What type of workplace drug testing should I implement?
Depending on your industry, you will have different requirements for your employee drug testing programme. We would recommend the following:

Random Drug Testing – this involves testing all of your employees on a random day, or a randomly selected group of employees.

Pre-Employment Drug Testing – this involves testing all potential employees before employment. This greatly decreased the chances of hiring someone who is currently a drug or alcohol user.

Reasonable Cause Drug Testing – this involves testing employees who you have reasonable suspicion of being unfit for duties. This protects the safety of your workplace.

Post-Incident Drug Testing – this involves testing employees who have been involved in an accident or near-miss to help determine if drug or alcohol use was a factor.

Return to Work Drug Testing – this involves testing employees before they can return to work after a positive test or as periodical follow-up to ensure that they have stopped abusing drugs or alcohol.

Pre-Promotion Drug Testing – this involves testing employees before promoting them to ensure that you are not promoting someone who may have an alcohol or drug problem.

Is there a standard around drug and alcohol testing in workplace?
Yes, for urine drug testing this is AS/NZS 4308:2008. The alcohol breath testing device standard is AS 3547:2000. These can be downloaded from the Standards New Zealand ( At this stage, New Zealand does not have a standard for saliva drug testing.
What is the difference between saliva and urine testing?
The main difference is drug detection times. Urine drug testing picks up a much longer window of detection. This is especially useful for pre-employment. Urine drug testing is the most accurate and cost effective way to ensure you have a safe working environment.

Saliva testing shows a much shorter detection time on drugs, particularly cannabis. Depending on drug usage, saliva may only detect drug use within the past 2-4 hours. Saliva drug testing is most useful for picking up recent use and impairment.

What are adulterants?
Adulterants are additives that are used to try to cheat a drug test if there are drugs in a person’s system. If the temperature strip on the urine drug cup is read, along with the adulterant panel before results are interpreted, you can almost always pick up attempted adulteration.
What is the temperature strip on the urine drug cup for?
The temperature strip ensures that the urine is at body temperature, and has been provided by your specified donor. This is the first thing you should check after you have taken a urine sample.
What are cut-off levels?
The cut-off level defines the test as a positive (non-negative) or a negative. In New Zealand, the cut-off drug and alcohol levels are determined by AS/NZS4308:2008 Standard. Concentrations above the cut-off level are positive and concentrations below the level are negative. The cut-off level ensures there is no risk of a false positive from accidental contamination or exposure to drugs.
