The Government is proposing to release 4.75 million units at a time. Because the secondary market is constrained, if the Government's primary auction fails, there could be a rush to the secondary market by those businesses which have obligations, because what the emissions trading scheme does and the zero carbon Act does is it puts obligations on businesses that emit carbon as part of their business to have New Zealand Units—carbon credits—and then to hand them in. That's their obligation: to pay for their emissions, and then to hand those certificates over to the Government at the end of the financial year. If they can't get the units that they need, then there's a risk that they could have to scramble to the secondary market. There could be price spikes, or there simply won't be enough units available for a business to meet its obligations. You might say, "Well, this is something that they should plan for." Well, they have been planning for it. They have been planning since the original bill was passed, and now what we see is this amendment bill—the auction price amendment bill—being brought to the House under urgency to add in this new control, this confidential reserve price.
