What is the cheapest mobile phone plan in NZ?
Best prepay plans under $20
New Zealand’s cheapest prepay plan comes from Skinny Mobile at $16 per month for 1.5GB data and unlimited texts. Warehouse Mobile also offers a $16 prepay with 1GB, while 2degrees starts at $19 for 1.5GB. All three are prepaid — no contract, no credit check.
- Skinny $16 prepay: 1.5GB data, unlimited txt, 30-day expiry (Mobile Phones NZ (plan aggregator))
- Warehouse Mobile $16 prepay: 1GB data, unlimited txt (Mobile Phones NZ (plan aggregator))
- 2degrees $19 prepay: 1.5GB data, unlimited txt (MoneyHub NZ (consumer finance guide))
For light users spending under $20 a month, a prepay plan is almost always cheaper than a monthly contract — even if you use the same network.
Cheapest monthly plans under $30
If you prefer a monthly bill with more data, Skinny’s $26 plan (3GB data, unlimited txt and calls) is the cheapest monthly option. Warehouse Mobile’s $27 plan offers 3GB, and 2degrees’ $28 plan comes with 3.5GB. These plans do not require a 24-month lock-in.
- Skinny $26 monthly: 3GB, unlimited calls/txt (Canstar (financial comparison site))
- 2degrees $28 monthly: 3.5GB, unlimited calls/txt (MoneyHub NZ (consumer finance guide))
The implication: For under $20 you get a basic data allowance — enough for messaging and light browsing, but not for streaming. The extra $10–12 buys you a few more gigabytes and unlimited calls.
What mobile plan has the best coverage in NZ?
Spark coverage map vs One NZ vs 2degrees
All three major providers claim to cover over 95% of the populated New Zealand population with 4G. Spark leads at ~98.5%, according to its official coverage page. One NZ follows at ~97%, and 2degrees reaches ~95% — weaker in rural areas.
- Spark: 98.5% of population coverage (Spark NZ (official carrier))
- One NZ: ~97% (One NZ (official carrier))
- 2degrees: ~95% (MoneyHub NZ (consumer finance guide))
Rural vs urban coverage differences
The gap widens outside main centres. One NZ is often rated stronger in regional and rural areas, while Spark excels in cities. Both have roaming agreements, but 2degrees relies on a partnership with One NZ in some remote spots.
MoneyHub NZ (consumer finance guide) notes that “One NZ is stronger in rural areas, Spark better in cities.”
What this means: Coverage varies most outside main centres — check each carrier’s coverage map for your specific address before choosing.
Which mobile phone company is the best in NZ?
Consumer NZ 2024 winner: 2degrees
The Consumer NZ 2024 mobile provider survey ranked 2degrees as the top overall provider for customer satisfaction. The survey evaluated value for money, network reliability, customer service, and contract terms.
“2degrees came top overall for customer satisfaction.”
— Consumer NZ (survey 2024), cited by MoneyHub NZ (consumer finance guide)
Best for customer service vs best for reliability
Different providers lead in different areas. One NZ has the largest 5G footprint, covering about 200 towns. Spark wins on network reliability and population coverage. 2degrees scores highest on price and customer service.
- One NZ: largest 5G coverage (~200 towns) (One NZ (official carrier))
- Spark: best network reliability and overall coverage (Spark NZ (official carrier))
- 2degrees: top customer satisfaction and value (Canstar (financial comparison site))
The pattern: There is no single “best” — your choice depends on whether you prioritise price, coverage, or speed.
What is the cheapest but good phone plan?
Best value plans balancing cost and quality
For a good all-rounder, Skinny’s $26 plan (3GB, unlimited calls) and 2degrees’ $35 plan (6GB) are frequently recommended. Warehouse Mobile’s $35 plan offers a generous 10GB — best for data-heavy users on a budget.
- Skinny $26: 3GB, unlimited calls/txt — best for light users (Canstar (financial comparison site))
- 2degrees $35: 6GB, unlimited calls/txt — good middle ground (MoneyHub NZ (consumer finance guide))
- Warehouse Mobile $35: 10GB, unlimited calls/txt — best value per GB (Mobile Phones NZ (plan aggregator))
Recommended plans for light and moderate users
If you mostly use messaging and maps, a $16–$19 prepay works fine. For moderate daily use with some streaming, the $35 tier from 2degrees or Warehouse Mobile gives enough data without hitting throttling limits.
Why this matters: A middle-tier plan often gives the best balance of data and reliability without paying for unlimited.
What are the best unlimited mobile data plans in NZ?
Unlimited data plan pricing 2025
Truly unlimited plans (no speed cap after a threshold) are rare. Spark Endless Data at $69/month is one of the few that offers genuine unlimited high-speed data, no throttling, and includes Spotify Premium. One NZ Unlimited Max at $85/month is also truly unlimited with international calling. 2degrees Unlimited Talk & Data at $75/month caps high-speed data at 120GB then throttles to 1Mbps.
- Spark Endless Data: $69/month, truly unlimited high-speed data, no throttling (Spark NZ (official carrier))
- One NZ Unlimited Max: $85/month, truly unlimited, international calls (One NZ (official carrier))
- 2degrees Unlimited: $75/month, 120GB high-speed then 1Mbps (Mobile Phones NZ (plan aggregator))
- Warehouse Mobile Unlimited: $45/month, 50GB high-speed then 1Mbps (Canstar (financial comparison site))
Throttling policies and fair use caps
Most unlimited plans have a “fair use” cap. Exceeding it reduces your speed to around 1Mbps — enough for messaging and music but not for HD video. Spark is the notable exception with no speed reduction. MoneyHub NZ (consumer finance guide) recommends Mighty Mobile’s Fast plan (10Mbps cap) as a budget alternative.
The catch: Most “unlimited” plans have fair use caps — exceeding them slows your speed, sometimes to 1Mbps. If you stream daily, Spark’s truly unlimited plan may be worth the premium.
Four plans, one pattern: the price of true unlimited starts at $69, and every “unlimited” plan below that has a throttle threshold.
| Provider | Price/month | High-speed cap | Throttled speed | 5G included |
|---|---|---|---|---|
| Spark Endless Data | $69 | No cap (truly unlimited) | None | Yes |
| One NZ Unlimited Max | $85 | No cap (truly unlimited) | None | Yes |
| 2degrees Unlimited | $75 | 120GB | 1Mbps | Yes |
| Warehouse Mobile Unlimited | $45 | 50GB | 1Mbps | Yes |
| Skinny (no unlimited option) | — | — | — | — |
Unlimited plans with throttling after 50–100GB can feel slower than a capped plan if you’re a heavy streamer. Check the fine print on fair use policies before signing up.
Pros and Cons: Unlimited vs capped plans
Upsides
- No stress about running out of data — even after throttling, basic services still work
- Best for heavy streamers, remote workers, or households without home broadband
- Usually includes unlimited calls and texts
Downsides
- Higher monthly cost — $45 to $85 compared to under $30 for capped plans
- Throttling after fair use cap makes HD video and large downloads impractical
- Not all plans include tethering — check provider terms
What others are saying
“One NZ has expanded its 5G network to 200 towns across New Zealand.”
— One NZ press release (2024), cited by One NZ (official carrier)
“Spark’s mobile network covers 98.5% of the New Zealand population.”
— Spark NZ coverage page, Spark NZ (official carrier)
“2degrees came top overall for customer satisfaction.”
— Consumer NZ survey 2024, cited by MoneyHub NZ (consumer finance guide)
For the average New Zealander, the trade-off is simple: if you rarely exceed 5GB, a prepay or budget plan from Skinny or Warehouse saves money. If you stream daily, Spark Endless Data offers true unlimited without throttling — but you pay for it. Check coverage first, then compare data caps. For the budget-conscious in urban areas, the cheapest prepay is enough; for rural users, One NZ’s stronger regional coverage may be worth the extra cost.

Frequently asked questions
How often do mobile plans change in NZ?
Providers adjust pricing and data allowances several times a year. MoneyHub updates its comparison page regularly — last major update was April 2026 (MoneyHub NZ (consumer finance guide)). Always check the date on any comparison.
Can I switch mobile providers and keep my number?
Yes. Number porting is free and usually takes a few hours. The process is regulated by the Commerce Commission. You don’t need to cancel your old plan first — the new carrier handles it.
Do MVNOs like Skinny use the same towers as Spark?
Yes. Skinny operates on Spark’s network, and Warehouse Mobile uses 2degrees’ network. However, MVNO customers may experience deprioritization during peak times (MoneyHub NZ (consumer finance guide)).
What is the average monthly cost of a mobile plan in NZ?
Most Kiwis spend between $45 and $55 per month (Canstar (financial comparison site)). That includes prepay users, so monthly contract users often spend more.
Is unlimited data truly unlimited in NZ?
Only Spark Endless Data ($69) and One NZ Unlimited Max ($85) offer truly unlimited high-speed data with no throttle. All other “unlimited” plans have fair use caps (50–120GB) after which speed drops to ~1Mbps (Spark NZ (official carrier)).
Which provider offers the best family or multi-line discount?
2degrees offers the best multi-line discounts on its unlimited plans, according to Mobile Phones NZ (plan aggregator). Spark and One NZ also have family plans but with smaller savings.
Do prepay plans include international calling?
Most cheap prepay plans (Skinny $16, Warehouse $16) include unlimited NZ texts and calls but not international. 2degrees prepay adds some international minutes on higher tiers.
