These must be among the most venerable pieces of Auckland's public street art -- the Matahorua and Tainui Anchors off Wellesley Street west, beside the Bledisloe Building by sculptor Russell Stuart Cedric Clark (1959). A friend mentioned the other day that she remembered when they were first installed, way back then. No wonder, to me (all of nearly 48) they've always been right there, passed by on the way to appointments at the Bledisloe Building beyond, the Post Office, or across to the Council's Civic Building.
These are, though, just "sculptural representations" of the two anchors concerned. According to the Journal of the Polynesian Society (go to this link for photos), the actual anchors identified look quite different.
