Against the run of play it was New Zealand who took the lead early in the second half.
A defensive mistake allowed New Zealand to attack inside the circle and from a scramble it was Tynan who forced the ball across the line as the Irish players stood and watched.
The equaliser came just four minutes later.
From a penalty corner routine that didn’t go according to plan, the ball inadvertently found its way to Katie Mullan who squared it across goal for Hawkshaw to tap in.
As the final quarter began so did the thoughts of another shootout for Ireland.
However with nine minutes remaining in the game, Hawkshaw drove along the goal line and her pullback was superbly turned into the corner of the net by Torrans.
Ireland held on for a famous win and the opportunity to play for a place in world hockey’s premier competition.
