TRC monitoring data sourced from LAWA (Land Air Water Aotearoa) and Taranaki Regional Council State of the Environment reports. MCI scores shown are 5-year medians using national scoring methods. Proposed sites (amber markers) have no baseline data — these are recommended student survey locations. The Huatoki Metro Plaza daylighting site is particularly significant as the stream is being uncovered for the first time in nearly a century (April 2026).
