Interesting stuff.
Perhaps the ‘red haired, fair skinned people’ were the same as settled East Island, remnants of which Tor Heyerdahl met and described in the book, Aka Aku.
Māori pā (fort)[edit]The Māori name Maungakiekie means "mountain of the kiekie vine".[4] Māori also knew it as "tōtara that stands alone".[3] The mountain and its surrounds were home to the Te Wai ō Hua tribe from the early 1700s and probably before that time. Other Māori tribes in the Auckland area can also trace their ancestry to the mountain.
Maungakiekie was the largest and most important Māori pā in pre-European times. The cone and its surroundings are estimated to have been home to a population of up to 5,000.[5] At this time, the Nga Marama chief Kiwi Tamaki held the pa and used its strategic placement to exact tribute from travellers passing from Northland to the rest of the North Island through the rich isthmus. Its position between the Waitemata Harbour to the east (opening upon the Pacific Ocean) and the Manukau Harbour to the west (opening onto the Tasman Sea) offered a wide variety of seafood from the two harbours. The volcanic soil on the scoria cone was highly fertile, and the inhabitants terraced the slopes extensively. The hill was relatively easy to defend from raiding parties from other tribes due to its steep sides and imposing palisades. Waiohua occupation of the Māori pā ended around 1740-1750 AD when they were defeated in a war against the invading Ngati Whatua-o-Kaipara [6] The pā was abandoned around 1795 AD with the death of Te Taou leader Tuperiri [7]

I'm not the one who's going to argue with the population of 5,000 natives who built this.
