Celebrations at Waitangi often commence the previous day, 5 February, at the Ngapuhi Te Tii marae, where 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.

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 calling ashore of Governor Hobson to sign the treaty. The day closes with the flags being lowered by the Navy in a traditional ceremony.
