When we canvassed with submitters and with officials the nature of testing, the oral fluid devices will initially be able to test for six particular drugs. Of course, we're familiar with THC. We hear more and more about methamphetamine in use, particularly in Auckland and our surrounding suburbs. Benzodiazepines is also another one. MDMA—which is ecstasy—opiates, and cocaine. So what we need to do is to ensure that we are able to test adequately and ensure that the right tests and the right approach by New Zealand police is in place in this particular area.
