Ngāti Wairangi (South Island iwi)

Ngāti Wairangi was a Māori iwi (tribe). Its rohe (tribal area) covers the West Coast of the South Island of New Zealand.

It was the last Waitaha tribe to be integrated into Ngāi Tahu, the principal tribe of the South Island today. The West Coast was commonly known as Te Tai Poutini, named for a Taniwha who protected the people and pounamu of the region. They held control over Arahura, a settlement known for its deposits of pounamu (greenstone), which led to conflict as Ngāi Tahu conquered the South Island in the 1600s and 1700s.
