I think some of you are misinterpreting the FIFA requirements.
Article 6 (six) doesn't apply to New Zealand, New Zealand Football are barking up the wrong tree if they think it does. Article 6 applies to FIFA members that share a nationality with another FIFA member. The Oceanian example of this is Tahiti, they share a French nationality with the FIFA member France.
The issue is why did FIFA allow him to play in the U20 World Cup in May, using the same eligibility criteria that the OFC have used to deny New Zealand the opportunity to compete at the Olympics.
FIFA do make mistakes though. For example, during East Timor's recent loss against United Arab Emirates, the team was full of Brazilians. http://www.fifa.com/worldcup/matches/round=275171/...
I personally, think it comes down to how Article 7, clause 'd' has been interpreted. It's too open to interpretation and places no restriction on players who are younger than 18 when they obtain citizenship. What it says is that if a player obtains citizenship after turning 18, he has to live on the territory for five years to become eligible for the national team.
I think it's a matter of interest to find out whether Wynne, who had arrived aged 14 and 10 months in January 2010, was a New Zealand citizen by the time he turned 18 in March 2013.
As for the Vanuatuan who knew about it? I'd look no further than Christian Kaltabang. He sits on FIFA's Player Status Committee.
Also, it would seem that New Zealand Football were able to select the U20 World Cup without it being checked for eligibility:
a) all players shall hold the nationality of its country and be subject to its jurisdiction;
b) all players shall be eligible for selection in accordance with the FIFA Statutes, the Regulations Governing the Application of the FIFA Statutes and other FIFA rules and regulations.
2. In addition to the above provision, each Participating Member Association shall ensure that all players of its representative team were born on or after 1 January 1995.
3. In addition to the above provisions, players who have already taken part in a preliminary or final competition of the FIFA U-20 World Cup and/or an Olympic Football Tournament and/or the FIFA World CupTM may compete in this competition provided they still fulfil the above age requirement.
4. The Participating Member Associations are responsible for fielding only eligible players. Failure to do so will lead to the consequences stipulated in the FIFA Disciplinary Code.
5. Protests regarding the eligibility of players shall be decided by the FIFA Disciplinary Committee in accordance with the FIFA Disciplinary Code (cf. art. 10 par. 3).
Seems like a credible source but it's a bit pants that he sat on it until we played Vanuatu. He could have informed PNG etc before but chose not too. shoddy FIFA/OFC self centred beurocrats
