Understanding Iwi and Hapū

Iwi and hapū are the fundamental social units of Māori society, representing a shared identity rooted in ancestry, land, and collective responsibility. The terms are often translated as "tribe" and "sub-tribe," but these English words don't fully capture their Māori meaning. An iwi is a large kinship group that traces its descent to a common ancestor, while a hapū is a smaller unit within an iwi, typically descended from a more recent common ancestor.

These structures have provided the framework for Māori social organization for centuries, determining rights to land and resources, responsibilities to the community, and connections to ancestral sites. Today, iwi and hapū continue to play vital roles in Māori identity, cultural practice, and political representation.

The Major Iwi of New Zealand

There are over 100 iwi throughout Aotearoa, each with its own history, territory, traditions, and dialect. The major iwi are often grouped by region, with the largest tribes concentrated in the North Island where Māori settlement was initially densest. The following are some of the most significant iwi:

Northland

Ngāpuhi

The largest iwi in New Zealand, based in the Hokianga, Bay of Islands, and Whangārei regions. Ngāpuhi traces its ancestry to the great waka Mataatua and is known for its strong warrior traditions. The iwi played a significant role in early contact with Europeans.

Ngāti Whātua

Based in the Kaipara Harbour area and Auckland region. Ngāti Whātua is historically significant as the iwi that invited William Hobson to establish the colony of New Zealand, and whose leaders signed the Treaty of Waitangi at Waitangi.

Ngāi Takoto

A smaller iwi based in the far north, with a strong connection to the land around Te Kaita and Mangamuka. Ngāi Takoto is one of the northern tribes descended from the waka Mataatua.

Waikato & King Country

Waikato

One of the largest iwi, based along the Waikato River. Waikato is associated with the great waka Tainui and is known for its strong leadership traditions. The iwi played a central role in the Kingitanga (Māori King) movement.

Ngāti Maniapoto

Based in the King Country region, Ngāti Maniapoto is a major iwi descended from the waka Tainui. The iwi is known for its strong advocacy and the famous orator Te Whiti o Rongomai.

Ngāti Ruanui

Based in the Taranaki region, with strong connections to the land between the Waitara and Pātea rivers. The iwi has a rich cultural heritage and is active in contemporary Treaty settlements.

Bay of Plenty & East Coast

Ngāi Tahu

The principal iwi of the South Island, descended from the waka Tahu. Ngāi Tahu was the fourth major tribe to settle in the South Island and has become one of the largest and most successful iwi in terms of tribal enterprise and governance.

Te Arawa

A confederation of iwi descended from the crew of the waka Arawa, based in the Bay of Plenty. Te Arawa includes tribes such as Te Arawa proper, Tūwharetoa, and Te Āti Awa. Known for their expertise in carving and weaving.

Ngāti Porou

Based on the East Coast from Pōrangahau to Te Araroa. Ngāti Porou traces its ancestry to the waka Horouta and is one of the largest and most influential iwi in the eastern North Island.

South Island

Ngāi Tahu

The predominant iwi of Te Waipounamu (South Island), with territory spanning from Kaikōura to Stewart Island. Ngāi Tahu settled in the South Island between 1577-1677 and has a strong connection to mahika kai (customary food gathering places).

Ngāti Mamoe

An iwi that historically occupied much of the South Island before being absorbed into Ngāi Tahu through intermarriage and conquest. The name survives as a significant part of South Island history.

Structure of Māori Society

Māori society is organized in a hierarchical structure that connects individuals to their ancestors, land, and community. Understanding this structure helps explain how Māori social and political organization worked traditionally and how it continues today.

Iwi (Tribe)

The largest unit, tracing descent to a common ancestor, often the captain of a great migration waka. Iwi have their own territory, history, and traditions.

Divided into

Hapū (Sub-tribe)

A smaller unit within an iwi, typically descended from a grandparent or great-grandparent. Hapū have their own marae and elect their own chiefs.

Composed of

Whānau (Extended Family)

The basic unit of Māori society, including grandparents, parents, children, and extended relatives. Whānau share responsibility for each other's wellbeing.

Led by

Rangatira (Chief)

Leaders who derive their authority from whakapapa (ancestry) and are recognized for their wisdom, generosity, and leadership abilities.

Rangatira and Tohunga

Traditional Māori society recognized two categories of leaders: rangatira (chiefs) and tohunga (experts/specialists). While both held important positions, their roles were distinct and complementary.

Rangatira

Political and Social Leaders

Rangatira are chiefs who lead their people through inherited authority (mana) and personal qualities. A rangatira's mana comes from their whakapapa (ancestry) and their demonstrated leadership, wisdom, and generosity. Good chiefs were expected to:

  • Make decisions that benefit their people
  • Be generous with their resources
  • Speak eloquently at gatherings
  • Maintain relationships with other tribes
  • Uphold the tikanga (customs) of their people

Tohunga

Religious and Technical Experts

Tohunga are specialists in particular fields, from religious knowledge to carving, healing, navigation, or warfare. Their expertise gives them authority in their specific domains. Traditional tohunga included:

  • Tohunga whaikōrero (oratory experts)
  • Tohunga tā moko (tattoo specialists)
  • Tohunga rongoā (healers/herbalists)
  • Tohunga whakairo (master carvers)
  • Tohunga kōrero (storytellers/historians)

Pepeha and Whakapapa

Pepeha are the traditional Māori way of introducing oneself, stating one's connection to the land and ancestors. A pepeha typically includes references to mountains (maunga), rivers (awa), ancestors (tupuna), and tribal affiliations (iwi/hapū). When someone says their pepeha, they are essentially saying "this is who I am and where I come from."

Components of a Pepeha

A traditional pepeha includes several key elements:

  • Ko (This is) - Introduction of significant geographic features
  • Nō (From) - Statement of ancestral connection to a place
  • Ko (These are) - Introduction of ancestors or notable figures
  • Ko (This is) - Statement of iwi and hapū affiliation

Example: "Ko Mauao te maunga, ko Tauranga te moana. Ko Ngāti Ranginui te iwi. Ko [Name] ahau." (Mauao is the mountain, Tauranga is the sea. Ngāti Ranginui is the tribe. I am [Name].)

Maunga (Mountain) Awa (River) Moana (Sea)

Key geographic features in pepeha: maunga, awa, and moana

Iwi Governance Today

Contemporary iwi are governed by structures that blend traditional authority with modern legal requirements. Iwi organizations, often called rūnanga or trust boards, are responsible for representing iwi interests, managing tribal assets, and advocating for the wellbeing of their members.

Iwi Organizations

Most major iwi have established formal organizations to represent their interests. These bodies typically have elected or appointed committees, constitutions, and governance frameworks. Their functions include:

  • Representing iwi in Treaty of Waitangi settlement negotiations
  • Managing tribal assets and investments
  • Providing services to iwi members (education, health, social support)
  • Advocating on policy issues affecting iwi interests
  • Preserving and promoting te reo Māori and cultural traditions
  • Environmental management of traditional territories

Treaty Settlements

Since the 1990s, many iwi have negotiated settlements with the Crown to address historical grievances arising from breaches of the Treaty of Waitangi. These settlements typically include financial compensation, return of cultural sites, and formal Crown apologies. Ngāi Tahu, whose settlement was finalized in 1998, has become a model for successful iwi governance and commercial development.

Major Iwi by Waka

The great migration waka that brought Māori ancestors to Aotearoa serve as a key organizing principle for iwi identity. Each major waka is associated with a confederation of iwi and hapū who trace their descent to that vessel and its captain.

Tainui

Landed at Kawhia under Hoturoa. Associated iwi include Waikato, Ngāti Maniapoto, Ngāti Ruanui, and other tribes of the western North Island.

Te Arawa

Landed at Maketu under Tama-te-kapua. Associated iwi include Te Arawa confederation, Tūwharetoa, Te Āti Awa, and others in the central North Island.

Mātaatua

Landed at Whakatāne under Toroa. Associated iwi include Te Arawa (some lines), Ngāti Awa, Whakatōhea, and eastern Bay of Plenty tribes.

Tokomaru

Landed at Ōtaki under Rua-pū-titi. Associated iwi include Rongomaiwahine, Ngāti Raukawa, and tribes of the lower North Island.

Ngātokimatawhaorua

A legendary waka of Kupe, associated with the northern tribes. While some iwi claim direct descent, its historical details are less documented.

Tāhū

Landed at Kaiwharawhara (Wellington) under Turi. Associated iwi include Ngāti Toa Rangatira, who later migrated to Kapiti Island and the South Island under Te Rauparaha.
