I was actually quite surprised, in my research leading up to this debate tonight, to find that the EPA actually is responsible for something in the order of 150,000 individual hazardous substances and organisms. They're not responsible for them, but they are the agency, the regulator, that is required to decide what the level of risk is or what the level of safety is in terms of having those substances available and introduced and used in New Zealand. So that's a very, very big responsibility, and the Minister mentioned the relatively small numbers of assessments and reassessments that are taking place, primarily because it's a big job to have to do it. It's an expensive, time consuming, and difficult job to do that if you're starting from scratch on a blank piece of paper and not taking into account the work that's been done in other jurisdictions.
