The second Supplementary Order Paper in the name of the Hon Julie Anne Genter relates to a review—an independent review, in fact—of the efficacy and how this legislation would be working. There are a number of specific considerations that have been requested to be included in that review, including the impact of the amendments; importantly, the reliability of oral fluid tests and blood tests in measuring a person's impairment; whether appropriate thresholds and impairment levels have been set; and whether the amendments have been appropriately implemented by the New Zealand Police and by other relevant entities. Of course, this remains of fundamental importance when we're talking about drug law, which is so often empowered by moral panic, but, of course, noting that there is shared consensus within this House of the need to seriously arrest and address this issue on our roads. There is also a call for whether the amendments have had a disproportionate impact on Māori and Pasifika; the extent to which, if it can be assessed, the number of people driving while impaired by drugs has changed since the amendment came to force—which, of course we would hope, if it were effective, it will have—also whether further amendments should be considered; whether any of the amendments should be repealed; or if there are any other matters that the Minister considers to be relevant for that independent reviewer. That review would be required to be completed and presented to the House within 12 months of commencing.
