The Mawaihakona Stream (also known as Māwai Hākona Stream) is a small watercourse in Upper Hutt, in the North Island of New Zealand. The stream begins at a spring in Trentham Memorial Park and drains the western side of the Hutt Valley from Trentham to Heretaunga, flowing into the Hutt River north of the Silverstream bridge. An environmental restoration project has been underway since 2002 with the aim of restoring the health of the stream. Over 10,000 trees have been planted on the banks of the stream, and the stream bed has been progressively cleared of invasive exotic species. The project has been recognised with several environmental awards.
