About 50 meetings were held from February to September 1840 to discuss and sign the copies, and a further 500 signatures were added to the treaty. While most did eventually sign, especially in the far north where most Māori lived, a number of chiefs and some tribal groups ultimately refused, including Pōtatau Te Wherowhero (Waikato iwi), Tuhoe, Te Arawa and Ngāti Tuwharetoa and possibly Moka 'Kainga-mataa'. A number of non-signatory Waikato and Central North Island chiefs would later form a kind of confederacy with an elected monarch called the Kīngitanga. (The Kīngitanga Movement would later form a primary anti-government force in the New Zealand Wars.) While copies were moved around the country to give as many tribal leaders as possible the opportunity to sign, some missed out, especially in the South Island, where inclement weather prevented copies from reaching Otago or Stewart Island. Assent to the treaty was unanimous in Kaitaia, as well as possibly the Wellington to Whanganui region, but there were at least some holdouts in every other part of New Zealand.
