The Mamelodi Sundowns goalkeeper was unveiled with five other players during the club’s annual end of season awards ceremony.
The other signings are: Limbikani Mzava, Rodney Ramagalela, Wayde Jooste, Makhehleni Makhaula and Marks Munyai.
“Welcome home Thela Ngobeni, safe guarding them posts,” read a tweet from Highlands.
Ngobeni will be looking to get game time at the Lions of the North having fallen down the pecking order at Sundowns.
The 30-year-old failed to make a single appearance for the Brazilians, having returned from a loan spell at Free State Stars at the beginning of the season.
