Treaty negotiator, Te Oranganui chief executive and former head of the Whanganui River Maori Trust Board Nancy Tuaine sat at the foot of the signing table on the day.
"The signing of our Whanganui River Deed of Settlement, Ruruku Whakatupua, was such an amazing day - a day we have been waiting for over 160 years since the first legislation in the 1850s," she said.
"At our signing on Tuesday, the sun shone on a new chapter, as the iwi across Whanganui joined with the Crown, with non-Maori, and indeed with a distinguished line-up of ambassadors from right across the globe. It signalled a new start in our journey in nationhood; and gave me the courage to know we can create a stronger future."
The signing has also been called a watershed day for Ruapehu District Council (RDC) and its engagement with iwi by Mayor Don Cameron.
He was at the historic event with councillor officers and a district councillor.
