- Skinny $25 combo: 28-day pack, 5GB data + unlimited calls/texts

3. One NZ — Best for 5G
One NZ (formerly Vodafone NZ) has the most aggressive 5G rollout in NZ. If you have a 5G-capable phone and live in a major city, One NZ’s 5G is fast and widespread.

- Spark $55/month: ~30–40GB, unlimited calls/texts
- Spark $75/month: ~60–100GB, unlimited calls/texts

Key Questions When Choosing a Mobile Plan
1. Do you need rural coverage? If you travel frequently to rural NZ or live outside a main centre, Spark has the widest rural coverage. 2degrees is a strong second. One NZ has good regional coverage but less rural reach.
2. Is your phone still being paid off? If you’re paying for a handset as part of your monthly plan, you’re typically paying $20–$40/month more than a SIM-only plan for the same data. When your handset is paid off, switch to SIM-only immediately.
3. Do you need 5G? 5G is available in main NZ cities from all three networks. If you’re outside a 5G zone or have a 4G phone, this doesn’t matter.
4. How much data do you actually use? Check your data usage in your current provider’s app. Many people pay for 40GB/month and use 8GB. A cheaper plan with adequate data will save money without any practical change.
