Ever since Laurel Hubbard qualified for New Zealand to represent the nation, it has sparked a debate.
The New Zealand Olympic Committee, they say she is a really important role model, that she opens up a conversation around inclusivity.
Some of her fellow competitors have been supportive of the move, of having her competing here.
