"When I was a Year 7 student at John Paul College, I looked up to the school leaders and was impressed by the influence they had in the school," she said.
"At that young age I decided I wanted to be given the chance to have that type of influence in my final year.
"Being head girl this year is definitely a bonus, but I wouldn't have been disappointed if I was put in a different leadership role. The main thing I care about is making a difference for the younger students."
Rebecca said one of her main goals was to encourage more integration between year levels.
"I want to make sure the younger students know they can come to us if they need to talk about anything. I want to be known as an active leader, not a figurehead.
"We run a peer-support programme where the senior students spend time with the junior students. Through initiatives like that, we are encouraging more interaction and making the school feel like a second home, rather than an institute."
Arvin said when he started at John Paul College he was "quite scared and intimidated".
"It feels like a big school when you start so that can be very daunting for young students. I remember walking through the gates as a Year 7 and I was so scared, but the leaders at the time made me feel safe and comfortable ... they made me feel like I was not only a part of the school, but a part of their family"
Arvin said creating a greater sense of school spirit was also one of his objectives.
"I want students to feel proud when they tell people they go to John Paul College. School spirit is not something you can force or impose, it's something you have to foster and lead by example."
Both students agreed their leadership was about helping others in the school.
"As junior students, Rebecca and I had some amazing leaders looking out for us and contributing to our overall school experience. This year we want to continue that tradition and form closer relationships with the younger students."

Rotorua Lakes High School
Head girl: Jessica Gordon

"I am looking forward to the many opportunities this role brings. It will be great to work alongside the prefects and staff in order to inspire students to thrive during their time at our school."
Head boy: Tamihana Gardiner
"I wanted to be a leader at Rotorua Lakes High School because it gives me the opportunity to set an example for students, particularly for students who have transitioned between full Maori immersion schools to mainstream education, like myself.
"This year I hope to achieve in my school work to an excellent level and also to be the best role model possible at Rotorua Lakes High School in 2015."
Rotorua Boys' High School
Head boy: Rawiri Manley
"Being a leader for the school was always in my plan. When I started in Year 9 Jordi Webber was the head boy and I remember idolising him and wanting to be a strong leader like him in my final year.
"As a prefects team we recognise there is a big gap between the Year 9 students and the Year 13 students. This year, one of our goals, along with fostering a strong sense of brotherhood, is to bridge the gap between year levels through more team building activities and tabloid days."
Co-deputy head boy: Matangireia Yates-Francis
"I always liked the idea of being a leader and I think there were a number of experiences during my time at Rotorua Boys' High School which contributed to my desire to become a leader in Year 13.
"I remember many of our past school leaders as great young men and hope to leave my own legacy at the school. We already have a very strong sense of brotherhood at Rotorua Boys' High School so this year we hope to continue that and keep the spirit alive."
Co-deputy head boy: Logan Elers (left)
"Going into Year 13 the biggest aspiration you can have is becoming a school leader. Being made a prefect was always something I had considered and worked towards during my time at Rotorua Boys' High School and I am pleased I was able to make that goal a reality this year.
"Together with Rawiri and Matangireia, I want to help the school become the most outstanding boys' high school in the country."
