A city on fifty volcanoes

Two harbours, a narrow neck of land, and the portage that made it worth having.

What you should be able to do after this: Explain why the Tāmaki isthmus was so contested, and how a volcanic field became a city's terraced heritage and its quarries.

Start with geography

Two seas, one narrow neck

Auckland sits on an isthmus about a kilometre and a half wide at its narrowest. On one side is the Waitematā Harbour, opening east to the Pacific. On the other is the Manukau, opening west to the Tasman Sea. Two different oceans, a short walk apart.

For people travelling by canoe that is enormously valuable: instead of sailing around the top of the North Island, you carry your waka across the neck. The portage routes across the isthmus were the reason this place mattered, and the Māori name Tāmaki Makaurau is generally rendered as Tāmaki desired by many — a description of how contested it was.
