Non-profit groups plan to approach the state capture inquiry to find out who the spies were that infiltrated their organisations.
They include Greenpeace Africa, the Right2Know campaign, Amabhungane and the Abahlali Basemjondolo shack dwellers movement.
State Security Agency operatives had testified the NPOs had been infiltrated.
The groups say they still don’t know who the agents are and urgently want help.
