There are two major Employment Court cases on drug and alcohol testing in the workplace:  NZ Amalgamated Engineering Printing and Manufacturing Union Inc v Air New Zealand Ltd (‘Air NZ”) and Maritime Union of New Zealand Inc v TLNZ Ltd (“MUNZ”).

The law is relatively clear following these cases that, in general, it is legitimate for an employer to introduce a drug and alcohol policy to the workplace, provided that the policy:

  • Is not inconsistent with an employment agreement; and
  • Is supported by the need to comply with statutory health and safety obligations; and
  • Is both lawful and reasonable; and
  • Does not impose random/suspicion-less testing on all employees; and
  • Is dynamic and has procedures in place for ongoing review as scientific advances are made (such as    less invasive means of testing); and
  • Sets out clearly what the testing protocols will be, who will carry out the testing, and the consequences of    failing a test.

Random testing
Only employees in safety-sensitive areas of work may be subject to random drug and alcohol testing.

Testing for cause
Provided there is a policy in place that allows drug and alcohol testing in the workplace, employers may test employees under the following circumstances:

  • Post accident/incident
  • Pre-employment
  • Pre-transfer to a safety-sensitive position
  • Reasonable cause to suspect impairment by the observation of symptoms (does not require actual    impairment – simply observing the employee and forming a view on reasonable grounds that they appear    to be impaired by some substance is sufficient)
