Maimai, is the New Zealand word for a hide for wild fowl hunting. These are on the Whangamarino wetlands, which is the second largest bog and swamp complex in the North Island of NZ, It's an outstanding site for promoting the value of wetlands and species conservation. Ironically duck shooting starts 7th May
Nice image, it is interesting that there is shooting on the wetlands, but I guess mallard ducks are introduced and do need to be controlled as do most introduced species which have found our benign climate to their liking.
