Wetlands are unique features of the New Zealand landscape. These can include lakes, ponds, lagoons, bogs, salt marshes and estuaries. Landowners with significant wetlands on their properties should consider protecting and restoring them as important natural habitats.
Wetlands slow and filter water flowing off the land. In times of flood, water is absorbed by wetlands and is slowly released again in summer. This helps maintain flow in waterways, which is good for surface water takes and in-stream life.
Smaller wet areas, such as seeps, can also play a role in filtering pollutants from runoff and groundwater.
