Now, to do that, we had to change the law, because the law didn't allow clearly—it was arguable whether the commissioner was entitled to gather that information for policy purposes as opposed to tax administration purposes, and the risk that Revenue faces, when they ask for that sort of information, is that taxpayers can say, "I'm paying all my taxes; this is a fishing exercise. You're not entitled to this for policy purposes. Go away." We thought that wasn't right to have that gap in information and, in order to do that, we had to change the legislation. We actually did that very quickly in the first Budget following the election. We passed it under urgency. Some parties criticised us using urgency. If we hadn't done that, we wouldn't be able to do this information gathering during this triennium, which we thought should be within the power of Government to do. So we passed that amending legislation, which then enabled the revenue department to gather that information. We set up the rules based on their advice as to how we do it. We've got an advisory group as to how that information should be gathered and analysed, which includes public and private sector experts in tax matters. That information is currently being gathered and, as soon as it is gathered, it will be analysed and, as soon as it is analysed, that information will be released publicly.
