Gaxa signed on a free transfer even though a contract disputewith Kaizer Chiefs remains unresolved.
“We needed some cover with our defenders, he was available, he has been training with us and looked okay. He is not really match-fit but he is into the fray and in contention for the SuperSport game,” said Hunt.
Wits are looking to bounce back from the disappointment of a 2-2 draw in their last league game at home to Highlands Park, though they are still leading the Absa Premiership.
The Clever Boys conceded a stoppage-time equaliser and Hunt said: “We are disappointed but we must keep going.”
The Wits coach expects a difficult game against Stuart Baxter’s SuperSport in Nelspruit. Matsatsantsa have not lost any of their last 12 games in league and cup and on Saturday beat Orlando Pirates to reach the Telkom Knockout final.
“They are flying and we are flying,” added Hunt.
“They have done well to get to the final. They have a very strong squad, and they have spent a lot of money.”
Wits will be without suspended left back Sifiso Hlanti, who was sent off against Highlands Park.
SuperSport are currently third on the league table, three points behind Wits, though Stuart Baxter’s side have played two games more.
Wits will have good recent memories of Mbombela, having won their MTN8 there earlier this season, beating Mamelodi Sundowns 3-0 in the final.
