"At the same time, we continue to promote and support appropriate and transparent practices across our industry and seek to maintain our leadership position in terms of advice and conduct standards," he said.
AMP said that it expects to receive its individual report from the Financial Markets Authority and Reserve Bank as part of its review of the sector, after which it would "address any further actions to continue to protect the interests of our customers".
Meanwhile, AMP New Zealand's wealth management business reported operating earnings for 2018 of $57 million, broadly unchanged from the previous year.
Operating earnings were offset by lower wealth management income resulting from a decline in assets under management (AUM) margin.
AUM fell by 3 per cent to $11.6 billion, largely reflecting unfavourable investment market conditions.
AMP's KiwiSaver Scheme continued to grow with $5.1b in funds under management, a slight increase from 2017.
"Despite challenging market conditions, we continued to deliver on our commitment to provide high-quality advice and services to support our customers through the country's most extensive and diverse network of financial advisers," Vernon said.
In Australia, AMP's profit slumped to just A$28m ($29.2m) in calendar 2018, down from A$848m in 2017, as the company suffered a weaker performance in its superannuation and investments division and fallout from Hayne royal commission.
