The Kopuatai Peat Dome is a wetland on the Hauraki Plains in New Zealand.
The 10,201 ha wetland was listed under the Ramsar Convention in 1989 as a Wetland of International Importance. It is one of only three rare New Zealand examples of a restiad wetland, those containing the botanical Family Restionaceae.
It survived extensive draining of the wetlands on the Hauraki Plains and was given protection in 1987 when it came under the administration of the newly formed Department of Conservation.
