Former JP Morgan head of product for custody and fund services David Braga will take on the new role in mid-May.
Mr Braga, who is also chairman of the Australian Custodial Services Association, will take over from acting head of BNP Paribas Securities Services Ian Perkins.
Mr Perkins will move into the role of head of client development.
Commenting on the new role, Mr Braga said he was "delighted to join BNP Paribas Securities Services' successful team".
"I am impressed with their global capabilities, client focus and commitment to the Australian and New Zealand markets," he said.
"This strength was recently demonstrated when BNP Paribas Securities Services won mandates from Twusuper, Australian Unity and Certitude – demonstrating the strength of its full-service proposition, which includes custody as well as front, middle and back office services for asset owners and managers in Australasia," Mr Braga said.
