DAMIEN SMITH: —in backing New Zealanders to improve their own lives, Mr Webb. For too long, the tax system has been used for political vote-buying by parties opposite. The current tax system is one of the central reasons that productivity growth is weak and living standards are lower than they should be, and we should expect better. There are some positive steps, though, in this bill: the trans-Tasman retirement savings arrangement, the Mycoplasma bovis, and farmers bill, but we have also had some negative impacts, as mentioned earlier, around global warming.
