As members of the committee will have heard from the former Associate Minister of Transport and the Green's transport spokesperson, the Hon Julie Anne Genter, there is a lot to weigh up when we come to building new infrastructure for how we go about ensuring that we have harm reduction, particularly pertaining to harm reduction on our roads. We fundamentally agree that driving impaired by drugs is a serious hazard to safety on our roads, and we agree with the objective of the bill, which, of course, is to try and deter people from driving while impaired. But we remain concerned with a key issue as raised by submitters, particularly during that select committee phase that the Minister referred to, that there is currently a lack of evidence that the approach may result in a reduction in impaired driving. There are also concerns that persist that it is difficult to establish a relationship between a given level of a drug in oral fluid or in blood with a specific level of impairment and that this could harm any intended deterrent effect. There are also substantial concerns, as floated in the Transport and Infrastructure Committee, that this regime could disproportionately and harmfully affect Māori and Pasifika.
