A Dunedin tech company has come up with a high tech proof-of-origin mark that can distinguish New Zealand made wines.

It's a little more advanced than a standard 'made in New Zealand' label on a bottle, as it uses advance science to determine whether or not the wine was actually made in New Zealand.

Tech company Oritain partnered with Pyramid Valley wines to bring forth this latest form of CSI for supply chain technology.

Their Head of Strategic Sales, Sam Lind, joined us to talk us through this launch.
