Submitters also suggested that the likes of American Express, as I've mentioned, and other card schemes should be directly regulated by the bill, in addition to the immediate price regulation being applied to Visa and Mastercard. I do want to say, so that this is on record for the House, that American Express is absolutely in scope of regulation under the new regime, although it hasn't been chosen to be designated straight away. So the Commerce Commission can choose to designate them in due course. But my focus in having a price path, effectively, for Mastercard and Visa payments to start is because that brings about the greatest immediate benefit for merchants and consumers. American Express, as we know, has a relatively small share of the market—their model doesn't involve interchange fees, and they're also constrained by competing with Visa and Mastercard in what they can charge—and, of course, if we regulate their fees, that will have a knock-on effect to the model for American Express.
