As Mr Bayly indicated in his speech, it's highly unlikely that this will actually raise more than a very small amount of revenue. If one looks at the impact assessment that has been tabled with this bill, the IRD agrees. It says that "the estimates are highly uncertain." They arise because they "are sensitive to assumptions about how … people change their behaviour … There is significant uncertainty in these assumptions". So not only does it not feel fair to me, it's not going to make a blind bit of difference, particularly in the context of the massive, massive spending that the Government is doing. It should be cutting taxes, not increasing them, and the process has been appalling.
