This year, Rarua was involved in the festival of Pacific arts, travelling to the Solomon Islands to participate.
In four weeks' time, she will travel to Frankfurt to represent her culture and country in a Celebration of Maori Culture in Germany.
Rarua says her motivation comes from her desire to embrace her cultural traditions as a symbol of her national identity.
She wants to be seen as a role model for younger Maori students to encourage them to embrace their culture and artistic heritage.
Next year, Rarua is going to spend time in Australia.
In 2014, she wants to attend university to study psychology with a focus on Maori tikanga and values.
