Aged just 17, she is playing her third year in the national women's league and was a key figure in a historic win for Dunedin Technical earlier this season.
Having also played plenty of representative age-grade football, the year 12 Columba College pupil travelled to Singapore in September with the New Zealand secondary schools under-18 team.
The team played four games away - including one against the Singapore national side - and won all four.
Gray said it had gone well and she had taken plenty of confidence from the trip.
''It was a really good experience, just to play at that international level and also with the top players in my age group in the country.''
One of the region's most promising players, Gray was named Football South 2017 young player of the year.
The honour came after her first season of premier women's football with Dunedin Tech.
Before that, she played in the youth boys' grades for Mosgiel.
While the Tech team has dominated locally in recent years, it took that to another level this year by making the semifinals of the national women's knockout cup.
Gray proved key in the 3-2 quarterfinal win over the Coastal Spirit (Christchurch).
In what Tech coach Graeme Smaill called a key moment, Gray put in the cross for Sophie Dijkstra to score on halftime.
''That was really cool,'' she said of her cup experience.
''I didn't know much about the knockout cup before I played for the women.
''It was obviously a really big deal for the team, because it was the first time a team from Football South has made the semis, so it was really cool to be part of that.
''It was definitely a big step up to the Auckland teams compared to the teams down here.''
Gray also played for Columba College in the midweek schools competition and said she enjoyed helping the younger players come through.
While she had one more year left of school, the New Zealand team only goes away every second year.
However, Gray said she would keep working to see if she could make the under-20 World Cup squad next year, alongside another season with Southern United.
She had thought about looking into going to the US on a scholarship after leaving school, although she likes Dunedin and is unsure about leaving the city.
Her ultimate dream was to play at a World Cup, but whatever happens she wants to keep playing and working as hard as she can.
Promising Otago Girls' High School goalkeeper Jade Middleditch was selected for the New Zealand secondary schools team but was forced to withdraw due to injury.
