Why Should New Zealand Be Ruled Under The Maori Flag?

I believe New Zealand must be ruled under the Maori Flag. This is because Maori tribe was the native tribe of New Zealand. These were the people who first settled in New Zealand. It was afterward that the land was taken by the Britishers. It is true that they have ruled the country for a long period of time and have done a lot for this country. However, the land still belongs to the people who are natives and it is their flag that must rule the country.
