President Jacob Zuma was thronged during a walkabout in Marabastad‚ west of Pretoria‚ on Monday. .
According to Corruption Watch spokesperson Bongi Mlangeni, 32% of the cases are related to grievances about banks, misconduct by lawyers, municipal mismanagement, and business-to-business fraud.
Mlangeni said 25% of cases still required further assessment as they were not easy to categorise.
"They were service delivery complaints which may be due to badly managed processes or a result of corrupt behaviour."
Corruption Watch has launched an application with the special investigating unit and the Gauteng department of health for access to the report of an investigation into allegations of fraud, procurement irregularities, and financial mismanagement in the health department.
Next month, the organisation will launch its first campaign and release its report into corruption in the Johannesburg Metro Police Department.
"This will kick off a major campaign aimed at reforming the JMPD and informing the public about their rights and duties in relation to corruption in traffic policing," said Mlangeni.
To report corruption, the public can visit www.corruptionwatch.org.za, send an e-mail to firstname.lastname@example.org or sms 45142.
