New Zealand coach Aaron McFarland said the goal just after halftime changed the game.
"Going into that game as much as we talk about having a positive mindset, in the back of your mind it's hard to get rid of that nagging thought telling you just need a draw, so when they score that first goal the mental focus now needs to shift. I didn't think we were ready to take the game by the scruff of the neck from the outset.
"We're happy to keep the ball but at certain times when we are talking about being positive and trying to win the game it didn't feel at times like we had full belief in our own abilities to get on the ball in the final third and make things happen.
"That'll come with more exposure. Playing more games, more frequently will help our players get over the fear of trying to play that style of football under that sort of pressure.
"I hope people back home have taken notice. There's huge potential for the women's game in New Zealand to blossom and there's a lot of good role models even in this team for young girls to aspire to emulate, and hopefully the positives from this campaign will drive more growth and more success."
