Ten cells, each between 2x3m and 2x4m, were to be painted and 10 artists were chosen but two pulled out.
Ritete will paint bright sunshine and mountain ranges; others are using indigenous-style motifs and patterns, one is painting an aquarium and another is painting sky on the ceiling and grass on the floor.
"When I first saw the size of the walls, I thought, 'wow! What an opportunity' but I didn't know if I should have a go until a friend talked me into it ... "
While she has not been in trouble with the law, Ms Ritete knows about starting life anew. Now 26, the former Papakura High School student surprised her teachers - and herself - by displaying a natural talent for art.
It was the only NCEA subject she passed but she didn't think she could make a living from art. Instead, Ritete worked at fast-food restaurants and completed part-time study but there were periods of unemployment and uncertainty as she reflected on what to do with her life.
Three years ago, she decided to pursue her artistic dreams and enrolled for another qualification, the Certificate in Foundation Education (Pathway Visual Arts) at Manukau Institute of Technology. About the same time, she discovered the Papakura Art Gallery. She was warmly welcomed by gallery coordinator Leilani Kake, who has become a friend and supporter.
Since then, Ritete has gone on to study toward a Diploma in Art and Creativity, exhibited work in two shows and sold two paintings. She's joined forces with Kake to design and paint a mural at her former intermediate school, Mansell Senior School.
She also teaches art at a local alternative education provider and tells students not to be shy about exploring their creativity because it's an outlet for expression and a possible career option. She hopes those who see her work at the police station will find similar inspiration.
