01
Core Event – How the Medical Defence Works
Under New Zealand’s roadside drug-testing regime, a driver may invoke a medical defence only if they test positive for a drug that can be shown to have been lawfully prescribed. Police note that the driver must provide documentation from a medical clinic confirming the prescription. Since the programme was expanded nationwide in July, four drivers have successfully used this defence to avoid infringement notices, while one recent application was rejected, resulting in a penalty for failing or refusing the test.
02
Official Statements & Responses
Police Minister Mark Mitchell emphasized that the testing system is not intended to target legitimate medical use and expressed confidence that the medical-defence process is functioning as designed. The police framework reinforces the requirement for a prescription, supporting documentation, and a letter from the prescribing clinic.
03
Criticism & Opposition
Waseem Alzaher, chief executive of Cannabis Clinic, voiced disappointment over the low number of medical defences lodged. He argued that the shortfall is not due to a lack of awareness but reflects a persistent illegal-use culture and stigma that deter people from transitioning to the medical model. Alzaher urged patients to obtain proper prescriptions, keep thorough records, and adjust usage timing to avoid impairment while driving.

Verbatim Quotes
- “I think it comes down to the fact that there still are a lot of Kiwis who are using cannabis illegally, that have not transitioned to the medical model.” — Waseem Alzaher, cannabis clinic chief
- “For example, will my doctor judge me? Will they prescribe for me what I want? Will they understand me? Am I safe? Will they get what I’m doing? Or will they label me a drug seeker?” — Waseem Alzaher, cannabis clinic chief
- “Use your cannabis in the evening so that you’re not impaired. If you’re feeling impaired, don’t drive.” — Police Minister Mark Mitchell
