The original design for the ensign was submitted to King George VI by the Governor-General of New Zealand, Lord Galway.
On 16 November 1938, by an exercise of the Royal prerogative, the New Zealand Civil Air Ensign was instituted. Thereafter it was "recognised as the proper national colours to be flown by British aircraft registered in New Zealand".[1]
Use
The ensign may be flown at aerodromes in New Zealand, on any New Zealand aircraft and from the principal offices of airlines which own New Zealand aircraft. Additionally, the Civil Aviation Authority of New Zealand may fly the ensign from its buildings or aircraft.
