Some of the media reports from New Zealand imply that the National lead coalition government will increase GST to pay for a cut mostly to the top income tax rate. In my book that would be daft. New Zealand already has a higher GST than Australia and New Zealand does not have the equivalent of Australias tax free threshold. For a young person starting out the tax system in Australia seems comparatively better in relative terms. Little wonder so many young Kiwis try their luck in Australia.
The National Party youtube message seems to imply a more general cut to income taxes. However raising one tax to cut another is really just shuffling deck chairs. I suppose we will find out the reality in the fullness of time.
