I'd like to move on to Supplementary Order Paper 15, which tables an amendment to the Climate Change Response (Auction Price) Amendment Bill, and which address the real risk and, as yet, the unaddressed risk that should an auction with a confidential reserve price fail to clear, bidders who bid in good faith and who submit bids above the confidential reserve price will find that they're not able to take New Zealand Units away from the primary auction. It's been offered that those bidders could then go to the secondary market and secure the units that they need. It's also been suggested that they've had a long time to prepare for this. It's been suggested that there is a large bank of New Zealand Units or carbon credits out there.
