Empire Day (24 May), was celebrated widely in New Zealand from 1903 and was a major event in the Vice-regal calendar.
The Message of the Flag
Our Union Jack, on Empire Day Floats proudly in the breeze; Not here alone, but far away In lands across the seas. Wherever British children dwell Or British folk may be, On Empire Day our flag shall tell That we are Britons free... 'Tis thus it speaks, our Union Jack Its message from the mast To follow in the noble track Of heroes in the past
