Rt Hon JACINDA ARDERN: No, not at all. I simply point out that where waste-water testing occurred is not a political decision; it's a decision made by our public health advisers and by ESR. As you'll see, where we have waste-water testing—and, as I understand it, it is quite a difficult and onerous exercise, as it's been explained to me—but where we might have concern, then you might go in and start doing additional waste-water testing on much smaller areas. So when we got Warkworth, we then had a breakdown of over 20 waste-water samples that were taken across different sites in Northland to add additional information. But sometimes those single sites then point you in the direction of subsites that you should then go and test within. So those are decisions ESR and Health make.
