To make this long photograph, still shots were taken out the train window every few seconds for the whole 12 hr journey. Then we combined all 31,509 images into the longest snapshot ever.In magazines, the train journey ran across every single page. Consecutive street posters took up a whole city block near the airport. We took the train journey inside the terminal, running it right around the airport luggage carousels. And when people got on the plane, there it was along the overhead lockers.

Thousands of potential passengers were shown exactly what they were missing – the 681km of New Zealand you can only see by train.
