The only way to get BIS is to subscribe to it through a cell carrier. Since none in New Zealand support it, there's really no other easy way to get it.
If you ever visit another country, you can aquire a SIM card from another carrier and use it in your phone when you're in New Zealand but be prepared to pay a LOT of money to use it. Not worth it, really, but it's an option if you're desperate enough to try it.
Sorry I didn't have better news for you.
