Teenage midfielder Jorge Akers showed some dazzling skills in beating a defender on the right flank before making a deft cross but keeper Fernandez snuffed any thoughts the Rovers might have harboured to nudge ahead as the teams went into the changing rooms with the scores locked.
When play resumed, Blues coach Bill Robertson took off Akers, pushed rightback Charlie Yexley up to right midfield and injected Ethan Ladd to rightback.
But it was the visitors who went up 2-1 in the 50th minute when Cunningham side-footed a free kick from about 25m out almost on the goal line to ask more questions of the hosts' defence to hush the home fans into silence.
Leftback Danny Wilson and Oliver Coren were spurred into finding a tit-for-tat reply but the yellow brigade stood defiant in defence to deny the Rovers joy.
Robertson also replaced defensive midfielder Blake Koolen with English import Fahad Rwakarambwe in the engine room in the 67th minute but the equaliser remained elusive as dark clouds hovered and light rain did its bit on what was a crisp Bluewater Stadium surface.
It looked like the game was gone but that wily customer McIvor, left unmarked on the front post, nodded in the ball from a cornerkick from Blues skipper Joshua Stevenson to equalise, 2-2, in the 85th minute.
Taranaki's Dom Squatriti had a chance to push ahead after a deft back heel from striker Joshua Smith two minutes later but his finish was feeble and rolled into Hanks' hands.
It was the Blues faithful's turn to agonise after McIvor missed a chance to claim three points from point-blank range but found an errant defender's foot in the way.
Desperation kicked in as both sides found urgency amid silly fouls to break the stalemate but it was not to be as rain settled in.
