Taiwan's national television channel 8 TTV is highlighting Milford Sound as part of its focus on New Zealand as a world leader in conservation and sustainability.
Journalist and presenter Zoe Yih-Zu Lin and her crew, which includes two cameramen and a presenter-researcher, joined Real Journeys for a Milford Sound overnight cruise last month.
Ms Lin said the prime-time current affairs programme Hotline, was making a special series on countries with qualities it admired.
"Taiwan is a small country with a huge population. We are looking at what we need to do to improve over the next 100 years," she said.
Ms Lin said her crew had travelled to Austria to look at its music and education; Singapore for its competitiveness and economic performance; Japan for its subcultures; China for its water policy; and France for food and fashion.
They chose to showcase New Zealand because of its reputation in conservation and sustainability.
"New Zealand is six times the size of Taiwan and there are only four million people. We have 23 million people, so we're six times your population. Because land is small in Taiwan and the population's big, people are trying to survive first, sustainability is last.
"I can see the priority of the New Zealand population is for sustainability to be on top. The challenge for Taiwan is to think about the next generation. It's the most important thing," Ms Lin said.
The crew filmed Real Journeys' recycling efforts - all waste is taken from vessels and, where possible, recycled or sent to a pig farm.
They also wanted to know about the company's fuel efficiency initiatives and were impressed with the care taken by the vessels' crews not to disturb wildlife.
