Lunga was on the books of Chicken Inn in his homeland and has been training with Abafana Bes'thende for a few weeks now.
Arrows coach Clinton Larsen also revealed that he was assessing the left-back at the club.
The 23-year-old comes at a time when the club is in desperate need of a left-back after the departure of Lehlohonolo Nonyane, while Zolani Nkombelo recently suffered a serious injury at training.
“The club has signed Divine Lunga and he’ll be with the team this coming season,” a source tells KickOff.com.
Lunga was part of the Zimbabwean side that recently won the COSAFA Cup in Polokwane. He played in all three matches on the Warriors’ way to glory.
He’ll be the third Zimbabwe player at the club, with striker Knox Mutizwa and defensive midfielder Danny Phiri already on the KZN side’s books.
