Lot of Kiwi taxpayers use Kiwibank, & those who don't might start to consider it. I think overall its a nett positive benefit for the country.
The big 4 Australian banks shovel around $5.5 billion in NPAT out of the NZ economy while closing branches, reducing customer services & shunning the rural sector.
Wonder if the govt will switch its banking from Australian owned Westpac to Kiwibank?
