"I'm really excited," was all she could say to the Rotorua Daily Post.
Mrs Gaskill-Maxwell said it was a huge milestone for Paige.
"I never thought we would see this day. To be honest, we were told if she didn't have surgery she definitely wouldn't be here in two years."
Both parents dropped her off with older brothers Regan and Jaymie. Regan kept peeking through the classroom window to make sure Paige was okay. Another brother, Bailey, goes to Mokoia Intermediate.
"We've had nine years of kindergarten with all the kids and now they are all at school," Mr Gaskill said.
Mrs Gaskill-Maxwell planned to make the most of being child-free for a few hours to go cycling. She was a little anxious for her girl, though. "She's gone from kindy with 40 kids to 600-plus kids at school."
Paige goes back to Starship in October for more tests.
"We have to take it day by day, one day at a time ... this is a breeze compared with the last two years, though," Mrs Gaskill-Maxwell said.
Meanwhile, Paige is waiting for a Mickey Mouse Clubhouse birthday cake to arrive for her birthday this Saturday.
