Archives New Zealand (in Māori: Te Rua Mahara o te Kāwanatanga) is the National Archives of New Zealand, with responsibility for the record of government. This includes regulation of information management in the public sector, management of the national archival collection, and leadership of the archives sector.^[1] Since 1 February 2011 it has been part of the Department of Internal Affairs. Before 1 February 2011 Archives New Zealand was a separate government department.^[2]

The Public Records Act 2005 sets the framework for contemporary recordkeeping across government in New Zealand and Archives New Zealand works with government agencies to administer the Act. The Public Records Act 2005 greatly expanded the role of Archives New Zealand and the powers of the Chief Archivist.^[3] The organisation now has a leadership role for recordkeeping throughout central and local government.

Archives New Zealand holds more than 100 kilometers of New Zealand government records dating from the early 19th to the early 21st century. Records held include the originals of the Treaty of Waitangi, government documents, maps, paintings, photographs and film. Researchers can search descriptions of the records online, via the Archway finding aid.

In May 2017, a new permanent archive exhibition He Tohu, opened at the National Library of New Zealand building on Molesworth Street, Wellington. He Tohu is an exhibition of three of New Zealand's most significant constitutional documents. The documents remain in the care of the Chief Archivist under the Public Records Act 2005. The documents are:

• 1835 He Whakaputanga o te Rangatiratanga o Nu Tireni - the Declaration of Independence of the Chiefs of New Zealand (the Declaration);
• 1840 Te Tiriti o Waitangi - the Treaty of Waitangi; and
• 1893 Women's Suffrage Petition - Te Petihana Whakamana Pōti Wahine.

The exhibition was developed from mid-2014 until May 2017. It provides an award winning document room containing the latest exhibition technology and a surrounding interactive space for visitors to learn about the documents and the people who signed them. He Tohu is accompanied by an education and outreach programme including an online component to make it accessible for those not Wellington-based. He Tohu is presented by Archives New Zealand and the National Library of New Zealand, both of which are part of the Department of Internal Affairs. The exhibition is set to run for 25 years.^[4]
