Beaumont said New Zealanders were right to be proud of being the first country to give women the vote.
But she said there was also a sense from some people that the work was now done.
"If you look at any real measure like women's economic independence, issues of safety and violence, then you see there's still a long way to go."
Minister for Women Paula Bennett agreed there was still a need for change.
She cited the top two issues for women as being the pay gap, and that women were disproportionately the victims of domestic violence.
Bennett said Suffrage Day coming so close to the election was a reminder of how women's involvement in politics had changed.
"In particular this election, which is a close race and has got a lot of people talking about politics.
"I watch women's participation, and the way that they vote, and times have really changed.
"It used to be that many women used to vote the same as their husband, or wouldn't tell their husband because their vote was private and they didn't want to be influenced.
"You can see quite a different society now and I think that's really exciting and important."
