Minister for Women Julie Anne Genter is calling on women across the country to celebrate the 125th anniversary of New Zealand women getting the vote and to spark debate in their workplaces.
And she says the fact the anniversary falls in the same year as Jacinda Ardern's pregnancy is also a victory.
"I think it is incredible that it coincides with us having our youngest-ever female Prime Minister who is going to give birth in office," Genter said.
"I think that is a wonderful symbolic victory for women."
New Zealand women won the right to vote on September 19, 1893, the first country in the world, and they voted for the first time on November 28 that year.
