The commemorations will continue today with tours of the battle sites at Ohaeawai and Ruapekapeka, while tomorrow the focus switches to Russell with a sunrise flag-raising ceremony; an 8am procession from the wharf to Christ Church, where much of the first day's battle raged; a remembrance service; and a powhiri at Haratu Marae followed by a handover to the region hosting next year's event.
Organising committee member Pita Tipene, of Ngati Hine, said it had taken ''an extraordinarily long journey'' to achieve official recognition of the New Zealand Wars.
Ever since the battles people had remembered in their own ways but pressure for a national day came to a head in 2014 when students at Otorohanga College started a petition, gathered 13,000 signatures and delivered it to Parliament.
''Only then did the government of the day take notice,'' he said.
The Government didn't declare a state holiday but it did designate a remembrance day, October 28, and put up $4 million over four years with Northland chosen to host the first commemorations.
''It's evident a lot of people around our country don't know our history. We tend to focus on Anzac Day but we need to remember all of our past, to inform our future.''
Mr Tipene said he was keen to see the New Zealand Wars included in the school curriculum so all children could learn about them.
Those attending the commemorations include groups from Tainui-Waikato, Tauranga Moana and Taranaki, the entire roll of an Opotiki school, and students from Otorohanga College.
