Ireland's best performance at a World Cup tournament came in 2014 when they finished fourth after defeating New Zealand and winning Pool B. After defeating the United States 23–17 in their opening pool game, Ireland faced New Zealand, the 2010 Women's Rugby World Cup winners in their second game. With tries from Heather O'Brien and Alison Miller and two conversions and a penalty from Niamh Briggs, Ireland defeated New Zealand 17–14. It was just the second match New Zealand had lost in a World Cup tournament. It was the first time the Ireland women had played New Zealand and they became only the second Irish team, after Munster in 1978, to defeat a New Zealand national rugby union team. The result has been described as "one of the biggest upsets in the tournament's history". Ireland subsequently qualified for the semi-finals with a 40–5 win against Kazakhstan. Ireland eventually finished fourth in the tournament after losing 18–25 to in the third place play-off.
