In overall customer satisfaction, NAB beat its big four rivals with a score of 7.1. Westpac was second with 6.9, followed by Commonwealth and ANZ, which both scored 6.8.
Smaller players again dominated in the overall satisfaction stakes, with Greater Building Society topping the list on 9.2 points. ING Direct was named best bank, most trusted bank and most recommended bank, while ME Bank was recognised as offering the best customer service.
Mozo managing director Rohan Gamble said competition returned to the banking sector in 2011, illustrated by a step-up in marketing.
"While these stunts certainly grabbed the headlines, customer satisfaction is driven by actions, not marketing," he said.
"The NAB's axing of penalty fees, ING Direct's consistently competitive interest rates and the Greater's commitment to people before profits have made them the big winners in customer satisfaction."
