While rampant form in the Oceania women's nation cup in 2010 boosted her career tally, she is no flat track bully as vital goals against more vaunted opposition like Argentina, Italy, and the Netherlands testify.
But Hearn knows she faces an even tougher test against a United States side which has conceded just two goals in their last eight games.
"We're certainly aware of their record and know that they haven't been scored against in a while, so obviously breaching that defence is something we're definitely keen on doing.
The match, in Frisco, is the first for New Zealand since a 2011 World Cup which saw the team's overseas stocks swell to over a dozen, but also saw rivals Canada recruit five of their World Cup staff.
Despite the losses in personnel, Hearn had confidence the Ferns could topple the Americans for the second time.
"As individuals and as a group we're a lot more experienced now. We all know what we need to do and the girls are really hungry."
The match kicks off at 10am on Sunday.
