Putting aside the political and nationalistic debates about New Zealand adopting a new flag, there are some interesting business and economic aspects.
Government officials say the cost of change should not be too high, as no private individual or business would be required to use the new flag, and could go using their old flags until they have to be replaced.
The biggest costs would be for departments to replace flags, estimated at $660,000. The biggest flag wavers are the Defence Forces (600 flags) Ministry of Foreign Affairs and Trade (318 outdoor flags, 110 indoor and 453 car and table flags) and the police (200 flags).
It could cost as much as $2 million to replace flags on Defence Force uniforms, but officials say they could also keep the old flag until they wear out. The same could be done for drivers' licences, which by law display the flag.
Those who will be rubbing their hands in glee at the prospect of a change are the three flag manufacturers with the approved design: Flagz Group in Auckland, Flagmakers in Wellington and Adams Flags in Dunedin. Considering all the departments, councils, businesses and schools which like to fly the flag, there is a lot of money to be made - depending on its size and quality, a flag can cost from $180 to $459.
