Hon JAMES SHAW (Minister of Climate Change): So when it comes to the confidential reserve price, the analogy that I would use is selling your house at auction, which is a system that New Zealanders are very familiar with. Usually when you sell your house at auction, you don't tell the market what your minimum price would be. You don't say, "I will only sell this property for $500,000.", because then bids will tend towards $500,000, and, obviously, you'd like to sell it for more than that. So the question that you raised about the price floor of $20, which is public, and currently the $35 fixed price option, which is going to be replaced by the cost containment reserve trigger—those, really, are mechanisms to allow the economy to adjust over a period of time.
