So just thinking, though: who can test? Is it just something that any employer can request of the employee—and the situation there is no. Generally, an employer can only really ask an employee to have alcohol or drug testing if it's a condition of their appointment and if it's in the employment agreement or if it's a workplace policy. So, basically, Employment New Zealand recommends that employers thinking about drug testing their employees seek legal advice because, basically, what you've got to weigh up are the risks and benefits versus the privacy and invasion of privacy for individual employees. Basically, if they're thinking about it, why they might be doing it is to protect the safety of employees or the general public—for example, if the employee works in a safety-sensitive area or if their work directly impacts the safety of others, other colleagues or members of the public—and you've also got to balance that requirement about safety versus not creating unreasonable intrusion into the privacy of employees.
