Historical footage showing New Zealand in the 1940s 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, and joins Simon Mercep to talk about the discovery.
