In any case, that was an important period in New Zealand history, because, by halving the top tax rate, the amount of revenue collected off the top tax rate actually increased. The reason for that is that when Governments have a wide range of rates of tax, it creates more and more opportunities for people to change the incidence of their tax—to change how they pay it, what entity pays it, and in what time period. If they can shift some of their income into another time period, then they can reduce the amount of income tax paid. Now, to some extent, that's an inevitable result of any tax system, but the more complex our taxation system gets, the more difficult it is for Government to collect tax and the more difficult it is for citizens to comply with tax law. The net result is that New Zealanders spend more time on administering tax, from the IRD side, and complying with tax, from the citizens' or the taxpayers' side. That leaves less time to do the kinds of things that make life worthwhile. Nobody, as far as I'm aware, actually enjoys tax compliance or, even in the case of Inland Revenue staff, tax administration.
