In anticipation of a decision to exhibit the document in 1990 (the sesquicentennial of the signing), full documentation and reproduction photography was carried out. Several years of planning culminated with the opening of the climate-controlled Constitution Room at the National Archives by Mike Moore, Prime Minister of New Zealand, in November 1990. It was announced in 2012 that the nine Treaty of Waitangi sheets would be relocated to the National Library of New Zealand in 2013. In 2017, the He Tohu permanent exhibition at the National Library opened, displaying the treaty documents along with the Declaration of Independence and the 1893 Women's Suffrage Petition.
