2.2 A Layered Cultural Landscape

The name Te Ara Tupua
references the Project’s
association with Ngāke and
Whātaitai, the Tupua of Te
Whanganui a Tara.
As recorded in the Project Cultural Impact Assessment by Morrie Love, this
is an area with strong association with the Te Atiawa hapu of Ngāti Te Whiti,
Ngāti Tawhirikura, and others of Te Atiawa nui tonu particularly those who were
connected to Pito-One Pa and Ngā Ūranga Pā. The area has a rich and layered
cultural history stemming from the creation of Aotearoa. This narrative and the
Kaitiaki Strategy principles developed for the Project to realise its mana and mouri
underpin the overall vision and design themes for the Project.

Early Māori History

“During the 1820s and 1830s, members of Te Āti Awa and other tribes left their         Figure 2.43 Migration of Te Āti Awa and other tribes from Taranaki to Kapiti coast and Wellington harbour, Isthmus
ancestral home in Taranaki and travelled south in four great migrations, finally
reaching the Kapiti coast and Wellington Harbour. In 1832 the Te Āti Awa people
from Ngāmotu moved south in considerable numbers. This migration was known as
Te Heke Tamateuaua. Ngāti Tawhirikura were led by Tautara, Ruaukitua, Ngātata-i-
te-rangi, Te Wharepōuri and Hēnare Te Keha. Also in the migration were the people
of Ngāti Mutunga, led by the chiefs Rangiwāhia, Hautohoro, Onemihi, Te Ito from
Waitara and Te Puponga (William Keenan) from New Plymouth.

After their journey from Taranaki, Te Āti Awa people from Ngāmotu settled first at
Waikanae. The hapū (sub-tribe) Te Mana of Ngāti Mutunga were living at Pito-One
(Petone) just north of Wellington, having arrived in a previous migration from
Taranaki. They invited the Ngāmotu chiefs Te Puni, Te Wharepōuri, Te Matangi
and his son Te Manihera Te Toru to settle with them there, since they were close
kin. While the Ngāmotu people were in the Wairarapa, the situation along the Kapiti
coast had deteriorated because of pressures on land, and old rivalries. Haowhenua,
a long-running and inconclusive battle in 1834, saw another Taranaki migration,
known as Paukena, arrive from Waitara. These Te Āti Awa people were led by Te
Rangitāke (also known as Wiremu Kīngi). 23

Honiana Te Puni and Te Wharepōuri

“Honiana Te Puni was a Te Āti Awa chief of high lineage who was
descended from Takarangi and Rau-Mahora. His own father was
Rerewha-i-te-Rangi, son of Aniwaniwa and Tawhirikura, the originators
of the Tawhirikura subtribe of Te Ati Awa. His mother was Te Puku. Te
Puni lived at Pukeariki Pā, New Plymouth, and took part in the successful
defence of Otaka against the Waikato. Later he accompanied the followers
of Wharepōuri, Rawa-Kitua, and Ngatata, southward in the
“heke” Tama te Uaua.

His people settled in the neighbourhood of Cook Strait or Whanganui-a-
Tara and, by about 1832, he was fully established at his pa on the beach
at “Pito-One”, now known as Petone. In 1840 Te Wharepōuri and Te Puni
welcomed the first New Zealand Company pioneers to Port Nicholson.
Soon after, Te Puni was one of the signatories of the Treaty of Waitangi
and the deed of purchase of the land about Wellington. He died on
5 December 1870 and was accorded a State funeral with full military
honours24.

Te Wharepōuri was born in Taranaki, the son of Te Whiti and Hine-te-Uru.
He was a grandson of Te Whitikatura by his principal wife, Rongouaroa,
and was thus a senior chief of the Ngāti Tawhirikura branch of Te Āti Awa,
being senior to his cousins Makore Ngātata-i-te-rangi and Te Puni. He was
also closely related to Te Whiti, the prophet of Parihaka.

Te Wharepōuri fought at Motunui in 1822 and in the defence of
Pukerangiora. In 1826 he served with Whatanui’s taua against the Ngāti
Kahungunu. He was one of the Te Āti Awa party when Te Karawa was
killed at Pūtiki Pā by the Ngāti Ruanui and joined the party of Waikatos
under Te Waharoa, Tarapipipi, and Naera, whom Ngātata summoned to
avenge this insult.

Te Wharepōuri’s last years were burdened by serious illness and he died
at Ngā Ūranga on 22 November 1842. On his deathbed he is said to have
