Based on the extensive chroming, Columbus tubeset and La Redoute decal on the top tube, it would appear to be a Team Champion, which was claimed to be a exact replica of the bicycles used by the La Redoute pro team. The only years that show cables routed below the top tube are 1983 and 1984 but the 1984 model was inexternally brazed, so that leaves 1983. However, I notice that you are in new Zealand and I don't know how much market to market variation existed. However, if it truly is a Team Replica, I wouldn't think that there wouldn't be any such variation. Regardless, it's not a perfect match. This model typically came with a number peg and the blue seems too bright. The catalogues describe it as Night Blue.
