The young mother is alleged to have poisoned her four children aged between 11 months and eight years on December 27.
The bodies of the children were believed to have been kept in the back room that Maditla and her children rented until December 30, when she reportedly told a relative to go and check her home.
Police said the corpses had already begun to decompose and had been wrapped in blankets.
Ethan, Shaniqua, Blessing and Minenhle were buried last week in a service at which their mother was not present.
Brig Leonard Hlathi had told TimesLIVE that neither Maditla nor her family had made any application for her to be released for the funerals.
Hlathi said that had Maditla made such an application, several aspects, including her own safety, would have had to be considered.
Following the gruesome discovery, a drowsy Maditla had handed herself over to police and was hospitalised shortly thereafter.
She was discharged earlier this month.
