Our verdict
One is a New Zealand network that suits households wanting a cheap line with terms as short as 1 month. Its prepaid entry plan, Starter Prepay, at NZD 10 is the price most readers meet first, and the range keeps plans short term and easy to leave.

Pros and cons
Pros
- The entry plan, Starter Prepay, costs NZD 10 with terms as short as 1 month, so a trial line is cheap to start.
- Data rollover and hotspot sharing come as standard, so a quiet month is not wasted and a phone can share its connection.
- One is the network itself, network, so the plan and the people answering questions come from the same company.
- Support runs on chat, phone and help centre, with chat, phone and a help centre.
- No credit check is required, and a multi line discount applies, which suits a household setting up several numbers.
Cons
- Europe roaming is paid, and the service covers NZ alone, so travel adds cost rather than coming bundled.
- The unlimited plan is the weak spot: at NZD 88 the brand sits 159 of 173 on that measure.
- A term contract is not among its billing options (rolling and prepaid), so a reader who wants a fixed commitment has to look at GETESA, which lists prepaid and contract.
Who it suits
- Households after the cheapest sensible way onto a New Zealand network, with entry at NZD 10 and no long term.
- Families running several lines, since a multi line discount applies and billing stays on rolling and prepaid.
- Light data users who like rollover and a full speed cap before paying NZD 88 for unlimited.
Who should look elsewhere
- Anyone who needs a term contract, because One bills on rolling and prepaid while GETESA pairs prepaid with contract billing on prepaid and contract.
- Readers on a tight budget who want unlimited data cheaply, since NZD 88 is a heavier monthly spend and Lonestar Cell MTN offers prepaid alongside contract on contract and prepaid.
How it compares on our data
On price from, One ranks 92 of 258 brands. The unlimited measure sits differently, at 159 of 173. Readers weighing entry price against renewal price get a different answer from each measure, and the unlimited figure is the one to check before committing to heavy use.
Core features
Sim only options are available, and so is a fifth generation network. An eSIM is supported alongside a physical SIM, and wifi calling is available, which helps where the mobile signal indoors is weak. Data rollover is on for prepaid, so unused data carries into the next cycle, and hotspot sharing is available for a tablet or laptop. No credit check is required to take a plan, and a multi line discount applies for households with more than one line.
Plans and prices
Starter Prepay is the entry plan at NZD 10, carrying a modest data allowance and running month to month. Endless Plus sits in the middle with a large data cap served at full network speed on an open term. The unlimited option, One Plan Unlimited, costs NZD 88 and is also open term, so the figure readers see at entry is the figure that renews. All prices are quoted in New Zealand dollars.
The company behind it
The company behind One is One New Zealand Group Limited, so the arrangement sits with the operator itself rather than a separate reseller. Support runs on chat, phone and help centre, and each of those routes points back to the same company rather than an outsourced desk. A household with a billing query or a network fault therefore deals with a single organisation throughout, which matters on plans that renew without notice.

Frequently asked questions
How much does the cheapest One plan cost?+
Starter Prepay is the entry point at NZD 10, quoted in New Zealand dollars, and it runs month to month rather than on a long term. Billing on One plans is rolling and prepaid, so a top up does not tie you into a contract and the price met at entry is the price that recurs.
How much is the unlimited data plan?+
One Plan Unlimited costs NZD 88 a month on an open term, so the figure readers see at entry is the figure that renews. Endless Plus sits below it as the capped option, serving a set data limit at full network speed.
Do I need a credit check to join One?+
No credit check is required to take a One plan, so approval does not rest on your credit file. Billing runs on rolling and prepaid, which keeps the arrangement small and reversible. A prepaid top up leaves no long tail of account history to manage if the line is not working for you.
How long is the contract, and can I leave early?+
Terms run as short as 1 month, so the entry plan renews month to month rather than locking in a long term. The wider range is sold on an open term, and billing covers rolling and prepaid. Nothing in the arrangement needs a notice period, which makes switching away a decision you can take at any renewal.
Does One work abroad, and is roaming included?+
Europe roaming is paid, so trips to the continent add cost to the bill rather than coming bundled. The service is built for NZ, a single market, so the SIM covers its home country and everywhere else is a pay as you go extra.
Can I get an eSIM and will calls work indoors?+
An eSIM is available, so a new line can be activated on a handset without waiting for a card in the post, and travel setups are easier to manage. Wi-Fi calling is supported as well, which keeps calls working where the mobile signal indoors is weak. Unused data rolls over on rolling and prepaid plans, so a quiet month is not wasted.
How do I contact One if something goes wrong?+
Support runs on chat, phone and help centre, so a question can go to chat, phone or the help centre without going through a third party. The company answering is One New Zealand Group Limited, the same legal entity that supplies the mobile service, so a billing query and a network fault land in the same place.
Is there a discount for more than one line?+
A multi line discount applies, so a household running several numbers can bring the total down rather than paying full price on each line. That matters most on the NZD 88 tier, where each added unlimited line would otherwise cost the most. Data rollover applies too, so extra lines do not need exact data estimates.
