Finance Minister Bill English says bank customers should shop around for lower interest rates after one of his backbench MPs said banks were "gouging" customers with high overdraft rates.
Appearing before Parliament's finance and expenditure committee Mr English faced a questions from National's MP for Wairarapa, John Hayes, about the effect of high interest rates on the local economy.
Mr Hayes said his own electorate would benefit from greater consumption or spending which would result in more jobs, however high interest rates were hampering that.
"It seems to me in my electorate banks are gouging particularly on their overdraft rates charging about 2 per cent more than they need to."
