Choosing a mobile provider in New Zealand is tougher than ever in May 2025. Spark, Vodafone NZ (now trading as One NZ), and 2degrees are constantly upgrading their offers to stay competitive. Let’s break down their latest mobile data deals to see who is delivering the best value.
Current Data Deals Overview (May 2025)
Here’s a quick snapshot of what each provider is offering this month:
| Provider | Plan Name | Data Allowance | Price | Special Features |
|---|---|---|---|---|
| Spark | Endless Mobile Value | Unlimited (speed reduced after 100GB) | $79.99/month | 5G access, Spark Sport included |
| Vodafone NZ (One NZ) | Endless Play | Unlimited (speed reduced after 120GB) | $75/month | 5G, One Premium streaming bundle |
| 2degrees | Max Speed Plan | Unlimited (speed reduced after 90GB) | $70/month | Carryover data, free Data Hour daily |
Spark – Premium Add-Ons and Wide Coverage
Spark continues to lead with strong nationwide coverage, including robust 5G rollout in major urban areas. Their “Endless Mobile Value” plan offers full-speed data up to 100GB, after which speeds slow but remain usable for basic browsing. Subscribers also get free Spark Sport streaming and half-price Netflix for the first six months.
Spark’s edge is in network reliability and extras. For professionals needing uninterrupted data access and entertainment bundles, Spark remains a solid choice.
Vodafone NZ (One NZ) – Entertainment Lovers’ Delight
Vodafone NZ, now officially rebranded as One NZ, focuses heavily on bundling entertainment services with their plans. Their “Endless Play” plan gives customers 120GB of full-speed data before slowing.
The plan includes a One Premium subscription, which bundles streaming platforms like Neon and Sky Sport Now — perfect for users who are heavy on video streaming and want maximum entertainment without extra subscription costs.
One NZ also shines with competitive 5G speeds in Auckland, Wellington, and Christchurch.
2degrees – Value-Focused with Flexibility
2degrees’ “Max Speed Plan” hits the sweet spot for those looking to save without sacrificing too much. Although high-speed data is capped at 90GB, it’s still generous for most users. Plus, features like Daily Data Hour (an hour of unlimited full-speed data each day) add real value for users who can plan heavy usage bursts.
Another big win for 2degrees is carryover data. If you don’t use all your data, it rolls into the next month, something neither Spark nor One NZ offers.
2degrees has expanded its 5G coverage significantly in 2025, especially in regional areas where competitors often lag.
How Do They Compare in Terms of Coverage and Speed?
When it comes to coverage, Spark holds a slight edge nationally, particularly in rural areas. Vodafone NZ has the fastest average 5G speeds, according to the latest Ookla Speedtest reports from April 2025. Meanwhile, 2degrees is closing the gap quickly with aggressive network expansion in Tier-2 cities.
Reliability rankings based on independent tests:
- Spark: Best for nationwide coverage.
- Vodafone NZ: Best for 5G speed in metro areas.
- 2degrees: Best for regional expansion and affordable data.
Conclusion
If you prioritize coverage and bundled entertainment, Spark should be your pick. If streaming and value-for-money entertainment subscriptions matter most, Vodafone NZ (One NZ) offers the better package. But if flexibility, daily data boosts, and overall savings appeal to you, 2degrees stands out.
Choosing the best provider really comes down to your personal data usage habits and where you live.
