if not then they may not have a c-tick and may not be leagal to use in New Zealand.
If they are then you will need to contact us so as to revise the C-Tick details and ensure that they have confirmity.
Other than that they are great cards and we have been setting them for ages. You have to be carefull with the clipon antenna as there have been a few people whoi have snapped off the connector of them.
