Scott Boden’s double condemned Morecambe to a third straight defeat as their defensive woes went on.
The striker stunned the Globe Arena after just 56 seconds as The Shrimps failed to clear a corner before bagging the winner from an Alex Rodman cross 20 minutes from time.
The hosts had looked like turning things round thanks to Shaun Miller’s 12th of the season, a fine strike on the hour, but came up short as Newport picked up their first ever victory over Jim Bentley’s side.
Having been so disastrous defensively as they capitulated to defeat against Mansfield on Tuesday night The Shrimps picked up from where they left off as the visitors went in front inside a minute.
The hosts failed to clear Mark Byrne’s in-swinging corner with Boden hammering the ball home from close range.
Bentley’s side were nearly level a minute later but after Kevin Ellison had volleyed goalwards Darren Jones’ deflected clearance hit the top of the bar on its way over.
The Morecambe backline continued to look far from secure as chances flowed in the early stages.
Medy Elito fired narrowly wide from distance before Boden’s shot was saved by Barry Roche at his near post, Jones heading over the resultant corner.
The openings were coming at both ends however, Tom Barkhuizen was denied by Mitchell Beeney in on goal after 12 minutes with Jamie Devitt’s follow-up being cleared off the line.
The game calmed after the frantic opening with the wind playing its part in what was a poor spectacle.
The Shrimps had the first opening of the second half but Beeney had no trouble in holding onto Ellison’s free-kick as the game continued to lack any kind of spark.
Beeney was again on hand shortly after to keep out Barkhuizen’s low shot from 20 yards after a driving run at the County defence.
The leveller came on the hour mark out of nothing and was worth the wait.
Miller and Devitt exchanged slick passes down the right with the front man drilling home an unstoppable strike from 25 yards.
Having provided one assist Devitt nearly grabbed a goal of his own on 67 minutes but fired a shot narrowly wide from 25 yards after a flowing move.
But it was the visitors who went in front for a second time two minutes later.
Rodman crossed from the right with Boden guiding the ball home almost unchallenged to restore Newport’s advantage.
The Shrimps pushed for a leveller as they looked to arrest their recent slide, Devitt seeing a second shot from distance go just the wrong side of the post on 83 minutes.
Their best chance came three minutes from time however, Ellison dragging his effort wide when released in the area by a Paul Mullin backheel.
