Internal Affairs Minister Chris Tremain says the decision to relocate the Treaty of Waitangi was made after consultation with Maori groups.
The country's founding document is housed at Archives New Zealand in Molesworth Street in Wellington and will be moved to the newly refurbished National Library near Parliament next year.
Mr Tremain says he hopes the refurbishment will encourage more people to visit the library and view Te Tiriti o Waitangi.
He says Maori groups were consulted, including local iwi Taranaki Whanui ki Te Upoko o Te Ika, before the decision to move the Treaty was made.
Mr Tremain says it was important to talk with the Wellington iwi because they are the guardians of the Treaty. Discussions were also held with the Maori Party and advisory group Te Komiti Maori, whose members represent a number of iwi in New Zealand.
Te Komiti Maori provides independent advice on Maori affairs to the chief executive of the National Library.
Mr Tremain says all Maori groups consulted are supportive of the decision to move the document.
