Taite said allowing more Australian advisers to operate in New Zealand might take the pressure off having qualified financial entities such as banks give advice.
It would also be positive for Kiwi advisers whose clients moved back and forth across the Tasman for work.
"It's part of closer economic relations. We see a single market or a common market going forward. We see this as being a positive," Taite said.
The deal allows Australian qualified advisers to apply to be an authorised financial adviser based on their existing Australian qualifications.
An FMA spokesman said all advisers must still meet good-character tests, which would take into consideration any disciplinary action or criminal convictions in their home country.
"The arrangements ... only provide an exemption from the educational qualifications."
All financial advisers in New Zealand had to become licensed from July last year.
