Rollover minutes only applies to the NZ included minutes of the $16 Stretch combo. Minutes in any Add ons with your combo do not roll over. Included data and texts do not rollover.
Rollover means that any unused minutes at the end of your $16 Stretch combo's 30 day cycle will rollover into your next $16 Combo's 30 day cycle provided the combo auto-renews at the end of its cycle, and is not cancelled at any stage.
If your $16 Stretch Combo fails to auto-renew at the end of its cycle for any reason, or it is cancelled at any stage, you will lose all Rollover minutes you may have accumulated (they will expire at the expiry date and time of your lapsed or cancelled $16 Stretch combo).
Until 31 January 2014, Rollover minutes also applies to the "Double Minutes" promotion, and can be used to call Australian standard landlines and mobiles from NZ.
