When you consider the scale of this revenue, this tiny bug versus the enormous debt, you know very quickly that this has absolutely nothing to do, Jamie Strange, with paying down New Zealand's debt or creating revenue. That's a complete furphy of an argument. Grant Robertson may have hoodwinked you in caucus about that one, but there's no substance to back it up when you look at the actual numbers. So then you turn to the second purpose, and I also want to point out on that revenue point that the advice in these papers is very clear, that officials are very concerned about what those revenue numbers will actually be, given all the behavioural issues that may be occurring.
