So, if it was a case of real increase in wages above the rate of inflation, that would be fine, but what this bill does is recognise that inflation is a major driver of how people get into a higher tax bracket. And so what the bill requires is for the Government, every three years, to look at what has happened with inflation, and the inflation rate it uses is the Consumers Price Index. There's a whole range of different inflation rates and measures—Producer Price Index. But, for the purposes of this bill, it uses the Consumers Price Index and it says that every three years there is a reset to make sure that people, effectively, if there's been a substantial amount of inflation, will be no worse off as a result of that inflation. That means that they will still be paying the equivalent amount of tax or the tax rate that would have applied if there hadn't been inflation. So it is a very important one about making sure that New Zealand families and individuals are not worse off as a result of inflation.
