The Maraetaha River is a river in the Gisborne District of New Zealand's North Island, flowing into the Pacific Ocean south of Muriwai and Young Nick's Head. A key access point for paddlers is located at or near Maraetaha River Bridge No.1 on State Highway 2, approximately one kilometer south of Gisborne. This bridge area provides a logical put-in or take-out point, with a sharp turn-off to the left immediately after crossing the bridge heading south. The river's character is coastal, with its lower reaches leading to Māpiri Beach, suggesting a mix of freshwater and tidal influence near its mouth. The surrounding area features the Māpiri Track, a walking trail that connects to the river and beach, indicating the presence of native bush and coastal scenery. The river's proximity to SH2 makes it relatively accessible from Gisborne. The river's setting offers a connection to the coastal environment of the Tairāwhiti region.
