This is a slightly different fern design to Aotearoa 2 which I did not realise was the fern design of the Rugby Union. They may be very happy to allow their design to be used. If not then there are many designs available. The flag is three bands for the three islands, contains the Maori colours and the silver/white fern design. It is very distinctive from a distance and will be clear in light winds. It should maintain its colours. It will be instantly recognisable and easy to draw or produce.
