Austroderia is a species of tall grass native to New Zealand. It is more commonly known as Toetoe, pronounced and often misspelled as toitoi. As you can see from this photograph it is closely related to the South American species Pampas Grass. Sadly, Pampas has been introduced in New Zealand and often takes over the native toetoe. This photograph was taken at Stonehenge Aotearoa just a couple of hours drive north of Wellington.
