2:10  New Zealand in the 1940's - Rick Helin

Historical footage showing New Zealand in the 1940's has turned up in California, and the search is on to find out who filmed the images. The silent footage was apparently taken by an American couple on holiday and it covers their journey from Auckland to Rotorua, Napier, Wellington, and then Christchurch and the South Island. The films were discovered by a group called the California Pioneers of Santa Clara County. Historian Rick Helin works with the group.

It's an atlas of epic proportions. In fact, it's one of the largest in the world and Wellington now has its own copy. The Earth Platinum Atlas measures 1.8 metres by 1.4m, weighs 150 kilograms and it will now call the Alexander Turnbull Library home. Not many have been made and the man looking after the book is library cartography curator, Mark Bagnall.

Ruth Beran goes to his home in Palmerston North to see one of the few water treadmills for humans in New Zealand, and watches as an athlete is tested.
