Molosi signed the deal last Monday after writing to the department about his intention to plead guilty.
Molosi reportedly blamed officials, including himself, who felt pressured into cutting corners and taking short cuts because the project involved the president’s home.
Eleven other officials, all represented by the Public Servants Association (PSA), may sign similar deals to avoid lengthy hearings, the newspaper reported.
Roshan Lil-Ruthan, the PSA labour officer representing the officials, said his clients intended to tell the hearings they also felt pressured into speeding up the Nkandla upgrades.
In November, a parliamentary committee comprising exclusively of African National Congress (ANC) members accepted a report on the upgrades. The adoption followed a debate in parliament on report.
That report asserts President Jacob Zuma did not benefit unduly from renovations to parts of the property, including the construction of an auditorium, chicken run and a swimming pool.
Public Protector Thuli Madonsela filed a report entitled ‘Secure in Comfort’ which asserted President Zuma unduly benefited from the investment in the property.
