Seventeen-year-old Jordan (Yamaha WR450) finished 58th overall, good enough for ninth place in the U19 category.
Nineteen-year-old Ashley (Yamaha YZ125) finished 113th overall while her mum, Michelle (Yamaha YZ250F), was placed 118th overall.
The mother and daughter pairing earned seventh and sixth place respectively in the women's class.
For Michelle, this was her 14th assault on the Tarawera 100 and she believes this may have been her toughest yet.
"[Mainly] because my motherly instincts came out and I was constantly worrying about the others," she said.
"In the end, I just tried to concentrate on what I was doing and I knew we'd all get together at the end of the day to share our experiences."
