A first half Ashley Chambers spot kick had put Boro ahead, but the visitors levelled after the break with their own converted penalty.
Nuneaton began brightly and centre half Jon Ashton was inches from connecting with a Ryan Beswick corner, whilst Tom Elliott almost set Leon Lobjoit free in the opening stages.
At the other end Dean Lyness displayed sharp reflexes to deny both Joe Guest and Ben Wharton for Curzon.
Elliott and Daniel Nti then saw efforts well blocked for Dino Maamria’s team before the away sides resistance was broken minutes later.
Visiting defender Steve Howson was penalised for handball when attempting to block a cross giving Boro a spot kick.
Frontman Chambers stepped up and confidently dispatched from 12 yards as he rifled home right footed into the top corner.
However in what became a fiercely fought encounter, Boro were unable to extend their advantage, with Jordan Nicholson‘s late first half effort the closest they came before the break.
It was again Nicholson after the interval who came close thanks to a flurry of chances, but a rejuvenated Curzon began to threaten.
Initially Boro saw clear a number of half chances, but just before the hour mark the visitors were given the opportunity to level.
Wideman Nti was deemed to have tripped Wharton inside the area, allowing Niall Cummins to step up and level with a precise penalty.
Despite the setback Boro continued to push from all areas as full back Luther Wildin surged forward, before cutting inside only to see his low effort stopped by Cameron Mason in the away teams goal.
However a continuation of endeavour was not enough for Nuneaton to claim a winner, whilst Lyness proved resilient at the other end to ensure Boro went two undefeated under Maamria.
