The  question is not if, but rather when cannabis becomes decriminalised in New Zealand.  The  recent referendum might be a national  debate in 2020, but internationally there has been a growing move towards the  decriminalisation of cannabis for much longer. In the past decade, partial  decriminalisation of cannabis has occurred from Europe to Africa and complete  legalisation happening in Canada and Uruguay.   New Zealand’s proposed bill is therefore on the frontline of this  international discussion.  
Most of  the debate regarding the decriminalisation in New Zealand has been focused on the  abuse by and easy access minors will have to the product. The opposite argument  is the $185 million-plus tax revenue for the country.  Little narrative has focused on the impact on the  workplace or workforce.  
If  cannabis is decriminalised, employers will still be able to enforce policies to  prohibit use and possession in the workplace. These policies will be  implemented similarly to the way alcohol is monitored.
The main  purpose of these policies will be preventing the use of, possession and  distribution of cannabis in the workplace and limiting the affect recreational  usage will have on an employee's ability to work.
The onus  for testing an employee will remain on the basis set out by the courts in Engineering Printing and Manufacturing Union  and Air New Zealand. The court’s decision to limit testing to  safety-sensitive areas and reasonable suspicion will remain.  However, the consequences of testing positive  for cannabis versus other illegal substances will be the main area of change.  Presenting a positive test for any substance that contravenes the law together  with the company policy can aggravate the sanction. 
The fact  that cannabis can remain present in a test for several weeks after usage, poses  the biggest challenge. Although different tests can determine the level of  cannabis in an employee’s system it is far from an exact science. Proving the  effect/impact on the workplace and/or work relationship will come down to the  employee’s performance and/or actions rather than the results of the test. 
Creating  clear guidelines to prevent unnecessary disputes in the workplace is vital.  Such guidelines need to focus on usage, possession and testing. At EAL we are  working towards ensuring that all employers are protected for such unexpected  and unfamiliar changes and will ensure that guidelines will be available on the  Employers Toolbox, should 2020 be the year for this change.  
Some information  should the current proposed bill be passed:
    - Only  people 20 years and older can purchase and possess cannabis;
 
    - Possession  at any time is limited to 14 grams of cannabis or two plants for personal use;
 
    - Only registered retailers can sell cannabis
 
    - Only 14 grams can be gifted between persons.
