The $25 million spent on planning a new flag is only the beginning - hundreds of thousands more will be needed if a new ensign is adopted.
Figures compiled by the Ministry of Justice reveal Government departments alone will have to spend more than $660,000 to get new flags. The New Zealand Defence Force has the most flags. Its 600 standard outdoor flags will cost $459 each to replace.
The Ministry of Foreign Affairs has 318 and the Police have 157 flying at stations around the country.
The cost to replace Government department stocks of 1,278 outdoor ones, 249 indoor ones, 11 ceremonial flags and 547 that flap around on car pennants and tables is estimated at $663,612.
The figure does not take into account the 2600 schools that would need to replace the national flag.
