Luke Guttridge put the hosts in front with a marvellous long-range strike, before Jan Klukowski levelled the tie after half time.
Paul Benson then nodded Luton back into the lead, but Newport levelled once more as former Hatter Aaron O’Connor headed home.
However, Luton went on to triumph thanks to Ricky Miller’s first goal for the club and Jake Howells’ fine solo effort.
