Waitangi Day is the national day of New Zealand, and commemorates the signing, on 6 February 1840, of the Treaty of Waitangi. Ceremonies take place at Waitangi, Northland to commemorate the signing of the treaty, which is regarded as New Zealand's founding document. The day is observed annually and is designated a public holiday, unless 6 February falls on a Saturday or Sunday, when the Monday that immediately follows becomes the public holiday.
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 Politicians are usually granted speaking rights, but on occasion, the privilege has been withdrawn, as with Leader of the Opposition Helen Clark in 1999,[19] Prime Minister John Key in 2016 (when one faction indicated it would even block him from entering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.
Some marae use the day as an open day and an educational experience for their local communities, giving them the opportunity to experience Māori culture and protocol, or as an opportunity to explain where they see Māori are and the way forward for Māori in New Zealand. Commemorations are largely muted in comparison to those seen on the national days of most countries. There are no mass parades or firework displays, nor truly widespread commemorations. At Government House in Auckland, citizenship ceremonies are usually held. As the day is a public holiday, and coincides with the warmest part of the New Zealand summer, many people take the opportunity to spend the day at the beach – an important part of New Zealand culture.
