Hudson's selection of five wing backs reflects the physical demands on those players in his system, as they cover more territory than any other positions.
With three matches across nine days they'll need reinforcements below the first choice options of Storm Roux and Deklan Wynne.
What is the biggest surprise?
Alex Rufer.
Given the depth across New Zealand football at the moment - with more professionals than ever before and a large contingent of overseas-based players - it's a surprise to see a player who has barely figured for his club this season (no starts, 48 minutes in total) make the cut.
It reminds of a club-less Jeremy Christie being selected to face Mexico in the intercontinental playoffs in 2013, though at least Christie has some international pedigree behind him at that stage, including game time at the 2010 World Cup.
There's no doubt that Rufer could develop into a international player, but he has shown little evidence this season and it is difficult to argue he has been picked on form.
Who are the unluckiest players?
Given his performances for Portland Timbers in Major League Soccer, Jake Gleeson could count himself unlucky to not be classed as one of the top three goalkeepers in the country.
Youngsters like Henry Cameron and Liam Graham had their chances affected by untimely injuries, while Jai Ingham has a promising future ahead of him.
Jeremy Brockie may also have had a case, after a productive season in South Africa, but he has never proven himself as a goalscorer at international level, while Tyler Boyd has impressed in the second tier of Portuguese football (33 games, eight goals, five assists) but seems to be 'out of sight, out of mind.
