Rotherham boss Steve Evans has sanctioned the move so Hunt - who made 161 appearances across 10 seasons at Bolton - can benefit from the opportunity of much-needed match practice. Stanley counterpart Leam Richardson is delighted to have the 29-year-old on board to fill his team's problem position of right-back.
"Nicky's got vast experience and he's played at every level in the Football League," Richardson told Accrington's official website.
"It's been a position that we've been crying out for all year. People have been in there and done a good job but right-back is a position I'd identified that we needed to fill."
Hunt joined the Millers in the summer after leaving Preston but he has been restricted to nine appearances this season and last featured as a substitute in November's 3-2 defeat to Wycombe.
Richardson added: "With Nicky's experience and his quality going forward and defensively hopefully we've filled that gap.
"He's a player I targeted quite early on and he was really eager to come and play for Accrington Stanley.
"He's been in touch wishing us luck and really showed a hunger to come and play for us. I really, really like that in a professional."
Hunt, who also counts Birmingham, Derby and Bristol City among his former clubs, goes straight into the Accrington squad to face Chesterfield on New Year's Day.
