Walking on uninhabited islands at 4am and coming face-to-face with boisterous sea lions are part of daily life on the subantarctic Auckland Islands, a Hamilton science teacher has discovered.
Jeremy Tizard spent two weeks in the Auckland Islands in November, helping with a Department of Conservation yellow-eyed penguin monitoring project.
The Auckland Islands are New Zealand's largest group of subantarctic islands, situated about 460km south of Fiordland.
His first encounter with some of the local wildlife came when he helped unload gear for some passengers who were staying on the islands.
"Straight away these things are in your face, they're coming right up to you - like a young teenager with attitude that wants to have a tussle, sort of thing.
"You're not supposed to look at them because that's like a challenge. But it's quite a big animal coming pretty close."
"For me it filled up the tank again and again and again, and just with inspiration and education and all the rest," he said.
The trip started with a thorough quarantine check in Invercargill where boots were sterilised and "everybody's gear got checked for any seeds in your socks or anything like that".
The group then took the yacht Evohe to the islands, a 31-hour trip.
Tizard spent much of his time at the islands watching for yellow-eyed penguins, which he described as cute but cautious.
"They're just cute. They're hilarious little things... You might watch [the penguins] for hours just standing on the edge or working their way down a rock shelf. They might look for half an hour or they might look for a lot longer," he said.
Yellow-eyed penguins are among the rarest penguins in the world and can grow up to 65cm, he said, and he got within a metre of one of the birds on watch.
"You go on a wonderful adventure, hopping in a zodiac [boat] to head out to start your morning count on whatever island, or sometimes counting from the boat. Strong winds and you could see snow sprinkled on the hilltops around you at times."
Tizard's biggest penguin count in a single session was 11 birds, on Enderby Island.
Counts there tended to be higher because cats, pigs and mice had been eradicated, unlike on Auckland Island, Tizard said.
Some days he might see just three penguins between 5.30am and 9am - after which he would head back to the Evohe for a hot chocolate.
Seeing four types of albatross up close fascinated Tizard, as he remembered seeing one in a museum as a child.
On the islands he got close enough to see the feather patterns of a royal albatross through binoculars and witnessed the courtship of the light-mantled sooty albatross, which was "like stunt gliding".
Tizard also picked up knowledge from two geologists on the trip, and hopes to share his experiences with students in 2016.
