The effects of the 2009 global financial crisis are still being felt, judging by the number of complaints being laid about banks, banking ombudsman Deborah Battell says.
Battell said complaints and inquiries made under the banking ombudsman scheme are running at historically high levels, but the number of disputes requiring investigation is down.
The main issues during the year were related to hardship, mortgage and loan defaults and investment, she said in a statement to coincide with the release of the scheme's 2010/11 annual report.
There was a big jump in complaints about current accounts - half of which were related to claims of negligence, bad administration or errors.
The workload in the previous year was dominated by complaints about the freezing of funds by ING NZ and ANZ National Bank.
