The Wairau Plain and its surrounding sounds, ranges and river valleys have been a centre of Māori settlement in the South Island for centuries. The word Wairau itself comes from ngā wai-rau o Ruatere — the hundred waters of Ruatere — a reference to the network of rivers, wetlands and estuaries that made this region one of the most resource-rich in Aotearoa. Long before Blenheim existed, this landscape supported successive generations of iwi, and the events of the nineteenth century here shaped New Zealand’s early colonial history in lasting ways.

Wairau Bar: New Zealand’s Earliest Settlement
At the mouth of the Wairau River, where the river meets the sea near Rarangi, lies Wairau Bar — one of the most significant archaeological sites in New Zealand. The earliest known human inhabitants of the Marlborough region settled here in the thirteenth century, leaving behind evidence of a community sustained by the extraordinary natural resources of the area: moa, seals, fish and shellfish. The Wairau Bar excavations have produced some of the oldest and most complete skeletal remains of early Polynesians found anywhere in the country.
The site is significant not just archaeologically but culturally. Rangitāne o Wairau iwi are the descendants of those early inhabitants, and they maintain a strong connection to the bar as an ancestral site. The remains and artefacts uncovered here are held as taonga.
Rangitāne o Wairau
Rangitāne became the principal iwi of the Wairau region through a series of migrations in the early sixteenth century, led by the chief Te Huataki. Arriving via the Marlborough Sounds from the Wairarapa coast, Rangitāne merged with the iwi already present — including Ngāi Tara and Ngāti Māmoe — largely through intermarriage rather than conflict, and established themselves as the dominant people of the Wairau Plain.
Rangitāne managed the landscape intensively. The name Wairau reflects the importance of the waterway network — estimated at around 18 kilometres of natural and modified channels — which supported cultivation, fishing and the harvesting of waterfowl including eels and �ųtangitangi (paradise shelduck). This was a carefully managed food system, not a wild landscape.
Ngāti Toa and Te Rauparaha
In the early nineteenth century, the balance of power in the South Island shifted dramatically with the arrival of Ngāti Toa Rangatira from the Kāpiti Coast. Led by the formidable chief Te Rauparaha, Ngāti Toa expanded south across Cook Strait, defeating Rangitāne in the Wairau Valley by the early 1830s and establishing authority over the northern South Island.
Te Rauparaha based himself at Kāpiti Island but held significant influence over the Wairau, Pelorus and Sounds areas. His nephew Te Rangihaeata was particularly active in the Marlborough region. Ngāti Toa’s presence here set the stage for the conflicts that would follow as British colonisation began in earnest.
The Wairau Affray, 1843
The Wairau Affray of 17 June 1843 is one of the defining events in New Zealand’s colonial history. A party of Nelson settlers and police, led by Captain Arthur Wakefield, attempted to arrest Te Rauparaha and Te Rangihaeata at Tuamarina — about 10 kilometres north of present-day Blenheim — over a disputed land survey. The confrontation ended in violence: 22 settlers and four Māori were killed, including Te Rangihaeata’s wife Rongo.
The incident was widely condemned at the time by Governor Robert FitzRoy as the fault of the settlers, and for many years it was the focus of intense debate about sovereignty, land purchase and the rights of Māori under the Treaty of Waitangi. A memorial to the European dead stands in the hilltop cemetery at Tuamarina on Cotterill Street, with sweeping views north over the Wairau Valley — it remains a sobering place to visit.
Māori Heritage in Blenheim Today
Eight iwi hold mana whenua in Te Tauihu (the top of the South Island): Rangitāne o Wairau, Ngāti Toa Rangatira, Ngāti Rārua, Ngāti Kuia, Ngāti Koata, Ngāti Tama ki Te Tau Ihu, Te Ātiawa o Te Waka-a-Māui, and Ngāti Apa ki te Rā Tō. All have historical connections to the Marlborough region.
The Marlborough Museum in Blenheim holds a collection of Māori taonga and displays on the Wairau Bar excavations and Wairau Affray. For deeper engagement with the history of the region, the museum is the most accessible starting point in town. The Wairau Bar site itself is on the coast near Rarangi and is accessible, though the archaeology is not on display at the site.
