Blue Duck: The Manganui-o-te-Ao River along the road to Ruatiti is probably the easiest place in New Zealand to see the endemic Blue Duck. Unfortunately, the 2 pairs that I saw were both sitting directly under bridges. As soon as I approached the bridge they took fright before I spotted them and swam at high speed down the rapids, giving me only a couple of seconds to fire off a photo as they retreated downriver.
