Kumutoto Stream
The Kumutoto Stream (Māori: Kumutoto Awa) is a culverted stream in Wellington, New Zealand. In the 1860s, it was the first stream in Wellington to be culverted. A part of the stream is listed as Wāhi Tūpuna by Heritage New Zealand. The stream begins in the Kumutoto Forest (below Salamanca Road near Victoria University of Wellington), enters a culvert above the Terrace Motorway Tunnel, and flows through underground pipes alongside The Terrace and beneath Woodward Street, before entering Wellington Harbour at Kumutoto Plaza. An art installation by Michel Tuffery, featuring large kina shell sculptures, marks the stream's entrance into the harbour.
