The games were held in Invercargill from Friday until Sunday, attracting more than 800 athletes from around New Zealand.
About 80 athletes aged from 7 to 14 from Dunedin clubs took part.
Collectively, they won an impressive haul of medals — 10 gold, seven silver and 10 bronze.
Ora also won bronze in the 800m event.
They have been involved in athletics for a few years and only started distance running last year.
Ora said she wanted to compete in the games to try something new.
She was surprised but happy when she won her medals.
This year’s event was her final outing, as she will now move into senior competitions.
She added a bronze in the grade 14 long jump to her collection.
She won her first medal — a gold in the grade 10 100m sprint — in 2018.
Over the years, as the competition got tougher, she learned to aim for and value getting a personal best while competing, Ohara said.
She would miss competing at the games and seeing the friends she had made over the years.
For now, her goals were to reach 5m in the long jump, shave some time off her 100m sprint and "get the best out of myself".
"I want to make the best of it," she said.
