The removal follows an investigation into alleged misrepresentation of its contractor gradings.
Public Works and Infrastructure Minister Dean Macpherson announced the decision at a media briefing on Tuesday, 27 October.
He said 15 contractors were removed from the register in October as part of a crackdown on misrepresentation in the construction sector.
Moriel was struck from the National Register of Contractors by the board on 15 October.
“The CIDB commenced its investigation into the company in 2025 and served its first formal notice that year,” Macpherson said.
He said the inquiry centred on concerns that Moriel had overstated its financial and technical capacity to obtain higher gradings, which determine the type and value of work a company is permitted to undertake.
This could have allowed it to secure government contracts for which it was not qualified.
At the time, Moriel held several high-level gradings, including 8 CE, 8 SB, 8 SK, 7 EP, 7 ME and 7 GB.
“The subsequent decision to remove Moriel from the National Register of Contractors thus demonstrates our approach is based on investigation, evidence and due process rather than speculation,” Macpherson said.
He stressed that the investigation began before the recent public controversy surrounding Mudzinganyama, although it was amplified by it.
“This was initiated before, but they were certainly amplified by a video showing an individual at a restaurant in Sandton,” he said.
In September, a video circulated showing Mudzinganyama threatening to shoot women during a confrontation at a restaurant in Sandton.
He later apologised, describing his language as unacceptable and unjustifiable.
