So they ask the legitimate question: how are we going to pay for all this? The worry that many New Zealanders have is that this is a Government, with $20 billion in Grant Robertson's kitty, that will spend whatever it takes to try and keep their polling up till 19 September, then on 20 September the smiles will drop from their faces and New Zealanders will be presented with the bill, and the bill is higher taxes next year if they were lucky enough to win the election. So New Zealanders have got a stark choice: do they want those higher taxes or not? And they'll be asking themselves that over the next little while.
