Johannesburg - More human remains have been found in the vicinity of the ill-fated Italtile aircraft, a Western Cape Forensic Pathology Service spokesperson said on Tuesday.
"The remains have not yet been identified as belonging to the missing persons. The search will continue," said Zolani Zenzile.
He said seven of those who died in the crash had been identified so far.
The PC-12 aircraft was carrying Italtile employees and business partners when it crashed last week. Its CEO Gianpaolo Ravazzotti was killed.
The plane was travelling from Queenstown to Plettenberg Bay when it crashed while trying to land in heavy fog near the Robberg Nature Reserve.
Zenzile said the search could be called off by Wednesday.
The SABC has reported that wreckage from the plane - including a propeller and pieces of the fuselage, wing and engine - have been recovered by the SA Navy's hydrographic survey vessel, SAS Protea.
