The Urban Warriors signed the Zambia international last month after he impressed head coach Stanley Menzo and his technical team.
“Kabwe is a brilliant No 10 who scores and creates goals,” Efstathiou said.
“He netted 10 goals for Zanaco last season and will be a tremendous asset to the club. He is a class player.”
Kabwe had a great 2016 helping Zanaco win the most coveted trophy in Zambia, the MTN FAZ Super League title, ahead of ZESCO United.
The left-footed player could make his Absa Premiership debut when Ajax take on Bidvest Wits on February 7.
