As earlier reported by KickOff.com, the former Kaizer Chiefs defender will reunite with coach Roger Sikhakhane at Amabhubesi for the upcoming campaign.
The Chilli Boys recently signed Macheke on a two-year deal after his contract was terminated by Amakhosi in May.
"Defender Zitha Macheke has joined NFD outfit Thanda Royal Zulu on a season-long loan. Macheke signed a two-year contract with CUFC effective July 2016," Chippa said on their Twitter account.
United today also announced the capture of ex-Chiefs fullback Simphiwe Mtsweni.
