Controlled Substance Licence (CSL)

CSL is required in New Zealand if you need to possess high-risk hazardous substances for your work.

Obtaining a Controlled Substance Licence (CSL) is a regulatory requirement for professionals in New Zealand who intend to use, handle or store specific hazardous substances, particularly within pest control and other regulated industries.

CSLs are mandated by the Environmental Protection Authority (EPA) under the Hazardous Substances and New Organisms (HSNO) Act 1996 and issued by WorkSafe NZ. Adroit Solutions provides comprehensive training and guidance to help you navigate the CSL initial pathway, understand evidence requirements.

What is a Controlled Substance Licence (CSL)?

A Controlled Substance Licence is a legal requirement for individuals who handle, use, or store certain hazardous substances that pose a significant risk to health, safety, or the environment. These substances are typically classified under the Hazardous Substances and New Organisms Act 1996 (HSNO Act) and regulated by the Environmental Protection Authority (EPA) and WorkSafe NZ. The CSL demonstrates that you possess the competence and knowledge to manage these substances safely and responsibly, minimising risks to yourself, others, and the unique New Zealand environment.

Who Needs a Controlled Substance Licence?

A CSL is required for people who use certain controlled hazardous substances for pest control. The requirement applies to individuals who are responsible for the use, handling, or application of these substances in the course of their work.

A CSL may be required where you:

  • Use controlled substances for pest control operations.
  • Apply or manage certain highly hazardous vertebrate toxic agents (VTAs).
  • Are responsible for the safe handling, storage, or application of controlled substances.
  • Need to demonstrate the required level of knowledge, competence, and practical experience to legally use controlled substances.

If you are unsure whether your activities require a CSL, our team can provide clarity and guide you towards the correct training pathway. It is crucial to comply with all regulatory requirements to avoid penalties and ensure safe operational practices.
