While officials have long said that Iran would be able to compete in the United States, it has not been until very recently that any final concerns have been laid to rest.
Even once their participation was beyond doubt, politics have dominated the build-up to Iran's World Cup campaign.
Until this week, the host nation, the United States, had been at war with Iran.
An agreement to halt hostilities and reopen the Strait of Hormuz was only announced on Sunday.
Some members of Iran's staff have not been granted visas for the US, while they have had to train in Mexico instead of their originally planned base in Arizona.
Once the game started, though, the focus was firmly on the football as one of Asian football's heavyweights were an imposing presence from the off, with the attacking talent of Taremi a particular threat.
They played slick, well-drilled football in the final third and showed a constant sense of urgency as they took an attack-minded game to New Zealand.
It was far from one way though, with New Zealand racking up 14 shots to Iran's 17 - and neither side able to find a winner.
In fact, the All Whites had the game's most intriguing player in forward Just, whose display backed up his fine club form from 2025-26 when he scored seven and assisted eight for Motherwell in the Scottish Premiership.
His link-up with Wood caused problems throughout and his two well-taken goals were reward for a performance full of creativity.
It is the type of World Cup display that attracts potential suitors, but afterwards Just was concentrating solely on his nation's prospects.
"One goal was nice, two was not something I could ever have dreamed of," he said. "This team is really special, but we know how tough our other opponents are.
"We have a lot of work to do."
