Zulu, who was released by Mamelodi Sundowns in January following a string of off the field incidents, is currently training with the Students.
Hunt confirmed that the 25-year-old was training with the Clever Boys to rebuild his career and stay fit while he searches for another team.
“He’s just asked to come and train. I’m not going to make a decision now about that. So, we will see,” said Hunt.
Wits currently have Sifiso Hlanti and Lehlohonolo Nonyane at left-back and Zulu would be the third choice left-back if he is signed.
