Prohibited substances

The Prohibited List

The Prohibited List is published by the World Anti-Doping Agency (WADA) and details all substances and methods which are prohibited or banned in sport.  It is updated every year on January 1.

A substance or method may be included on the list if it meets any two of the following criteria:

  • it has the potential to enhance sporting performance
  • it presents an actual or potential health risk to the athlete
  • it violates the spirit of sport.

Check a medication.

The information below gives you a basic summary of the kinds of substances and methods that are banned in sport, but we also advise you to check the full WADA 2021 Prohibited List (PDF).


Permitted Prohibited at all times – Requires a TUE
All antibiotics available in New Zealand are permitted in sport Probenecid is commonly prescribed with antibiotics. It is prohibited without a TUE


If you need to take medication to keep your asthma under control, you need to know which asthma medications are allowed in sport and which are not.

If you use asthma inhalers and you are tested, be aware that maximum thresholds exist and overuse of some inhalers could return a positive drug test (see below).  Follow the directions on the prescription label of your inhaler and talk with your medical professional if you need to use your inhaler frequently.

Please contact DFSNZ if you need more clarification.
