Lovely stuff Andy. Was the Yellow Eyed Penguin at Curio Bay? Spent about 7 hours over 2 days there, waiting for a 5 minute glimpse . Had a better view of them taking The Elm Wildlife tour on the Otago Peninsula, from Dunedin a couple of years back, 7 in about an hour, running the gauntlet of several juvenile NZ Sea Lions. Thoroughly recommend that trip if you get chance.
