Cannabis is legal for medicinal use in New Zealand with a prescription but is still considered a controlled substance. Depending on its form, cannabis is either a Class C or Class B substance under the Misuse of Drugs Act. Cannabis resin (commonly known as hashish) and cannabis oil (commonly known as hash oil) are Class B. All other cannabis products, including cannabis seeds are Class C. This means that it is illegal to possess these drugs if you do not have a medical prescription. It is also illegal to buy, sell, grow, or import THC and CBD cannabis products in New Zealand. Even if you have a prescription for a cannabis product, you cannot give this to other people.
