The Banking Ombudsman Scheme received 16 per cent more cases in the past financial year, refuting expectations that the use of the scheme would decrease as consequences of the global financial crisis eased.
Banking Ombudsman Deborah Battell said while global financial crisis (GFC) related complaints were down, contact with the Banking Ombudsman remained high due to public interest in legislative changes including anti-money laundering legislation, bank fees litigation and the ANZ/National bank merger.
Complaints from small businesses also increased - making up just over one in 10 complaints, Battell said.
"While the GFC is no longer affecting personal banking customers, it appears small business are still feeling its lag effect."
The Banking Ombudsman Scheme's Annual Report for 2012/13 showed nearly a third of dispute cases in the past financial year resulted in a favourable outcome for customers, either partially or in full.
