Kidderminster substitute Anthony Malbon rescued a point against Southport, but could not stop his side hitting the foot of the Blue Square Bet Premier.
The hosts led at the break, midfielder Kyle Storer scoring his first goal of the season with a 25-yard drive.
Southport struck twice in six minutes through Karl Ledsham's 30-yarder and Tony Gray's penalty, after Nathan Vaughan brought down Shaun Whalley.
But Malbon came off the bench to head home just two minutes from time.
