A variant of a prior submission the concept is in 2 parts. (1) an element of continuity in the red & white stars on blue. (2) an indication of our history by combining an element the union flag in a mix of our national and maori colours of red (or ochre), white & black and UK red white & blue.
The extension of the flag/koru also represents Aotearoa. I considered adding green but another objective is to use our national colours without looking like a middle eastern/islamic country and green might go against that objective.
