Nayler was a member of the
New Zealand U-20 side at the
2010 and
2012 Women's World Championships, playing in all three of New Zealand's group games at both events. The performances earned her a spot at the
senior New Zealand team, the "Football Ferns", for the
2011 FIFA Women's World Cup. Nayler was the only uncapped member of New Zealand's squad and did not feature in the tournament. She was also a standby player for the
2012 Olympics. Nayler's eventual senior début happened at the
2013 Cyprus Cup, in a 2–0 win over
Italy. She played all three matches of New Zealand at the
2015 FIFA Women's World Cup in Canada. Nayler was chosen as Player of the Match during her second game, as she kept a clean sheet in a 0–0 tie with
the hosts in Edmonton. In 2015, Nayler was captain of
Northern Football as they won the
National Women's League, the top-flight women's football tournament of New Zealand. She also played for
Norwest United of the
Northern League. However, she was released by Sky Blue after 26 days and no games played, and Sky Blue signed another outfielder instead. Nayler then hoped to use the
2016 Olympics, where she was again the Ferns' starting goalie, to see if she attracted the attention of any foreign clubs. In the Olympics, Nayler had a clean sheet in New Zealand's second game, a defeat of
Colombia by 1–0, but the Ferns fell in the group stage following defeats to the United States and France. Shortly after the Games, Nayler signed a two-year contract with
Olympique Lyonnais of France. In 2017 she was loaned to women's team of
Grenoble Foot 38, who played the
Division 2, after seeing no playing time as the third goalkeeper. For the 2017–18 season, Nayler signed with the female squad of
FC Girondins de Bordeaux, who played in the
Division 1. At the end of her first season, where Bordeaux finished seventh, Nayler renewed her contract for an additional two years. In April 2019, Nayler was named to the final 23-player squad for the
2019 FIFA Women's World Cup. In August 2020, Nayler announced she had signed for
FA Women's Super League club
Reading. Unable to dislodge the incumbent goalkeeper
Grace Moloney and unhappy at a lack of playing opportunities, Nayler left after one season. On 27 October 2021,
Damallsvenskan club
Umeå IK announced the signing of Nayler ahead of their
2022 season, where she played during 2022. On 1 December 2022, Damallsvenskan club
IFK Norrköping announced the signing of Nayler ahead of their
2023 season.
Bayern Munich announced in August 2023 that Nayler had signed a one-year contract with the club. ==Honours==
