The owners of New Zealand's market leading practice management system vendor Medtech Global have sold the business to Australian private equity firm Advent Partners and health technology advisory firm Acclivis for an undisclosed sum, but will retain ownership of its ManageMyHealth personal health platform.

Acclivis managing director Geoff Sayer, a former managing director of Clanwilliam Health ANZ and Toniq, will become Medtech's new chief executive.
