Her grandmother, Lena McTaggart, played for New Zealand and Otago, and is a life member of Netball Otago.
Her mother, Noeline Duerden, also played for Otago.
So there was little room for escape, not that Tasi-Cordtz ever looked for the hatch.
"I was pretty much raised on a netball court," she said.
"Netball runs in my family. It's in the blood."
Tasi-Cordtz represented Otago at age group level and, at 36, the midcourter is not quite ready to retire her bib.
She still makes the odd cameo for her club.
But it is from the sidelines where she is set to make her greatest contribution.
A Southern club stalwart, Tasi-Cordtz started coaching as a 24-year-old and has had the benefit of working with former Otago coach Georgie Salter for more than decade.
She also worked alongside former Silver Ferns coach and Netball New Zealand president Lois Muir at the Otago Rebels.
"Georgie was the one who kind of tapped me on the shoulder. That's how I got into coaching. I absolutely loved it and just kept going from there."
Tasi-Cordtz guided the Otago Under-21 team to the final in 2006 and then took a break from coaching to spend more time with her young family.
Her husband, Rea Tasi-Cordtz, is involved with colts teams at the Dunedin rugby club and the sporty couple have two children - Taitelea (4) and Teuila (2).
Having made her way up through the ranks, Tasi-Cordtz took over the Otago reins from Nicola Jones at the end of last year.
"It is a real honour to lead your province, especially when you are really passionate about it."
One of the biggest challenges ahead will be getting her side to believe in itself.
The Otago team is full of young and up and coming talent.
The core of the side played in the Lois Muir Challenge and in the Otago Under-21 team.
But it is a big step up from those competitions to the national championship.
And with the likes of Jodi Brown and Jo Morrison unavailable, and Otago player of the year Emma Moynihan playing for Southland, the team's leadership group has been decimated.
It is a point the Balmacewen Intermediate School teacher freely acknowledges.
"I wouldn't say it is a concern. But [experience] is certainly something that we are very light on. The girls are really good off court but sometimes it is just those little things on court that I can't be responsible for."
Tasi-Cordtz's coaching philosophy is to encourage players to take ownership.
But that does not mean she will let the reins get too slack.
"There is a time and a place to rant and rave and put the hard word on. I can certainly do that. But there is also a time when you say 'Let's do this together'."
Otago played Canterbury in two warm-up matches last weekend and was comprehensively outplayed.
Following the patchy performances, Tasi-Cordtz said there was a lot of work to do before it opens its campaign against Wellington in Porirua on September 4.
