Nazia was much more than a Pop singer. She continued with her education and, after taking her law degree, worked as a political analyst in the United Nations. Due to her interest in children, she was offered the opportunity to represent UNICEF for children's causes. Her music travelled with her and she decided to use it for a cause dear to her heart.

Nazia joined the United Nations in 1991 as an intern in 'Women's International Leadership' program and then went on to work in the UN Department of Political and Security council Affairs.

Using the almost ‘cult status’ she earned in the music world Nazia went on to do what she liked to do most, social work. Supported by the Ministry of Interior & Narcotics Control she formed an NGO known as BAN (Battle Against Narcotics) to help combat/reduce drug addiction in Pakistan. Concerned about the fast spreading menace, Nazia and her singing partner adn brother, Zohed launched a nationwide 'demand reduction' and awareness program  through their music.Referred to as 'Music with a cause' their first song entitled, 'Nasha Na Karo' (Don't do Drugs) not only topped the charts in Pakistan & India but also attained a No. 1 position on the Indonesian Top 10.

Nazia was also an active member and participant of social organizations such as The Voice of Women, National Youth Council, Business and Professional Women, The Rotary Club, The 300 Club (UK) and Inner Wheel Club for Disabled Children and organized fund raising programs for the United Nations.

She believed in using "music for purpose" — to care for and champion the cause of the downtrodden and the under-privileged. Social Service was her real passion. She regularly organised Polio and eye camps, contributed to the establishment of mobile clinics, assisted in the running of the schools, and provided medical supplies.
