Dr LIZ CRAIG (Labour): Thank you, Madam Speaker, and I'd just like to thank Matt Doocey for the opportunity to spend the evening talking about workplace health and safety, which is a really important issue. Before I go into the specifics of the bill, what I want to do, though, is just talk about the broader context in terms of workplace drug-testing and what it actually aims to achieve, and then think about whether this bill actually takes us further in that direction. If you go to Employment New Zealand's website and you type in "drug testing", you come up with their "Drugs, alcohol and work" page, and one of the key points it emphasises there is that, under law, both employers and employees have a duty to ensure that their workplace is safe. Then they go on to talk about using drugs and alcohol can lead to employee impairment at work, and they talk about some of the effects of impairment: poor concentration, carelessness, risk-taking behaviour, and errors in judgment. Then they also talk about how alcohol and drug use not only affects work performance and productivity, but you end up with higher rates of injury, fatalities, and absenteeism. So the key function of testing for drugs at work is to make sure that we've got a safe workplace, but it comes down to the impairment factor on that and, basically, the fact that that impairment then can go on and compromise the safety of the employee themselves, their fellow workers, and members of the general public.
