Stitchbird (Hihi in Maori)

Here's another article: In (local) autumn 2007, 59 adult birds from the Tiritiri Matangi population were released in Cascade Kauri Park, in the Waitakere Ranges near Auckland [11][13] and by the end of the year the first chicks had fledged there.

You have seen a rare bird! Congratulations! Read this article from wiki: The Stitchbird or Hihi (Notiomystis cincta) is a rare honeyeater-like bird endemic to the North Island and adjacent offshore islands of New Zealand. It became extirpated everywhere except Little Barrier Island but has been reintroduced to three other island sanctuaries and two locations on the North Island mainland. Its evolutionary relationships have long puzzled ornithologists, but it is now classed as the only member of its own family, the Notiomystidae.
