But also there is commentary that National talked about around the efficiency principle. The chair of the Finance and Expenditure Committee, Dr Duncan Webb, who did a great job chairing, I must say, touched on it briefly around the efficiency principle and around that, basically, it's such a subject of principle based on this particular proposed bill. So what this side of the House has suggested is that you don't include it. We had a really good debate in the select committee around why you wouldn't include it. And so it came down to, for us, that when, in 1989, the Reserve Bank bill was going through the House, there was nothing in Hansard on the intended meaning of "efficiency", but that's because back in the 1980s, this particular Act was really narrow. It was on the financial stability; the role was narrower. It was limited to the registration of banks. That's why we have this bill coming to the House—because we've needed to extend it. It's now doing a prudential role around insurance. It still has the bank regulatory powers. But we've seen that in the last 30 years it needed to be updated.
