Tuahiwi is the modern day primary domicile of Ngāi Tūahuriri hapū of Ngāi Tahu. In 1831, prior to European settlement, this pā, and the main Kaiapoi Pā nearby had been attacked by Te Rauparaha in a revenge raid (utu). Following a protracted siege which saw Kaiapoi Pā razed and subsequently abandoned, Tuahiwi became the central Ngāi Tūāhuriri pā. The site was reserved for Māori in 1848 by Walter Mantell following the signing of Kemp's Deed. Meanwhile, a new European settlement arose along the banks of the north branch of the Waimakariri River, named Kaiapoi.
Development
The carved meeting house Tūtekawa that almost burnt down in 1870 succumbed to fire in 1879. Significant colonial developments included the establishment of a Māori mission, which included a church, Saint Stephen's, built in 1867 with its foundation stone having been laid by Governor George Grey on his visit to the settlement.
In 1890, Tuahiwi was described as having a neat village of Māori residences. The old whare had been replaced by fenced cottages with gardens. A school, the Anglican church and country meeting hall functioning as a wharenui, were in the centre of the community. The Native Land Court used the hall from time to time.
Events
In 1900 the Tuahiwi hall was used as a base by D Company of the 1st North Canterbury Mounted Rifle Battalion, a volunteer unit. The Mounted Rifles included Tuahiwi Māori who protested to the Premier Richard Seddon in 1901 on being refused permission to fight in the Second Boer War .
The Tuahiwi statistical area covers 22.71km2 (8.77sqmi). It had an estimated population of 1,000 as of June 2025, with a population density of 44 people per km2.
