CHRIS PENK (National—Kaipara ki Mahurangi): Thank you very much, Madam Chair. Just to continue on that theme, of course, a person to be working for the nominal additional dollar would—or at least the additional dollar, to be fair—have to expend a certain amount of effort and energy and cost, even, to get to work and so on. Actually, I have a sort of related point, but it relates to the amount of the value of the tax credit versus the cost of calculating the jolly thing, because if we think about the amount of time and energy and perhaps even dollars it would take to make the calculation, to the Minister and Madam Chair, it's actually a relatively small amount when one thinks about calculating the complicated regime where we've got several different time frames, several different amounts, and the extent of the credit would actually be relatively modest.
