Scunthorpe extended their unbeaten run to 18 games with a second-half recovery at Rodney Parade. The Iron's Paddy Madden had already cancelled out Lee Minshull's first-half effort when David Syers looked to have sent them above leaders Chesterfield when he scored seven minutes from time.
But Zebroski pounced in added time for his ninth goal of the season to snatch a deserved draw.
Wilcox said: "I'm a very proud man stood here. That performance told me all about the group I'm working with and where we are at.
"You have to give credit to Newport in the first half, their style of play was effective. They're quite direct, they get balls in your box, they have long throwers on both sides of the pitch and we didn't deal with that as well as we have done in the past.
"We've been done by two set-plays which is disappointing, but the response I got from the players in the second half tells me all I need to know about this group.
"It showed how together they are, how committed they are to achieve for this football club."
