"Over the past 12 months we noted an improvement in the average cost of new funding as some of the turbulence in the global markets abated," Chapman said. "However uncertainty remains around the recovery of Europe's economies as well as the markets' reaction over the Federal Reserve's intentions around the unwinding of its quantitative easing programme. Both factors may put pressure on the financial markets and the consequent cost of funding over the next few years."
Still, Chapman said she was confident ASB would continue to deliver profitable growth.
ASB's Wealth and Insurance business improved as investment in its KiwiSaver scheme grew 29 per cent to $2.9 billion.
The New Zealand business has been managing costs relative to revenue growth and focusing on increasing productivity, resulting in a reduction of operating expenses as a percentage of total income to 41.1 per cent from 42.6 per cent, the company said.
Customer deposits increased 6 per cent to $41.3 billion, while loans to customers rose 8.9 per cent to $57.7 billion.
ASB set aside $56 million for bad debts, up 19 per cent on the year earlier. The company said the increase was expected as provisioning returned to more normal levels from a low in the prior period.
