Wetlands were defined in the RAMSAR Convention on Wetlands signed in Ramsar (Iran) in 1971 as areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres.
New Zealand wetlands tend to be places of poor drainage or where water accumulates, sites where seepages or flooding is frequent and interfaces between land and streams, rivers, lakes and estuaries.
