A fast-charging New Zealand tourism business which has succeeded in breaking into South Korea says taking it slow is key in the market of more than 51 million people.

Skyline is building its second luge in the country after its first was opened in 2017.

Chief executive Geoff McDonald said the company first started talking with authorities in the luge location, Tongyeong, seven years earlier.

He told Kate Hawkesby that being "delightfully naive" helped them a lot with their success in order to overcome the language and cultural barriers.

McDonald says there was an "incredible response" to the first luge, so they just had to go ahead with a second.
