Importing here is useless, it literally costs thousands of dollars for the QT, paperwork, testing and all that because nz needs to be "clean and green" So no one really does it since it costs way more then its worth.
I think there a few with licenses but in order to make a shipment worth it we would need a whole bunch of fish imported otherwise its not worth the cost, and there aren't that many betta fans in nz.
We have only just received dragons into nz which go for $50. And te worst part of it is that the best LFS and breeders are in the north island and half of them are too scared to ship down to chch where I am and if they do then its another $40 for shipping...
Sorry just my little rant.
But yeah...importing into nz is virtually impossible unless you are absolutely loaded with cash... I may have to start up a sheep breeding business to raise money for the cause haha
