Hon JULIE ANNE GENTER (Green): Tēnā koe, Madam Speaker. Tēnā koutou e te Whare. I just want to start by acknowledging that a lot of effort went into the design and drafting of this legislation to ensure that it could meet both the concerns that have been raised about the potential impact that impairing substances were having on our deaths and serious injuries on our roads, and the fact that there's actually quite a bit of uncertainty still with the tests as they are, and about their ability to establish impairment alone. So a lot of work has gone into this legislation as it's proposed to ensure that there would be minimisation of false positives and to ensure that there is as good a relationship as can be established between a given saliva level and impairment. Of course, there's no ability through the saliva tests alone for anyone to get a criminal conviction. This was really important because the saliva tests cannot provide the evidential standard that would be needed to give someone a criminal conviction for driving impaired.
