Its a colossal industry. Banks in NZ make by far the biggest profits of any business sector. Trouble is most of that profit heads west across the Tasman to the banks' Australian owners, the same owners who are currently being publicly vilified, even accused of criminal behaviour in the course of an unprecedented Royal Commission. "There's nothing to worry about in New Zealand", the banks want us to believe. But thats not what current bank employees here have been telling SUNDAY.
