Among the speakers was Far North Mayor Wayne Brown, who said he looked forward to a new era of partnership and, given the high standard of leadership of Far North iwi, a lift in economic performance benefiting everyone in the district.
Mr Finlayson agreed, saying the signing was a "fantastic opportunity" for regional development, and a turning point for relations between Ngai Takoto and the Crown.
He paid tribute to the resolve and toughness of Ngai Takoto's negotiators, and read the Crown's apology in full, detailing how the iwi had been left virtually landless by 1859 and the on-going effects of that loss.
Mr Marsden accepted the apology and spoke of a new start.
"We accept the challenge of a new dawn, a new beginning, a new future... Enough is enough, let's move forward together," he said.
He hoped the settlement would help turn the Far North's fortunes around and bring its people home from Australia, but the iwi had not been idle while its settlement was finalised. It was already working with councils and the Te Hiku Forum on plans for Northland's economic and social advancement; the next challenge would be better representation for Maori in local government.
Mr Marsden was adamant that the settlement was the best Ngai Takoto could achieve.
"If there was any more to do we'd still be negotiating," he said.
"When you get to a point where you've got all you can get, there's no point turning on your neighbours."
The iwi marked the signing with a three-day celebration which included a sports tournament, kapa haka, a hakari, the announcement of seven academic scholarships and the unveiling of a carved pou at Kaitaia's Te Ahu.
Also present on Saturday were representatives of King Tuheitia, the other Te Hiku iwi, MPs Shane Jones and Mike Sabin, the Northland Regional Council and the Department of Conservation.
