To conservator Fergus Clunie, Pouērua is a terraced and fortified volcano which still physically and spiritually dwarfs the surrounding Pākehā pastoral land as it once commanded a Polynesian horticultural landscape. Its statistics are impressive. The cone pās central defended perimeter stretches for 600 m.
East Polynesians favoured the coast, where foraging and travel were easier, but made exceptions for areas such as the inland Bay of Islands, with its rich soils. Over time, Auckland University archaeologists tell us, the sparse open settlements on the Taiāmai Plains thickened into a maze of forts, gardens and hamlets. The first settlements were small and scattered (70% of kāinga [undefended settlements] had only one dwelling and just 2% had more than seven), but that changed. Between 1450 and 1600 peripheral pā appeared around the mountain. Pā defended territory but they also symbolised power and authority within an increasingly complex society. Along a 9-km stretch of rich, friable volcanic soil on the Taiāmai Plains, archaeologists have counted more than 300 kāinga.
Pouēruas last Māori occupiers were Ngāti Rāhiri. This Ngāpuhi hapū supported Hongi Hika in the bloody Musket Wars. Its survivors left here about 1860, no match for missionary families coveting land. In recent decades developers equally grasping shadows have threatened one of New Zealands best-preserved and most studied Polynesian/Māori landscapes.
