Frequently Asked Questions

Is prepaid or postpaid cheaper in New Zealand?

Prepaid is typically cheaper for light users (under 5GB/month), with plans starting from $19/month. Postpaid offers better value for heavy users (15GB+/month) due to lower per-GB rates and unlimited options. The crossover point is usually around 8-10GB monthly usage.

Can I keep my phone number when switching from prepaid to postpaid?

Yes, you can keep your number when switching between prepaid and postpaid plans. Request a PAC (Porting Authorization Code) from your current provider and give it to your new provider. The process typically takes 1-2 business days and is free in New Zealand.

Do prepaid plans have worse coverage than postpaid?

No, prepaid and postpaid plans use the same network infrastructure and have identical coverage. However, postpaid customers may receive priority during network congestion, and some prepaid MVNOs might have slightly slower speeds during peak times.

What credit score do I need for a postpaid plan?

Most NZ providers require a "Good" credit rating for postpaid plans. If you have limited credit history or poor credit, you may need to pay a bond (usually $200-500) or consider prepaid options which don't require credit checks.

Can I get a phone on a prepaid plan?

Most prepaid plans require you to bring your own phone or buy one outright. Some providers like Spark and 2degrees offer prepaid phone bundles, but you can't finance phones on prepaid plans like you can with postpaid contracts.

Which major NZ providers offer both prepaid and postpaid?

All major NZ providers offer both options: Spark (prepaid and postpaid), One NZ (prepaid and postpaid), 2degrees (prepaid and postpaid). MVNOs like Warehouse Mobile and Skinny focus primarily on prepaid, while some business-focused providers specialize in postpaid.
