Three Must-Know Prepay Facts

Rollover and Carryover allowances are only valid if you renew your pack when it expires

You may have 2GB owed and countless minutes, but if you don't renew your pack when it expires, you will lose all your balances. This means you can't get a plan, save balances and use them afterwards. There is no exception to these terms.

Casual rates can be very expensive

If and when you use up all of your pack's allowances, you can either buy a new pack, stop using your phone, or pay 'casual' rates. These rates can be very expensive and generally offer poor value for money for any extended use. Sample rates from the networks include:
  1. 2degrees: Voice or video calling (49c/min), texting (20c/text), data (50c per MB)
  2. Spark: Voice calling (49c/min), texting (20c/text), data ($1/ day for 10 MB, additional data is 30c/MB)
  3. One NZ: Voice calling (49c/min), texting (20c/text) and data (50c per MB)​​

Prepay credit expires if it's not used - and you can lose your phone number

2degrees, Spark and One NZ credit all expires after 365 days, without exception.

Best Unlimited Mobile Data Plans

Our research suggests that for users that need above 8GB per month, plans with unlimited data provide better value than limited data plans with high allowances per month. In this section we present what we consider are the three best unlimited data plans available in New Zealand.

Complain about your network using the Telecommunications Dispute Resolution (TDR)

Telecommunications Dispute Resolution (TDR) deals with complaints from consumers about any product or service provided by their telecommunications company. As the customer of a New Zealand network, you have the right to make a complaint. It's a free and independent service, but you will need to follow their process to progress a complaint.

Before you complain, you'll need to raise the issue with your network directly via their complaints form or customer service team
  • Once you have done this, you must wait for a response.
  • The network will respond, but if you are unable to agree with their response and your complaint becomes deadlocked, after six weeks has passed you can raise a complaint with the TDR.

The process of complaining with TDR is outlined here. Their helpful FAQs outline what you can expect, and case studies about recent complaints about telecommunication companies in general. The process is impartial, and once a decision is made, Your network will (usually) abide by the ruling should it be in the wrong.
