Born in rural New Zealand as the oldest of four girls, Helen Clark, New Zealand's former prime minister has promoted increased opportunities for women while paving her own path of success.

From heading a country to running the United Nations Development Programme (UNDP), she has proven her strength of character and determination to improve the lives of others.

Helen Clark developed her keen interest in politics while studying and lecturing in political science at the University of Auckland.

After an extensive parliamentary and ministerial career, she eventually became the first elected female prime minister of New Zealand and the first prime minister to win three consecutive terms, from 1999 to 2008.

Then, in 2009, Helen Clark became the first woman to lead the United Nations Development Programme (UNDP) where she continues to engage in advocacy and development across the globe.
