Hi, wondering if someone might know the best option for a mobile plan.  I have relations that live in Aus (Brisbane) but also spend 4 to 5 month of the year here in NZ. They want a mobile plan that (preferably) allows them to retain the Aus number, yet make and receive local calls without paying a premium.  they would prefer not to have two numbers and forward one to the other and need data. 

As an aside, Skinny Broadband has been perfect for them, as they can simply stop credit card payments when they leave, and start up again when they get back, works a treat.... Well done skinny!!!

So back to the mobile option, any suggestions welcome.

Thanks.
