Unlimited Data Plans - Frequently Asked Questions
What's the best unlimited data plan in New Zealand?
Answer: Spark Endless Data ($69/month) is the best unlimited data plan if you need truly unlimited high-speed data. For budget users, Warehouse Mobile Unlimited ($45/month) offers the best value with 50GB of high-speed data.
Key comparison:
- Spark Endless Data: Truly unlimited, no throttling, includes Spotify Premium
- Warehouse Mobile: 50GB then 1Mbps, no contract, cheapest option
- One NZ Unlimited Max: Unlimited + international calling to 30+ countries
- 2degrees Unlimited: 120GB then 1Mbps, best family discounts
Are New Zealand unlimited data plans really unlimited?
Answer: Only Spark Endless Data and One NZ Unlimited Max are truly unlimited with no speed restrictions. Other "unlimited" plans have fair usage policies:

- Warehouse Mobile: Data slows to 1Mbps after 50GB
- Truly unlimited plans: Spark ($69) and One NZ ($85) have no throttling
For most users, 50-120GB of high-speed data is sufficient, but heavy streamers need truly unlimited plans.
