Mabizela joined AmaZulu on a short-term deal in January after being dismissed by Mpumalanga Black Aces following a fall-out with management.
The 33-year-old went on to impress for Usuthu despite their ill-fated campaign, which ended in relegation to the National First Division.
"We are busy working with him at the moment and working on opportunities," Makaab tells KickOff.com.
"What I can tell you is that we are busy talking to a number of clubs and we are obviously waiting for feedback from those clubs."
Makaab further revealed AmaZulu made no offer to extend Mabizela's stay in Durban.
"No, there wasn't such talk," he says.
