The New Zealand Suffrage Centennial Medal 1993 was established by Royal Warrant on 1 July 1993. It was created to commemorate Women's suffrage in New Zealand and to recognize those New Zealand and Commonwealth citizens who had made a significant contribution to women's rights or women's issues in New Zealand. The medal was only awarded in 1993.

Women's suffrage was an important political issue in the late-nineteenth-century New Zealand. In early colonial New Zealand, as in European societies, women were excluded from any involvement in politics. Public opinion began to change in the latter half of the nineteenth century and after years of effort by women's suffrage campaigners, led by Kate Sheppard, New Zealand became the first nation in the world in which all women had the right to vote in parliamentary elections.
