The Iron could have moved to the summit, for 48 hours at least with leaders Chesterfield in action on Monday, but Chris Zebroski's injury-time goal kept them in second.
Lee Minshull had put Newport ahead midway through the first half, although Paddy Madden's strike just after the hour mark and David Syers' 83rd-minute goal looked to have given all three points until Zebroski rescued a share of the spoils.
Scott Hogan fired in a hat-trick as Rochdale strengthened their bid for automatic promotion with a 3-0 win against Oxford at Spotland.
Hogan's goals in the 45th, 50th and 62nd minutes underlined the home side's superiority and moved Keith Hill's men five points clear of the play-off places.
Billy Kee's double against former club Accrington clinched a 2-1 win for promotion hopefuls Burton.
Kee grabbed the 79th minute winner from the penalty spot after his first-half opener had been cancelled out by a Dean Winnard goal.
Fleetwood and Southend, who sit sixth and seventh in the standings, were both held to draws by Wimbledon and Wycombe respectively.
While it was a goalless stalemate at Highbury Stadium, Daniel Bentley's own goal earned Wycombe a point after Barry Corr had put Southend ahead.
Torquay remain rooted to the foot of the table after a 3-0 defeat at Hartlepool, who claimed victory thanks to strikes from Jack Barmby, Luke James and Marlon Harewood.
Plymouth remain three points ahead of Hartlepool in eighth after thumping Morecambe 5-0, thanks to goals from Durrell Berry, two from Lewis Alessandra, Curtis Nelson and Andres Gurrieri.
York stretched their unbeaten run to five games and consolidated their place in the top half of the table following a 2-1 win over Exeter, with strikes from John McCombe and Michael Coulson sealing victory with Scot Bennett's goal for the Grecians only a consolation.
Byron Harrison's 82nd-minute winner gave Cheltenham a 2-1 success over Bury, who had taken the lead through Clive Platt only for Ashley Vincent and then Harrison to condemn the Shakers.
Northampton are four points adrift of safety after a goalless draw against Bristol Rovers, while there were also no goals in the clash between Dagenham and Mansfield.
