Pre-employment drug testing in New Zealand is in place to ensure employees remain safe at all times. Companies are responsible for maintaining safety in the workplace, and a pre-employment drug test helps to reduce risk. Testing for drugs and alcohol can help ensure employees are clear-headed at all times, but policies and procedures must be very clear to ensure legal compliance is at the forefront. Other types of testing include blanket testing, post-accident/incident testing, random testing, for-cause testing, and return to work/duty and post-treatment/rehabilitation testing.
