Former KwaZulu-Natal wicketkeeper Linda Zondi and former Gauteng all-rounder Hussein Manack have been appointed as the new selectors.
Shafiek Abrahams, who like Hudson represented the Proteas at full international level, has been retained on the panel, which is completed by the ex officio appointment of Russell Domingo as the Proteas head coach.
The new panel will serve until the next 2015 ICC World Cup to be held in Australia and New Zealand.
"The Board felt the need for a stronger independent component to the selection committee," said CSA Acting CEO Naasei Appiah.
CSA High Performance Manager Vinnie Barnes and Transformation Manager Max Jordaan will also serve on the committee in a non-voting capacity.
