City snapped up the Zimbabwean, who left Tunisian outfit Club Africain in October last year, on transfer deadline day as a free agent.
The title contenders also added Ugandan winger Allan Kateregga, Bradley Ralani, Masoud Juma and Kwanda Mngonyama to their roster in January, having recently lost key personnel in offensive duo Aubrey Ngoma and Lehlohonolo Majoro.
Rusike previously joined Amakhosi at the start of the 2012/13 campaign following a dispute-laden move from Jomo Cosmos.
The 27-year-old saw limited game-time at Chiefs before moving overseas when his contract expired in June 2015.
Rusike's also had stints at Nacional Madeira, Halmstads and Helsingborgs IF.
