He replaced former minister Ngoako Ramatlhodi who had resigned as a Member of Parliament after he was axed in an unexpected cabinet reshuffle in March 2017.^[3][4]

Mbuyane stood as an ANC parliamentary candidate in Mpumalanga in the 2019 national election and was elected back to Parliament at the election.^[5][6] He is a member of the Portfolio Committee on Trade and Industry.^[7]

In October 2020, Mbuyane unsuccessfully attempted to exclude the public from attending a virtual committee meeting of the Portfolio Committee on Trade and Industry to discuss the appointment process of a new National Lotteries Commission (NLC) chairperson. Mbuyane said that the committee had agreed to hold the meeting in private but it was then pointed out to him that portfolio committee meetings are public by default.^[8]
