The government has bought Kate Sheppard's former home in Christchurch for more than $4 million.
The Ilam villa will be used as an educational centre for university research projects and school history trips, and made available for public access and events.
It was bought for $4.5 million at the start of September and it will be managed by Heritage New Zealand Pouhere Taonga in partnership with the University of Canterbury.
The house was the headquarters for Ms Sheppard's suffragist campaign, and the location where her 270-metre petition was glued together, helping win the women's right to vote on this day in 1893.
Minister for Arts, Culture and Heritage Jacinda Ardern said New Zealanders take pride in being the first country in the world where women voted.
"This is the home where that crucial progress centred, making it of huge significance both locally, nationally and internationally," she said.
Greater Christchurch Regeneration Minister Megan Woods said the government had a joint vision with Christchurch City Council to showcase the work of Kate Sheppard and profile other New Zealand women who have brought about social change.
"Purchasing and developing Kate Sheppard's house as a public asset allows us not only to make it accessible to the public all year round, but we're able to conserve its unique heritage values for future generations," she said.
Nicola Jackson, Heritage New Zealand deputy chief executive, told Morning Report there was a great celebration in Christchurch at the news.
She said the house was incredibly important to New Zealand history.
"This house hasn't come on the market for some 33 years so it was a great opportunity given there's a 125 years since women received the right to vote.
"It was perfect timing to acquire this particularly significant place for the nation," Ms Jackson said.
Ms Jackson said the house will now be managed by Heritage New Zealand and will be opened to the public.
The government first expressed interest in the house in October last year, when it went up for auction and later failed to sell.
The Clyde Road property had a full independent valuation of $4.1 million in 2018.
