SIMEON BROWN (National—Pakuranga): Thank you, Madam Chair, for the opportunity to take a call in the committee stage on the Drug and Substance Checking Legislation Bill. I've got a couple of questions in regards to how this bill is going to work. My first question is around how a young person who's attending some festival somewhere, when they turn up to the festival and someone's there saying, "I'm going to test your drugs", how to know that they have been certified under clause 10, new section 35DA. The ministry has to have a website which lists the people who have been certified, but there's no information required—from what I can see—for the service provider to actually put it in front of that young person their certification, the fact that they have been certified by the Director-General of Health. How are they going to know that this person has been given the lawful authority to do this drug testing and that they are doing it in accordance with the law and therefore meeting the standards and the conditions imposed upon them by the Director-General of Health?
