"I enjoy the work that goes into it and when you succeed in feels good," Lucy says.
"I think I am a competitive person, I have tried my hardest in everything.
"As I have grown up the training has just been part of my daily routine. It is not getting easier, but it is manageable."
The Bartletts share the same drive to compete and Lucy says it is a big part of their family.
"It is awesome having Monique competing there, she is a really good athlete. But we don't talk about surf too much at home, you have to take a break."
Monique echoed her sister's enjoyment of the sibling support.
"If I am not racing I can go and cheer my sister on, and she will cheer me on," Monique says.
"I love having her there, it is a special thing because not everyone has their sibling at the events with them. I have always wanted to be as good as, or even better than her, she inspires me to keep on going."
Monique says she has loved the water as far back as she can remember and her success at the Oceans event is down to the work she has done in the lead-up to the event.
"Last year I didn't do so well so I want to come back and do well this year. I felt much better, during my surf race I felt like my swimming training had paid off. I had been doing four or five trainings each week, some days up to an hour and a half."
Lucy now has her sights set on higher achievements, having gained confidence from her success last week.
"I want to compete at the world champs and win an international title one day. The mornings when I don't want to get up, I have to think about that goal. I will need to plan ahead and train hard, but also not overload myself."
Some of their medals came in team events with their Ōmanu team mates, and it is the club's coaching that the girls' father, and team manager, Scott Bartlett says is at the heart of their success.
"The programme is good and there is a good support network as well. We have involvement with the Mount Maunganui swimming club and it is about creating a good base of community networks," Scott says.
"The girls have worked hard for the past six months. They have been pretty focused, not just for themselves, but for their teams.
"The beauty of the team environment is they have to interact and communicate with each other. Even the little things like being in the team tent and wearing the uniforms is important."
Scott coached the New Zealand team for nine years and won medals in the Australian national championships as a competitor. He says balance is an important part of the girls' regime.
"They are pretty grounded kids and they set their own goals and understand the hard work they have to do. It is them who have to drive it."
