How we rate mobile plan providers

Our review compares mobile providers on customer satisfaction, so you can discover what other Kiwis think about our compared plan providers before you sign on with one of them. Think of it like asking hundreds of your closest mates which mobile plan provider they think is best!

Canstar Blue surveyed 2250 Kiwis who have an account with a mobile provider and asked for their feedback on their mobile provider.

  • The outcomes reported in these ratings are measured via accredited research panels managed by Qualtrics.

Respondents rate their satisfaction with their providers from zero to ten, where zero is extremely dissatisfied and ten is extremely satisfied. Brand satisfaction was rated by respondents on the following criteria:

  • Overall Satisfaction: measures consumer satisfaction with a provider as an individual score NOT a combined total of all criteria.
  • Accessibility of the Provider: it’s easy to contact the provider to make a query or for help, either online, in person, in-store, or over the phone.
  • Assistance managing data: the mobile plan provider provides tools and data to allow customers to easily manage their data usage, and to ensure they’re on the plan best-suited to their data needs.
  • Billing: bills provides accurate details of phone usage and costs, so it’s easy to work out if you’re on the correct plan for your phone needs.
  • Customer Service: the customer service provided by the mobile provider is helpful, prompt and of a high standard.
  • Network Coverage: the mobile phone provider’s network offers good access to 4G signals in both urban and rural locations, and is making progress expanding its 5G coverage.
  • Value for Money: the provider’s plans offer great value for money when comparing services and extras with price.

The winning brand is the one that receives the highest Overall Satisfaction rating once all the scores from the Overall Satisfaction criteria are combined and averaged.

  • Overall Satisfaction is asked as a specific question and represents an individual measure, not a combined total of all criteria.
  • When we cannot determine a clear winner from the criteria for the Overall Satisfaction rating, we will then look at the other criteria measured in the rating.
    • The brand with the highest number of five-star ratings within the supporting criteria will become the five-star recipient in overall satisfaction, and thus win the award. If a clear leader still cannot be determined from the supporting criteria, joint winners will be declared.

Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.

  • 2degrees
  • Spark
  • Slingshot

The only monthly phone plan provider in this year’s ratings to score a top 5-Star rating for Overall Satisfaction, it achieves nearly a clean sweep of top ratings across all categories. Its one 4-Star rating is for the coverage of its network, as it continues to roll out 5G across the country to match its already excellent 4G network.

Ratings Results

Slingshot isn’t a big standalone telco, but its mobile deals are popular with its broadband and power customers. It earns its highest ratings for its Customer Service and Billing.

Choosing the Right Mobile Plan Provider

It’s always interesting comparing consumers across Canstar’s research. And our latest mobile awards have revealed an interesting distinction between prepaid and plan mobile consumers: plan customers are a lot more reliant on data. Across all data-related fields in our research – from navigation, to financial, banking and social media and communication apps – use is about 10% higher among phone plan users than prepaid users.

This is a reflection of the monthly plans available, which are being constantly updated. The majority of monthly plans now come with unlimited data, albeit with speed caps, which is reflected in our research.

In last year’s award research just over a third of consumers (37%) had endless data, this year it’s nearly half (46%). And, as a consequence, the percentage of monthly plan users who consider provider assistance in managing data as very important has slumped, from 9% to just 5%.

Although one statistic remains the same: the overwhelming number of mobile phone customers who cite value for money as the biggest driver of their satisfaction with their phone provider.

Here’s the full rundown of what the consumers in our survey say are the main things they consider when rating their mobile plan providers:

  • Value for Money: 28%
  • Customer Service 23%
  • Network Coverage: 16%
  • Accessibility of Provider: 15%
  • Billing: 12%
  • Assistance Managing Data: 5%

What mobile networks are there in NZ?

There are three main mobile networks in the country, which were built by 2degrees, Spark and One NZ (formerly Vodafone). Although both 2degrees and Spark sold off their tower assets recently, they still use the networks they built.

In major centres, there’s very little difference between the three networks. However, in rural and remote areas coverage can vary dramatically. And then there’s 5G, which is more limited in its reach, even in major centres.

Here a rundown of the networks and which other monthly plan providers use them:


Network reaches 97.5% of New Zealanders (with 4G at around 97%). Spark’s network coverage map can be found here.

One NZ

Network covers over 98.5% of the population (with 4G at over 96%). One NZ’s network coverage map can be found here.

2degrees (Slingshot)

Network covers 98.5% of the places New Zealanders live and work (with 4G at over 96%). 2degrees’ network coverage map can be found here.

Prepaid vs postpaid mobile plans


Prepaid plans are phone plans that require you to prepay for the telco service: i.e. you pay in advance for phone services to use within a set time period. Once that expiry period is over, you need to recharge your plan in order to continue your service. If you use up some of your data/text/talk allocations before the expiry period, you will need to either recharge your plan, wait until your next recharge (and not have certain services until then) or purchase an add-on for an additional cost, such as extra data, if applicable.


Postpaid plans differ in that you pay after using your phone plan allocations. Typically, you receive a monthly bill from your telco, usually on the same date, that you have to pay by a certain date. If you have used more than your plan’s inclusions, you might incur additional charges on your bill.

The main advantage of a postpaid plan is that you’ll never be left unable to make a call, send a text message, or use mobile data to chat online. If a prepaid plan expires, you need to spend extra money immediately to get your service back up and running. However, postpaid plans allow you to keep using your service, and simply settle the bill later.

The main disadvantage of postpaid phone plans is the potential to blow out your budget if you’re not careful. Make sure that you know exactly what you will need to pay for going over your plan’s inclusions, keep an eye on your data use, and make sure that exceeding your monthly allowance doesn’t become a habit. If it does, you could be better off upgrading your plan, rather than paying extra in excess charges.

Prepaid vs postpaid mobile plans

The safety net of being able to make calls whenever you need to means that postpaid phone plans are probably a good idea for those who use their phone a lot.

If keeping close tabs on your spending is important to you, then prepaid may be the wise alternative. But when it comes to ease of use and maximum bang for your buck, it’s hard to look past postpaid plans.
