The 54-year-old could have done well with the current All Whites' generation, but it was always a long shot, as Arnold will also have his sights on the Socceroos job after the 2018 World Cup.
So Arnold is off the list — but who is on it?
That's shrouded in secrecy, which is standard in these situations, but no one without all their professional coaching badges will be considered.
NZF CEO Andy Martin has confirmed it is a prerequisite, and Technical Director Andreas Heraf shares the same view.
"It shows a certain quality," Heraf told the Herald. "It means you have done good stuff before just to get the allowance to go there and it is not that easy to pass. And it is our right, and our clear pathway, and that is what I wanted to have."
It's a puzzling stance. Such qualifications should be seen as a 'cherry-on-top' scenario, but surely not a primary factor.
Firstly, here's a short list of coaches, who managed, in both senses of the word, without the Pro Licence.
Terry Venables, Sir Bobby Robson, Bob Paisley, Brian Clough and Sir Alex Ferguson. Not a bad list.
There's nothing wrong with the qualification — and by all reports it is an extensive, varied course — but it should be viewed in context.
There's a limit to what can be learnt in a classroom. Look at this sample from the 2014 course run by the English FA.
There were two sessions with Sir Clive Woodward on developing a winning culture, an Q & A with Carlo Ancelotti and a talk from then Warrington Wolves Super League coach Tony Smith.
It's all worthy stuff, but being a successful football coach is all about time on the training pitch, time with the players, and most importantly time in the dugout.
There are so many soft skills that are required, and after a while it usually becomes quite clear, simply by results and the player development under your watch; either you can, or you can't.
Secondly, such a mandate virtually rules out any local contenders. The Pro Licence isn't offered in New Zealand, and won't be anytime soon, as Fifa see Oceania as an amateur confederation because there are no professional leagues in this region.
It makes it difficult to obtain the badge if you are based in this country, as there would be an investment of thousands required for regular flights across the Tasman, and there is limited flexibility around missing even a single session if you want to pass the course.
There's nothing wrong with hoping that local coaches will work towards such qualifications, but it shouldn't be a central tenet to a selection process.
