski Security and Riscure, and it cannot be updated after manufacture, so nobody can push new code to your card. There is more detail in our article on Tangem security.
2. Offline signing
Tangem has no Wi-Fi, Bluetooth or USB. The card talks to your phone over NFC only while you are holding it there, and signs the transaction on the chip. The app then sends the signed transaction to the network. Remote attackers have nothing to connect to.
3. Seed phrase optional
A lost, photographed or stolen seed phrase is one of the most common ways people lose crypto. Tangem lets you skip the phrase entirely and use your backup cards instead. Each set has two or three cards that share the same key, so losing one is not a disaster. If you would rather have a phrase as well, you can create one.
4. Built to last
The cards are rated IP69K for water and dust, have no battery to wear out, and come with a 25-year warranty. You can put one in a drawer for years and it will still work when you need it.
Is Tangem legal in New Zealand?
Owning crypto is legal
Cryptocurrency is legal in New Zealand. Inland Revenue treats crypto-assets as property for tax purposes, not as currency. You can buy it, hold it and store it in a hardware wallet. Any gains may be taxable, so check IRD guidance or talk to an accountant about your situation.
No NZ registration needed for a wallet
No. Tangem is a device, not an exchange or a financial service. It does not hold your funds, run a trading platform or convert crypto to NZD.
New Zealand rules for crypto businesses, such as anti-money-laundering obligations, are aimed at exchanges and custodians that handle other people’s money. Keeping your own coins on your own wallet is a different thing, much like keeping cash in your own safe.
Why self-custody matters
When you hold your own keys:
- your crypto is not caught up in an exchange collapse or withdrawal freeze
- you can reach your funds even if a platform shuts down
- nobody else can move your assets
Exchange failures overseas have shown how quickly customers can lose access. A hardware wallet keeps your holdings under your control, whatever happens to the platform you bought them on.
The short version on safety and legality
Yes on both counts. The security rests on certified hardware and audited firmware, using a hardware wallet is lawful here, and you keep full control of your keys. It works for first-time buyers and for people who have held crypto for years.
