The flag features a black field, as the famous representative colour of the country, with the iconic silver fern. The fern is offset to the hoist for increased visibility and symbolic importance. Under the fern is a white hoop that runs the width of the flag. This is a reference the name Aotearoa – the 'land of the long white cloud' name.
Overall I believe this proposal incorporates a number of symbolic elements in a simple design, with a unique construction (akin to the Canadian pale or South African pall) that would be bold and iconic.
