Here's one for an "Eligibility Expert" ....
Player born in UK (2000)
Parents born in NZ : NO
Grandparents born in NZ : NO
Can player get NZ Citizenship / Passport before residing in NZ ?
If Yes ..Eligible ?
Depends. If he was eligible for a NZ passport at birth then yes, through Article 5. If not, then he's acquiring a new nationality so wouldn't meet Article 7 criteria.
