Consumer advocates say a muscled up Kiwibank is no silver bullet to fix the country's banking sector.
A draft Commerce Commission report has found a lack of competition in the personal banking sector and says New Zealand-owned Kiwibank is too small to disrupt the market.
It says there's a two-tier market in which the big four Australian-owned banks have the major share, with smaller operators offering no threat to that dominance.
Monopoly Watch director Tex Edwards, Simplicity's Sam Stubbs, and Consumer NZ chief executive Jon Duffy spoke to Corin Dann.
