Both players will see their contracts expire in June, with neither expecting to don the team's colours again under new coach Ernst Middendorp.
"Definitely I will be leaving the club because they have already told me that I'm not in the plans of the coach," Paintsil tells KickOff.com.
The Ghanaian adds: "We as professional players need to understand that if the coach says you are not part of his plans I don't think we should force yourself, because at the end of the day, I know I played my part and when we finished in the top eight for the first time."
Hartog, who skippered the side and played 10 league games this season, says: "I'm not extending my contract again and my contract was expiring at the end of June.
"You see I don't want to talk about it because I don't want to say anything. But I can tell you I won't be playing for Maritzburg in the next six months."
