Frayed flags representing the Whanganui River marae fluttered in the wind as the ministers and officials of the Crown were welcomed on to Ruaka Marae in Ranana.
They were there to sign the Whanganui River Deed of Settlement, which marks the end of 10 years of on-and-off negotiation and more than a century of litigation between Whanganui River hapu and iwi, and government.
The settlement will recognise the values of the relationship between the iwi and the river, by recognising the river as Te Awa Tupua, and giving it legal personality status with its own rights.
Crowds of people flooded the marae on Tuesday, with some travelling from near and far to witness the historic occasion.
Marama Allen, a teacher at Wanganui High School, said she considered the event a "dream come true" for her ancestors.
