Wow, that's amazing for NZ to fund it but not Aussie, PHARMAC is very good at keeping drug prices down in NZ and proof to get funding due to being better than anything currently listed is difficult vs what I have seen in Aussie. But that was over 15 years ago now. A basic example was Crestor when it came out, list in Aussie, private in NZ. Cheeky part was it cost significanlty less in NZ at the time to purchase wholesale as well.
Yeah after 6 months you can apply for one, there is also the reciprocal health agreement. Just show you NZ passport at Dr or Hospital.
Also might be the opportunity to do a telehealth consult with your doctor back in NZ, have script sent to pharmacy there, call them and organise it to be posted over?
