While so far the New Zealand regulators do not think a similar commission of inquiry is warranted here "the work we have initiated may test this view," the FMA and the RBNZ said.
So far, the regulators have met with 16 chief executives of New Zealand banks, including the four major Australian-owned banks and sought assurance that the issues identified in Australia were not evident in New Zealand.
They then wrote to 10 locally-incorporated New Zealand banks with major retail operations on 3 May, initiating a "review of conduct and culture by New Zealand financial services entities".
Everett said "we really challenged them to front up and confirm they didn't believe their business contain any of the misconduct we have seen in Australia and then we challenged them to explain why they reached that conclusion, what work they have done to give them that confidence," said Everett.
A total of 11 banks responded and those responses are being worked through by a joint working group of FMA and RBNZ staff. The Commerce Commission is also reviewing anything relevant to its role.
According to the FMA and the RBNZ, the banks have taken the exercise seriously, providing some very detailed responses.
Following the initial assessment, the regulators will be requesting further information and verification where necessary, he said.
The regulators have also written to 15 major life insurance companies, requesting a response by June 22.
They are anticipating putting out a report in October.
The Australian Royal Commission is expected to put out an initial report in September and a final report in February.
