The National Library has various exhibition spaces including the Turnbull Gallery, displaying rare books and ephemera. The highlight is He Tohu (The Signs) exhibition, housing three of NZ's most treasured documents: the 1835 Declaration of Independence of the United Tribes of NZ, the 1840 Treaty of Waitangi and the 1893 Women's Suffrage Petition. Also here is Ngā Taonga Sound & Vision, the national film archive, which presents regular displays at the library.
