Cook Islands star athlete, Alex Beddoes, placed fourth in the 800 metres final with a solid time of 1.51minutes.
Athletics Cook Islands president Erin Tierney said it was a tight finish between the top four athletes from New Zealand, Australia and the Cook Islands.
Beddoes, who is using the championship as his final preparation for the upcoming Pacific Games, tried hard but fell short of a podium place finish.
Another great feat was achieved by national discus thrower Apii Tapoki, who placed sixth with a top throw of 46.13 metres. Tapoki will also represent the country at the Pacific Games, which starts next weekend.
Elijah Poila finished sixth in the under-18 discus final with a top throw of 40.44m.
In the U18 100m sprint, Albertto Arokapiti set a personal best of 12.09 seconds, Estelle Short clocked her best score of 13.50s and Jordayn Matutu followed with a personal best of 13.60s.
In the U20 100m sprint, Moe Marsters and Nelson Tangaroa both managed personal bests of 12.07s and Tikove Piira clocked 11.54s as his personal best time in the event.
Tierney said Piira narrowly missed out on a semi-final place.
In the U20 400m finals, Nelson Tangaroa recorded a personal best time of 54.89s.
Tierney said this was a massive 3.6 second improvement for Tangaroa in six months.
“We came to do a job, and we did that. It was a high pressure day for our sprinters, we demanded fierce and focused performances and we got that,” said Tierney.
She said they are super proud of how the whole team conducted themselves.
The team also attended an athlete seminar by sports psychologist Dr Jo Lukins where they learnt how to gain the mental edge, which Tierney said will be a vital tool for competition mind-set.
The team will return to Rarotonga this weekend.
