Stuart, the guy in the video is Joram van Essen. If the name doesn't ring a bell, he's a very long-standing and rather illustrious member of the international jousting community, won the Queen's Jubilee Horn once and the Sword of Honour with the Burgundian team a few times.
As to his armour, it was my belief that he had made his armour himself while living in New Zealand until year before last. I might very well be mistaken though, and a post on Facebook suggests that his armour was made by somebody in New Zealand called Paul Barbedes. Who that is, I have no idea.
Sorry I can't be of more help
