You can also use yourtax.nz to share an image for any scenario you run, which makes it easy to contrast how each party's policy would treat people in different situations. Data presented neutrally can still communicate values.
Making it easy to check the policy behind any number, for whatever household you model. That was the whole point of YourTax.nz. It doesn’t say ‘low-tax good’ or ‘high-tax bad’. It shows what each party’s policy would do and links the source. It doesn’t exist in a vacuum, you bring the values.
