You would need to graduate from the college of veterinary medicine for New Zealand, or possibly from one of the seven colleges of veterinary medicine in Australia (depending upon where you can be accepted at and afford to study at). You would also likely need to pass a standardized licensing test, be licensed to handle controlled drugs (most anesthetics and euthanasia agents are regulated at the national level), and be certified to issue various health certificates like rabies vaccination and travel papers.
you have to take a test on veterinarian medicines
A DVM or Doctor of Veterinary Medicene.
a degree
A criminologist who decided to go to veterinary school and get the proper training and licensing could become a veterinarian. However, if you were envisioning some kind of dialogue like:C: "Hi, I'd like to become a veterinarian."State: "Okay, we'll need to get a copy of your transcript and diploma from veterinary school, and you'll have to pass the licensing exam, and ..."C: "No, you don't understand. I'm a criminologist."State: "Oh, sorry, here's your license. Can you take a look at my dog?"That's just not how it works.
you need at least 8 years of training to become certified

More or less, any kind you want. Veterinary medicine is a broad-based comparative science field, and there are veterinarians that do everything from vaccinate cats and dogs to drug testing racehorses to performing experiments in space (there has been one veterinarian who was also an astronaut).
Any kind they can afford.
