Youth Moore was a member of the
New Zealand U-17 side at the
2012 U-17 World Cup, playing in all three of New Zealand's group games. In February 2014, she took part in the
U-20 Oceania Championship in her home country. Moore played in two games and wore the captain's armband. With three victories, New Zealand won this championship. This qualified them for the
2014 U-20 World Cup in Canada, where Moore played in all of her team's matches. New Zealand finished second in the group stage behind European champions
France, making it to the quarter-finals of a World Cup for the first time. However, they were eliminated by eventual runners-up
Nigeria.
Senior Moore made her senior debut for the
Football Ferns as a substitute in the 4–0 win over
China on 26 September 2013 in the
Valais Cup final. In March 2014, she then took part in the
2014 Cyprus Cup, where New Zealand won the match for 11th place against
Finland. Two months later, she took part in the
2014 Oceania Championship, where Moore played in three matches. On 14 May 2015, she was called up to New Zealand's squad at the
2015 FIFA World Cup in Canada. She was substituted on in the 90th minute in the 1–0 win against
Colombia. She became a regular player from the
2017 Cyprus Cup onwards. On 10 June 2018, she scored her first goal for the senior national team in a 3–1 defeat against Asian champions
Japan. At the 2018 Oceania Championship, she played in four of the five games and scored two goals. As tournament winners, New Zealand qualified for the 2019 World Cup and the
2020 Summer Olympics. In April 2019, Moore was named to the final 23-player squad for the
2019 FIFA World Cup, however while in France training before the tournament started, Moore snapped her Achilles. At the 2020 Olympic Games in Tokyo, which were postponed by a year due to the COVID-19 pandemic, she played in two of the three games. On 20 February 2022, Moore scored a
hat-trick of
own goals in a match against the
United States at the
SheBelieves Cup. Moore is believed to be the second player after
Stan Van den Buys to score three own goals (although, as some sources mention, the third of Van den Buys's own goals was technically scored by
Johan Walem, who touched the ball prior to it crossing the goal line after the ball was directed into goal by Van den Buys).
ESPN reported that only the third goal was due to an obvious error, an ill-timed clearance kicking it into the goal. For the first, her block of a shot from wide bounced back into the net, and for the second, the ball hit her face to deflect into the net. United States coach,
Vlatko Andonovski, said it was unfortunate that Moore was so unlucky, adding that "she's incredible and ... her positioning was very [good]". In June 2023, Moore,
Ava Collins, and
Kate Taylor were named as reserve players for the
2023 FIFA World Cup. However, Moore declined to join the squad as a reserve player and
Grace Wisnewski was called up as a reserve player instead. On 4 July 2024, Moore was called up to the New Zealand squad for the
2024 Summer Olympics. ==International goals==
