The review will be chaired by capital markets veteran Martin Stearne.
Matt Goodson, managing director at Salt Funds, said it was a review was a worthy exercise to go through, particularly given the low proportion of the market relative to GDP.
"Going through the reasons for that, and to find out what, if anything, can be done to change that, would certainly be worthwhile," he said.
"Relative tax on different asset classes could be one thing, and the lack of a major bank listed bank here is probably another," he said.
Results of the review are due out in the third quarter of this year.
