Top banned substances in NZ 2023
Top substances for sanctions
Back in 2019 we published a blog post that would become one of the most-viewed on our website. It was a list of some of the top substances of concern that are banned in sport and responsible for athlete sanctions here in NZ.
We’ve updated and expanded that post for 2023 and beyond, adding more substances of concern and the health consequences you risk if you use them.
Remember: If you play sport at any level, the Sports Anti-Doping Rules apply to you. If you’re found to use, possess, buy or traffic these (or any other) banned substances, then you could be subject to an anti-doping sanction, including a ban from all sport.
Before you take any substance, check if it's banned in sport.
