The Treaty of Waitangi was first signed on 6 February 1840 on the grounds of James Busby's house—now known as Treaty House—at Waitangi, in the Bay of Islands. The treaty was signed by representatives acting on behalf of the British Crown and, initially, about 45 Māori chiefs. Over the course of the next seven months, copies of the treaty were toured around the country to give other chiefs the opportunity to sign. The signing had the effect of securing British sovereignty over the islands of New Zealand, which was officially proclaimed on 21 May 1840.
Commemorations at Waitangi usually commence the previous day, 5 February, at the Ngāpuhi marae Te Tii, when political dignitaries are welcomed onto the marae and hear speeches from the local iwi. These speeches often deal with the issues of the day, and vigorous and robust debate occurs. Politicians are usually granted speaking rights, but on occasion, the privilege has been withdrawn, as with Leader of the Opposition Helen Clark in 1999,[19] Prime Minister John Key in 2016 (when one faction indicated it would even block him from entering the marae), and Prime Minister Bill English in 2017. In 2018, Jacinda Ardern was the first Prime Minister to attend the ceremony in three years.
At dawn on Waitangi Day, the Royal New Zealand Navy raises the New Zealand Flag, Union Flag and White Ensign on the flagstaff in the treaty grounds. The ceremonies during the day generally include a church service and cultural displays such as dance and song. Several waka and a navy ship also re-enact the coming ashore of Governor Hobson to sign the treaty. The day closes with the flags being lowered by the Navy in a traditional ceremony.
