The Waitangi Tribunal and Crown lawyers will be shown pa sites razed when British troops retaliated for Maori sacking Kororareka in 1845.
Up to 200 people will tour the the Bay of Islands on the Fullers boat, Dolphin Seeker, when the second week of stage two of the tribunal's Te Paparahi o Te Raki inquiry into northern Maori Treaty grievance claims starts on Monday.
The boat trip will focus on the claims of Nga Hapu o te Tautai Moana (Bay of Islands) and in particular the claims of Ngati Manu hapu at Karetu, Te Kapotai at Waikare and Ngati Kuta/Patu Keha on the Te Rawhiti peninsula.
These claims include issues such as war atrocities, crooked land dealings and Crown purchases.
Following Hone Heke's bloodless attacks on the flagpole at Kororareka, the Northern War began in earnest with the invasion of the town on March 11, 1845.
