Betsy Hassett grabbed a consolation goal for New Zealand but USWNT produced a stunning performance to earn its first win at the Olympics.
USWNT went into the game looking to recover from the shock loss against Sweden in the opening match which ended a 44-game unbeaten run.
Lavelle got USWNT off to the perfect start after nine minutes after she received Tobin Heath‘s through ball and produced a composed finish.
Horan thought she had doubled the lead after 35 minutes but her strike was ruled out by VAR for offside.
Just before the break, Horan scored from close range with a header with Megan Rapinoe providing the assist.
Nine minutes later, New Zealand capitalized on some poor defending to score through Hassett.
However, USWNT responded with late strikes from Press and Morgan as well as a C.J. Bott own goal to seal a comfortable win.
