The case was postponed until January 20 to confirm their details, said spokesman Captain Paul Ramaloko.
The two Nigerian men, aged 41 and 33, and a Zimbabwean woman, 23, were arrested on Friday, Ramaloko said.
The Hawks recovered crystal meth, cocaine and CAT with a combined estimated street value of R1.2 million.
The three allegedly used the upmarket suburb to distribute the drugs.
Gauteng head of the Hawks Maj-Gen Shadrack Sibiya said at the time: “The team will not rest until a drug laboratory linked to this distributing facility is detected”.
