Having finished a marketing degree while playing in the top flight of English football in Bristol, the 24-year-old decided she wanted to travel and the lifestyle of Queenstown proved a strong lure.
Yet after having last year off, the sport proved too hard to resist.
She was influential for Queenstown FC in the southern women's premier league and won the female player of the year award, netting 18 goals along the way.
Since then, Isaac has scored in both of Southern United's national women's league games and was key in the opening-round win over Auckland.
Being based in Queenstown with a marketing job at Harcourts, the team had been accommodating and trained on Friday nights before home games.
That enabled her to travel to Dunedin without missing work, while for away games she flew out of Queenstown.
While disappointed with last weekend's loss, she is hopeful the team can bounce back against WaiBOP at Tahuna Park tomorrow.
``I always feel like we can win any game; it just depends on the day,'' she said.
``I think that's something the whole team feels now, especially after that first win.
``Anything's possible and we've got some talented players, so we'll see how it goes. I don't see any reason why we can't win the next game, or the game after that and the game after that.
``I'd love to get through to the playoffs. That's the kind of aim, I think.''
Originally from Cornwall, Isaac left home as a 16-year-old to join Bristol Academy, where she was coached by former England women's manager Mark Sampson, who was sacked last month as England manager following an inquiry into an inappropriate relationship with a young player.
One of England's women's top clubs, Bristol Academy plays in the women's super league 1 - formerly the women's premier league - and has twice finished runner-up in the FA Cup.
After a season on loan to Cardiff in the second-tier competition, she returned to Bristol and then had a break due to injury, before spending a season at Yeovill FC.
It is clear she comes from an impressive background, although she felt there was plenty of quality in the New Zealand league too.
``I wasn't sure what to expect coming into the national league.
``But there's definitely some good players that would slot straight into the English leagues, the top couple of leagues.
``I'd say the English league's a lot more physical in general.
``Playing the [New Zealand] national league compared to the regional league, there's definitely a big step up there now, but definitely the physicality of the English league is the main difference.
``There's a lot of good players over here [in New Zealand].
``And there's just more players in England so you're just constantly competing for your space a lot more.''
She is unsure what the future holds although she is not thinking of going home just yet.
Australia was an option next year, as its leagues began in February, while returning for another season with Southern could also be an option.
The Southern United men's youth team plays its second game of the season as the curtain-raiser to the women's game at Tahuna Park.
It hosts Eastern Suburbs at 1pm at Tahuna Park.
