South Africa Tourism confirmed Abberley left last month but would not comment on the reason for her departure.
Abberley joined South African Tourism in 2008 as business tourism manager with a remit to boost business tourism visitors to the country. In February 2012, South Africa Tourism launched the South Africa National Convention Bureau (SANCB), and Abberley's role changed to manager of meetings and convention sales.
Last January, SANCB announced it had appointed Gaining Edge as its sales representative company for the European and Asian markets.
Abberley joined South African Tourism from Visit London, and prior to that she spent five years as an events manager at agency George P Johnson.
