Free calls to New Zealand mobiles

How can I make totally free calls to New Zealand mobiles using a VOIP service?

Voip rules in New Zealand are quite flexible. I mean yes you can use Voip services to make cheap and freephone calls. There are actually many voip providers offering free calls to New Zealand landlines phones but a very few offers free calls to New Zealand mobile phone.

Webcalldirect and other betamax services offer free calls to New Zealand landlines phones. However they charged about 17 cents per minute while calling landline phones.

I guess one way would be to ask the one you want to call in New Zealand to use Voip software in his mobile. He can either use Fring or any other SIP application and using Wi-fi hotspots you can talk for free. Many other mobile voip services can also be used.

If you dont want to use Voip in mobile then you have to ook for some voip trial offer to make free calls to New Zealand mobile phones.
