Rushden kept up the pressure on league leaders Hartlepool with a superb 2-0 win at Kidderminster.
The visitors, who knocked Kidderminster out of the FA Cup in November, completed a league double thanks to a brace from Paul Hall, who netted in each half.
They were in front after 15 minutes when Onandi Lowe picked up a through-ball from Paul Underwood before slipping a pass to Hall, who coolly slotted home from 15 yards.
Kidderminster hit back and Dean Bennett's goalbound shot was blocked by Stuart Gray, while Bo Henriksen's shot from 10 yards flew wide.
Rushden keeper Billy Turley then pulled off fine saves from Henriksen and John Melligan before Hall struck again on 69 minutes.
A 30-yard free kick from Lowe was fumbled by Stuart Brock and Hall had the simple task of tapping in the rebound to seal the points.
