Labour leader Chris Hipkins says he wants to revamp the tax system, after ruling out such a move just last year.
In a state of the nation speech in South Auckland, Chris Hipkins said New Zealand has one of the least diversified tax systems in the world, which he says is particularly unfair on salary earners.
The Greens have been making much the same case for some time now.
Co-leader Chlöe Swarbrick says the tax burden falls unequally on middle-of-the-road earners rather than those with the most money and big capital gains.
Swarbrick spoke to Ingrid Hipkiss.
