New Zealand is known be the first self-governing region to have given universal suffrage to women. However, during this time, the indigenous people in European colonies had little rights due to the white supremacy movements. Were the Maori women (or men) really given right to vote, and if not, what were the limitations?
Maori women were given the right to vote in 1893, along with Pakeha (non-Maori) women.
Although yes it was common for the indigenous populations of colonised counties to experience voting restrictions, they Treaty of Waitangi in 1840 declared that Maori would be protected as British citizens. There was never the same racial divide, as there was in Australia for example.
In 1852, the New Zealand Constitution Act passed which defined the qualities needed to vote. A voter had to be male, of age and a British subject. Maori were British subjects. However, and this was very significant, voters were illegible if they did not own, lease or live in a house. Maori typically lived communally and so were technically disqualified.
During the 1860s, New Zealand experienced a civil war between certain Maori tribes and the Crown. This influenced policy makers to rethink the Maori vote. The Maori Representation Act in 1867 allowed for special-Maori held seats in Parliament. A defining quality of this Act was that all Maori men over the age of 21 could vote.
Back to your question, Maori women could vote as well as Pakeha women in 1893 because the paper work to allow Maori to vote at all had already been finished.
Interestingly enough, Maori were the first non-whites to be able to vote in Australia, as specified in the Commonwealth Franchise Act 1902.
