It's a publicly funded system. I think it's been mentioned before that most people would access it through going to a doctor to pick up a prescription, then going to a chemist, a local pharmacist, and picking up medicine that way. Essentially the way the system works is that as soon as the scrip is filled, the company gets a cheque from Pharmac for those medicines. That is how the system works.
