Lake Kaiwai is an alluvial lake in the Northland Region of New Zealand.[1] It is drained by Terewatoa Stream, in the Kawakawa River catchment,[2] and is part of Te Ahu Ahu wetlands.
The threatened bird species kōtātā (fernbird) and spotless crake (pūweto) live in the wetland.[3]
The Kauri Timber Company had a tramway near the lake for hauling out kauri logs to the nearby Okaihau branch railway.[4]
