The commission, which wrapped up its work in April, had requested a further extension to finalise its report by the end of May.
Mchunu will have the final say on whether the report will be made public. However, his office recently indicated that the transcripts would not be made public because key witnesses would be compromised, but there was a possibility that the transcripts may be released at a later stage with the witnesses' names censored.
However, civil rights organisation Right2Know Campaign has demanded transparency in all issues pertaining to the Moerane commission, especially in accessing transcripts and ultimately the report of the commission.
During his evidence, Zulu told the commission that he had submitted a document dealing with political killings to former acting provincial police commissioner Major-General Bheki Langa in June 2016 ahead of the local government elections but never received a response.
He also told the commission that Magaqa gave him documentation allegedly proving corruption in the tender for upgrading the Umzimkhulu Memorial Hall, which ballooned from R4-million to R37-million even though the work has not been completed.
Zulu also blamed police inefficiency in dealing with the political killings and the fact that many high-ranking police officials were serving in an acting capacity.
He also said political killings in the province were as a result of factions within political parties and a scramble for tenders.
