Plenty of people throw that idea around again and again, but it isn't going to happen. FIFA doesn't care to force the issue (they have no incentive to do so and there's no evidence that they desire a merger having already backed OFC independence), the OFC doesn't want it for obvious reasons (going from guaranteed representation at every major tournament to possibly permanent irrelevance), and the AFC is not interested (they cover a third of the globe now; adding the OFC would bring them to half the globe, dramatically increasing costs of tournaments with little competitive benefit to them since OFC teams aren't even that good). Nobody gains from an OFC/AFC merger except fans who just don't like the OFC. Nobody really wants an OFC/AFC merger except those fans. We're not going to see it. "Probably be confident"? That's not much relative to what New Zealand already has, and frankly it is also optimistic (NZ wouldn't be terribly confident of their chances in the OFC at all). Let's dive into this. Say that I'm New Zealand (let's just try to put ourselves in their shoes here). I know where I stand in the football hierarchy. I'm a big fish in the small pond that is the OFC, but I'm not a big nation. I can't even say I'm consistently top 100, and though I dominate in my small pond even the minnows around me occasionally can test me in any given game. The teams in the AFC are much stronger, so I'd have much more to worry about there. Even with 9 berths, there's no reason for me to be all that confident that I'll be qualifying in the AFC. Between the Middle Eastern rivals (UAE, Saudi Arabia, Qatar, Oman, Syria, Jordan, Iraq, Bahrain - all easily at or above NZ's level), the East Asians (China, Japan, South Korea, North Korea - most above NZ's level, all at least even), the Central Asians (Uzbekistan, Kyrgyzstan - at or above NZ's level)), and Australia (much better than NZ), I could easily miss out on most cycles. The same goes for the youth World Cups. In the OFC, there are 2 berths to fight for at every U17 and U20 World Cup. I'll rarely miss out. In the AFC I'll probably be out more often than not. Same goes for the Olympics. Meanwhile, in the OFC, I'm the dominant power. I'm by far the largest federation and I win the vast majority of the time. If I don't win any OFC title, it's a huge upset. I can be extremely confident that I'll get to every WC (U17 or U20 or Seniors) and every Olympics. And if I do not make every single tournament, I can be certain I will make the VAST majority of them. In the AFC, I cannot be confident of any of that. As soon as I join the AFC, my odds of making any tournament decline dramatically. So why would I even entertain a move? Put yourself in New Zealand's shoes right now and ask that question. In your current position, you can be nearly certain of your odds of making EVERY tournament. What precisely would get you to dramatically reduce that certainty to move to the OFC? What benefits could outweigh such a huge cost? I'll answer for you: nothing and none. There are no benefits that could outweigh that cost and thus there's nothing that'd get you to move. In fact, there are very few benefits at all. NZ joining the AFC not only decreases their odds of getting to any tournament, but enhances travel costs and puts more financial strain on the federation. So not only would they be less visible on the global stage, they'd be poorer for it too (taking into account the loss of funds they would otherwise have earned from those consistent qualifications). And there are also the politics - with just 11 members, every OFC nation has a pretty decent say in how things are done. NZ, as the biggest federation, has a lot of clout. After combination with the AFC, they'd all be pretty much irrelevant. So add sovereignty and self-determination to the list of costs of a merger for the OFC. Most of what I've said about NZ goes for the rest of the OFC too, btw. If you're Fiji, Tahiti, New Caledonia, or Vanuatu you're not expecting to win over NZ, but every so often you know you can pip them for the occasional upset. You'll never get by them in World Cup qualification (you never even come close, really, NZ takes it too seriously), but things are a little closer at the Olympic and youth levels - you have a real chance of getting the occasion Olympic appearance. You may even catch NZ slacking and slip into the Confed Cup (which may go extinct soon, but still). Also, since 2015, every U17 and U20 WC will take two OFC teams, meaning one of you will get a shot even if nobody can upset New Zealand. Join the AFC and all that goes away. You may never make a major global tournament again. Sound like a good deal for them? I don't think so. They'll never go for it.
