Percival certainly grew up here.
Did some digging. Born in the UK. Came to NZ as 14 yr old in 2003, and then left for the US in 2008 at age 19 yr. So yeah had a 5 year stretch in NZ - some of her growing up you could say.
Riley has a natural right to NZ citizenship as a child born of a New Zealand parent.
Wynne was an immigrant, neither born of New Zealander parents nor in New Zealand, so was required meet FIFA criteria of residency.
The question was about comparing the situation of Ria Percival to Deklan Wynne (which on face value appear pretty similar). Not Riley.
