Although she spent a year working at Bouzaid and Ballaben in Greytown to help pay for university, she was still getting to know Wairarapa.
"I need to orientate myself. I don't know a lot of the community and I'm working with new staff and a new station ... just to get to know how things are done in the Wairarapa."
Miss William, a police officer for eight years, was previously based at the Wellington central station.
She joins Sergeant Jennifer Nelley as Wairarapa's second female sergeant.
It was good to have a balance between male and female officers, Miss William said: "There's a lot of women working within the station ... and that makes it better balanced. It's a good, healthy mix."
Of Cook Island Maori and Pakeha descent, she spent five years teaching English in Japan after gaining her degree in Maori at Canterbury University.
With both parents working for the Air Force, the family moved around a lot, including six years in Singapore.
Miss William's goals include becoming a senior sergeant and continuing to find job satisfaction: "You have to enjoy what you do and if you are not enjoying it then you might as well leave. Life is too short to be unhappy."
