Harry travelled by boat to uninhabited Ulva Island during the second day of a weeklong visit to the South Pacific nation. He was immediately greeted by a weka, a flightless bird which looks a little like a kiwi, minus the long beak.
Conservation workers on Ulva have eradicated rats, stoats and other predators that can eat the eggs of native birds, allowing the birds to flourish.
Harry first travelled south to Stewart Island, population 378. About half the residents turned out to greet him at a community hall or wave to him from outside. He delighted them by shucking an oyster, a local delicacy.
While that didn't happen, Harry nevertheless appeared impressed by the unusual plants and birds he did see.
Harry is also scheduled to visit Christchurch, Whanganui, Linton and Auckland.
The prince is the grandson of Britain's monarch, Queen Elizabeth II, and fifth in line to the throne. He arrived in New Zealand from Australia after a month-long embedment with the Australian army.
