"A lack of starch in the samples indicated that the sample deposits hadn't been used for cultivation, or for cooking starchy crops like kumara and fern root.
"This suggested that clearance of the forest had taken place at an early stage of settlement before human land use had begun and that it was therefore reasonable to assume that it was an early site."
However, the question of whether the people who cleared the forest near Kamo were the first generation of Polynesians who settled in New Zealand remains unanswered.
"It's very difficult to say with certainty whether they were the first generation or not. It's fair to assume, though, that they would have been some of the earliest settlers in the area." Fresh water nearby may have attracted the settlers there, Dr Phear said.
"It may not be obvious today, but two late 19th-century plans indicate that there was a swamp in the area at that time next to the Otangarei Stream. Local traditional histories of the Ngaitai hapu also speak of a lake in the area of the present Kamo golf course."
She and her team hoped to investigate the site further to learn more about the historic landscape.
Te Parawhau representative Te Ihi Tito was excited to hear the news.
"It probably relates back to the initial clearing of the forest for gardening in Kamo," he said.
