On previous promotional black plane versions (as on the Airbus above) the koru logo was made smaller on the tail section to allow greater dominance of the sweeping 2-tone silver fern. It is interesting that with their latest version, Air New Zealand has returned the koru back to a more prominent scale similar to their existing teal accented fleet.
Will this steam rumors that the koru is about to be dropped in favour of the silver fern?
