Manager Michael Flynn says a victory over fellow promotion-chasers Forest Green Rovers would give his squad a positive shot in the arm.
County have found themselves in a difficult run of form of late, with the victory over Grimsby Town earlier this month being the first since the reverse fixture against the Mariners on 8 December.
The Exiles endured a frustrating evening in the 1-1 draw against Exeter City earlier in the week, having enjoyed a numerical advantage for large parts against the Grecians.
The point kept County in fifth place in the Sky Bet League Two table, but Flynn believes a victory over Rovers at Rodney Parade this weekend would reignite his side's promotion spark.
"A win would be huge," said Flynn.
"There are a lot of things that have gone wrong and we’re not in a good run of form. We should’ve won the last two, but we didn’t - that’s where we are at the moment.
"If we scored first on Tuesday night, we would’ve won the game and it was the same as Southend, but unfortunately we didn’t in either of them.
"If we weren’t creating chances, then it would be even more worrying.”
The promotion race is still wide open in an unprecedented Sky Bet League Two season, with two points separating fourth-placed Salford City and Carlisle United, who sit five places below the Ammies in the table.
County are level on points with Tranmere Rovers and Salford City in the play-off positions but could cut the gap on second-placed Rovers to just one point with a victory this weekend.
"We’re fifth in the table and if we were 18th, you could start saying the confidence has gone," added Flynn.
"We want to go on a run and win some football matches, but there are only a few teams who are winning more than two in a row.
"It’s tough for everybody and this season is unprecedented, but nobody has got more belief in this group than me."
