The two-year scholarship will allow Ms Wang to immerse herself in the world of public policy, an interest she developed during her "working-class" upbringing and schooling at Avondale College.
"I had a really great experience at Avondale and I wouldn't trade it, but certainly it makes you see a different side of the world you perhaps don't see when you get to university and you're surrounded by people who come from more privileged backgrounds."
She said this had shaped her social consciousness. "You realise to go to university and do well you're kind of the exception and not the rule."
Ms Wang is also a highly accomplished musician.
The two other recipients for 2014 were University of Otago politics student Benjamin Abraham and University of Canterbury mechanical engineering student Hamish Tomlinson.
