One NZ offers a number of monthly plan options, with something to suit anyone who regularly uses their phone for data and/or calls. The plans are all open, meaning there is no fixed-term contract. Better yet, the 'to share' plans let family members use data allowances collectively. If you have outgrown prepay or want better value for money on data, one of One NZ's monthly plans could provide the solution.
Pay Monthly plans are the only option to bundle a wearable with. One NZ currently has the cheapest OneNumber Add-On for Apple Watch and Android watches at just $5 per month.

Pay Monthly plans are the only option to bundle a wearable with. One NZ currently has the cheapest OneNumber Add-On for Apple Watch and Android watches at just $5 per month.
Benefits:
- Pay monthly plans offer endless data allowances with corresponding data speed reductions at the data limit. Cheaper plans start reducing maximum speed at lower data limits than more expensive plans. Once Max Speed Data allowance is reached, data speed will be capped at 1.2Mbps only.
- Hotspot is now included in all Endless Data Pay Monthly plans without extra cost.
- You can roam overseas with your monthly plan data and minute allowances in 100+ countries for a fixed $10 per day, paid in addition to your monthly account fee.
- If you're part of a family looking for better value monthly plans, a new plan called 'Companion Plans' allows customers to share endless data plus unlimited calls and texts to NZ and AU numbers for only $37 per month. A family member paying for $73 Endless Plus or $88 One Plan can add up to 3 more for $37 and $42 per Companion plan per month accordingly. All companions must be on the same billing account and plan type as the Primary Plan. One NZ explains companion plans here.
- The fixed-limit data plans allow tethering/hotspot use, meaning you can use your phone (and the data allowance) to connect other device(s) to the internet.
- Minutes and TXT allowances include both New Zealand and Australia numbers.
- Plans currently offer a 12-month free trial of the One NZ Social Pass, which gives customers unlimited data when using Facebook, Instagram, Snapchat, Twitter and Pinterest.
- You can buy a new phone and spread the cost over 1-3 years, interest-free. Our Phone selection summary below explains the options in detail.
What to watch out for:
- Roaming outside of the included countries listed by One NZ won't be covered by the $10/day add-on rate, but since 11 July 2019, 16 more countries were added for monthly plan holders - read our roaming guide.
​
Network coverage
One NZ promotes that their mobile network now "covers approximately 99% of the population, with 4G coverage". This is quite a claim, but independent data, which we present below, confirms this. With 3G now a thing of the past, if you're in any main city or town, chances are you'll receive a constant 4G signal.
But, before going any further, the best idea is to see if where you live, where you work and other places you spend regular time in are covered by 4G. Visit the One NZ coverage map and insert your address, and cross-check using this tool to make sure you're covered.
One NZ also offers “4.5G” in many locations around New Zealand. It is reported to be 3X the speed of 4G. One NZ was the first New Zealand telco to start rolling out 5G mobile, which began in December 2019, and now covers around 69% of the population with 5G - you can read more about 5G here.
One NZ was the first NZ telco to offer satellite to mobile services, going further than traditional cell site coverage.

One NZ's 4G Network as at March 2026
Phone selection
One NZ recognises that the majority of New Zealanders looking for a new phone want an Apple, Samsung or Motorola. This is reflected on One NZ's website and its 57 stores around New Zealand. As is the case with any mobile network, new phones come with the following terms, conditions and optional extras:
- Interest-free terms (most of the time): One NZ offers 12, 24 and 36 months interest-free deals. What you pay is the total cost of the phone, the plan and an initial $99 deposit, divided by the number of months you select for the plan. For example, if your phone was $1,200 and you selected a plan costing $50 per month, your monthly cost would be $150 ($1,800 total cost, divided by 12 months).
- Phone Dollars are a new and unique thing from One NZ, which can help to reduce the cost of a new phone bought on Interest Free.
- Cancel a plan and you'll owe the balance left to pay on the phone: If you downgrade your plan, transfer it or leave One NZ altogether, you will have to repay the balance of the phone. For example, if you are 6 months through a 12-month plan and the phone originally cost $1,200, you'll need to pay $600 immediately to terminate.
​
Customer service
Like Spark and 2degrees, One NZ has a comprehensive online support system, which includes 24/7 phone support, live chat and an Auckland number if you're calling from overseas.

One NZ offers an option to put your mobile account on hold for up to 3 months. This means you will keep your number, but your account hibernates. You can only do this once in a 12-month period, but it offers flexibility if you are, for example, outside of New Zealand for an extended period of time. If you go overseas for a longer period, Reddit users recommend switching to Prepay, just making sure you keep it active for the whole time. |

The highest prices are paid for a fully working and undamaged phone, but they also accept broken phones. Depending on the condition, you can get anywhere up to 80% of a phone's fully working value.

Making a Complaint about One NZ to the TDR
Telecommunications Dispute Resolution (TDR) deals with complaints from consumers about any product or service provided by their telecommunications company. As a One NZ customer, you have the right to make a complaint. It's a free and independent service, but you will need to follow their process to progress a complaint.
Before you complain, you'll need to raise the issue with One NZ directly
The process of complaining with TDR is outlined here. Their helpful FAQs outline what you can expect, and case studies about recent complaints about telecommunication companies in general. The process is impartial, and once a decision is made, One NZ will (usually) abide by the ruling should it be in the wrong.
Before you complain, you'll need to raise the issue with One NZ directly
- One NZ is a member of TDR, but you will need to raise a complaint with their customer service first.
- Once you have done this, you must wait for a response.
- One NZ will respond, but if you are unable to agree with their response and your complaint becomes deadlocked, after six weeks has passed you can raise a complaint with the TDR.
