The term "Maoris" refers to the aboriginal people of New Zealand. Option 1, Fiji, is incorrect as the indigenous people of Fiji are called the iTaukei or Fijians. Option 3, South America, is also incorrect as the indigenous people of South America have diverse ethnicities and are not specifically referred to as Maoris. Option 4, Tasmania, is also incorrect as the aboriginal people of Tasmania are known as the Palawa or Tasmanian Aboriginal people. Therefore, the correct answer is option 2, New Zealand, as Maoris are indeed the aboriginal people of this country.
