NHLS Board Chair who discovered irregularities in Feb 2017, immediately suspended Mogale and Zulu, reported to National Treasury, requested SIU investigation. Oversaw 2-year disciplinary process (criticized for delays but ultimately secured dismissals May 2019). Accused executives of "delay tactics and legal technicalities." Mixed record: acted on discovery but 4-year Board oversight failure (2013-2017) allowed R4.4B irregular expenditure.
