During the ANZ Championship era, Fitzpatrick played for Northern Mystics, Waikato Bay of Plenty Magic and Southern Steel.

She subsequently worked as a teacher at Auckland Girls' Grammar School for thirty years.

[1][2][3][4][5][6] Two of her uncles, Olo Brown and Tana Umaga, were New Zealand rugby union internationals.

[1][7][8] Her younger sister, Theresa Fitzpatrick is a New Zealand women's rugby union international.

[1] For high school, she attended St Cuthbert's College where she was deputy head girl.

She was aged 17 and still attending St Cuthbert's, when she made her ANZ Championship debut with Mystics during the 2010 season.

[23] During the 2011 season, she formed a very effective partnership with Casey Williams and was subsequently nominated as Best Young Player.

However she was only a bit-part player as Magic won the 2012 ANZ Championship as she found herself kept out of the team by Leana de Bruin.

She formed a defensive partnership with Rachel Rasmussen, keeping Storm Purvis out of the team.

[34] However, Fitzpatrick's relationship with Mystics head coach Debbie Fuller became strained and she subsequently found herself dropped from the starting seven.

Normally, a season-ending injury, in Fitzpatrick's case, medical staff took the rare step of opting not to do surgery, as they determined the muscles that support her knee were strong enough to compensate for being short a ligament.

In 2010 she captained the New Zealand Secondary Schools team to victory in an International Schoolgirls Tournament.

[73] On 3 October 2011, Tone-Fitzpatrick made her senior debut for New Zealand against England during the 2011 Taini Jamison Trophy Series.

[78] However, Fitzpatrick would have to wait another seven years before been recalled to the senior New Zealand team for the 2018 Constellation Cup.

[84] On 22 September 2021, in the absence of an injured Crampton, Fitzpatrick captained New Zealand against England during the 2021 Taini Jamison Trophy Series.

[101] Fitzpatrick has spoken openly about her family life, her mental health battles, struggling with depression and anxiety, food and alcohol issues, her pregnancy and the pressures of being both a mother and netball player.
