But she still walked off the field feeling slightly disappointed.
The Ottawa Fury star actually had her sights set on a double hat-trick and felt she should have achieved that aim.
“I did set myself a target of six and obviously I didn’t reach that,” she says.
“I missed a couple of sitters which I should’ve finished off. But it’s still a good start and life is good.”
The few chances Hearn did let pass her by did not matter in terms of the result. That was never beyond doubt after she notched a quick-fire hat-trick within the first 18 minutes and Hannah Wilkinson also got in on the act with another four strikes.
But Hearn is keen to get into good habits now so that, when a big chance does come along in a hard-fought match, she is ready to take it.
“I want to keep up my standards,” she says. “Finishing is the key thing for me to focus on because you’re never going to get the same number of opportunities playing against tier one or two teams.
“The teams that we’re playing are not as experienced as we are and we’ve got the Peace Queen Cup coming up so we need to keep our standards for that.”
New Zealand coach John Herdman was pleased with the professionalism his players showed in not taking their foot off the gas against Vanuatu and Hearn says complacency isn’t an issue.
“We’ve got so many people in the team that motivate you to just keep pushing and pushing. Even if it’s hurting, you just keep doing it.”
New Zealand’s next match is on Friday at 3.30pm against Cook Islands, who are on a high themselves after posting a 1-0 win over Tahiti – their first ever victory at senior women’s level.
