Shopping for a mobile plan in NZ can feel like a huge chore. Data caps, rollover, carryover, “endless” data, 28-day cycles, prepay, pay monthly… it’s a lot! And somehow you still end up paying more than you should.

We’ve done the hard yards for you. Below, we compare mobile plans across NZ’s main providers so you can see exactly what you get for your money.

Here’s what you’ll find:

• A side-by-side table of mobile plan prices in NZ
• What “best value” actually means, beyond the sticker price
• Where to find the cheapest unlimited data
• The sneaky costs to watch out for
• A quick checklist to help you pick the right plan

Why Cheap Mobile Plans Aren’t Always Good Value

A low monthly price looks great on a billboard. But cheap mobile plans often come with small data caps that run dry before the month is out.

Then the extras pile up. You pay for more data, you pay to check voicemail, and you might even pay a card fee every month. Some plans renew every 28 days, which sneaks in a 13th bill each year. 😬

Takeaway: The best value plan isn’t always the one with the lowest price. It’s the one that gives you the most for what you pay, with no surprises.

Mobile Plans NZ Comparison: The 2026 Price Table

Here’s how the selected providers stack up. We have grouped plans by provider and billing type so you can compare like with like. This guide focuses on Rocket Mobile and four large NZ mobile brands; it is not a complete list of every provider, MVNO or limited-time promotion in the market. 

Prices last checked on 23 October 2026. Skinny plans renew every four weeks, resulting in 13 renewals across a full year. Plans, promotions and inclusions can change, so check out each provider’s website before switching.

What the Comparison Tells Us

There’s a lot of numbers up there. Here’s what they actually mean for your wallet.

At $40-45, it’s unlimited vs a few gigs

For around $40, most providers give you somewhere between 3GB and 10GB of data.!

At the same price, Rocket gives you unlimited data. For $45, Rocket Plus bumps you up to 40Mbps, which is plenty for 4K streaming and online gaming. 🎮

Unlimited data pricing across the providers compared

If unlimited data is a must-have, here’s how the unlimited data plans compare:

Among the big four – Spark, One NZ, Skinny, and 2degrees – the next cheapest unlimited plan is $80 a month. That’s double the price of our Rocket plan!

Even at max speed, Rocket comes out on top

Want unlimited data with no speed tier at all? Rocket Max is $75/mth. That’s cheaper than every other unlimited max speed plan in our comparison, from 2degrees at $80 right up to Spark at $95.

Takeaway: Within the plans included here, Rocket offers lower-priced unlimited options across its listed speed tiers. The best choice will still depend on coverage, real-world speed, hotspot needs, billing preference, and any promotional pricing.

How to Judge “Best Value” (Not Just Cheapest)

Price matters. But here are the other things that decide whether a plan is good value:

1. Data you can actually use. A capped plan only helps if the data lasts the whole month.
2. The right speed for you. Most people don’t need max speed to scroll, stream, and video call.
3. Billing cycles. Monthly plans charge you 12 times a year. 4-weekly plans charge you 13.
4. Hidden extras. Think card fees, voicemail charges, and MMS costs.
5. Flexibility. Can you change or cancel your plan without fees or a contract?

Takeaway: Add up what you’ll really pay over a year, then compare what you get for it.

FAQs

What is the cheapest unlimited mobile data plan in NZ?

In this comparison of the big four NZ mobile providers, Rocket Mobile offers lower-priced unlimited plans than Spark, One NZ, Skinny, and 2degrees. Rocket starts at $40/mth for unlimited data at 10Mbps. Among the big four, the next cheapest unlimited plan is $80/mth.

Is unlimited data really unlimited with Rocket?

Yip! There’s no slowdown to unusable speeds after a cap. You just choose the speed that suits you. Usage is subject to our Fair Use Policy.

Are cheap mobile plans worth it?

They can be, as long as they give you enough data and no surprise extras. A capped plan that runs out mid-month often ends up costing more. That’s why unlimited data at the right speed is often the better deal.

Can I bring my number to Rocket Mobile?

Absolutely, and it’s free. Choose “Bring your number” when you order your SIM or eSIM, or move it across anytime later.

What mobile data speed do I need?

For browsing, messaging, music, and HD video, a fixed-speed plan may be sufficient. Higher speed tiers provide more headroom for 4K streaming large downloads, gaming and hotspot use. Actual performance varies by device, location, coverage, and network conditions.

What is the difference between unlimited and endless data?

The wording varies by provider. A plan may offer unlimited data at a fixed speed, or a max-speed allowance followed by reduced speed data. Review the speed policy and Fair Use Policy rather than relying only on the word “unlimited”.

Are four-weekly plans more expensive over a year?

A four-weekly plan renews 13 times in 52 weeks, while a monthly plan is normally billed 12 times a year. Compare the annual cost to understand the true difference.
