Heretaunga Marae Unite to Restore Health of Paritua Karewarewa Stream

Two marae in the Heretaunga region are leading a collaborative effort to revitalise the health of Paritua Karewarewa, a significant spring-fed stream near Bridge Pā in Hastings. Korongata Marae and Mangaroa Marae have reaffirmed their commitment to the waterway, which has long sustained local hapū but now faces challenges including reduced water flows and dry periods. Supported by the Taiao Directorate of Ngāti Kahungunu Iwi Incorporated, the project seeks to blend traditional Māori knowledge with scientific research to ensure the awa thrives for future generations. On 30 July 2026, Waatea News reported that the marae recently hosted a two-day wānanga to review over five years of environmental monitoring data. The event brought together hapū members, environmental scientists, local landowners, and iwi specialists. During the fieldwork phase, participants visited multiple monitoring sites to observe stream conditions and habitat quality. The technical analysis confirmed that while the stream gains flow in its upper reaches, it loses significant volume downstream due to ground seepage, while water quality changes were noted where the stream intersects with other sources. Beyond just measuring flow, the monitoring programme tracked vital ecosystem health indicators such as dissolved oxygen, pH levels, and water clarity. Organisers noted that the lived experiences of whānau, who have observed the stream’s changes over decades, are being validated by this scientific data. This dual approach provides a robust foundation for future discussions regarding groundwater allocation and catchment management in the Hawke's Bay region. Looking ahead, the marae have identified several restoration priorities, including riparian planting, wetland restoration, and the protection of habitats for tuna and native fish. There are also long-term plans to establish a permanent hapū water monitoring station, which would provide rangatahi with opportunities to develop specialised environmental monitoring skills while reconnecting with their ancestral awa.
