Hon GRANT ROBERTSON (Minister of Finance): I'm at risk of repeating myself here, but this is about making sure we have the best-practice, fit for purpose, modern form of governance for the bank. In 1989, decisions were made about having a single decision maker on virtually everything that the bank did. The member is correct in saying that other jurisdictions around the world looked at what we did and took many aspects of what we did, but you will struggle hard now to find anywhere in the world where a central bank operates entirely on that single decision maker model. So it's a matter of the fact that in 30 years, the way we do this—the way we govern what we do—has changed. We've had significant experience in New Zealand through the Crown entities on how best to see a board like this run, and that's what we'll cover when we move into Part 2 of the bill.
