Tourism New Zealand set up a roving filming unit, which travelled through 55 towns, from Catlins to Cape Reinga, to capture the reviews.
The studio was part of Tourism New Zealand's 'What do you say UK?' campaign. It allowed visitors to make a short film about their trip, which was then edited and posted on social networking sites around the web.
Tourism New Zealand said the campaign is a first in tourism marketing, enabling travellers to share their experiences through social networking.

Gregg Anderson, Tourism New Zealand's regional manager UK and Europe, said: "Social media is used by people from all walks of life to connect with people back home while they are travelling.
"Add this to the fact that word-of-mouth is one of the most effective marketing tools to promote a destination, and with 120,000 views our mobile movie studio has really proven its worth."
Tourism New Zealand is currently developing the next phase of the 'What do you say UK?' campaign to be announced later in the year.
