The sooner the better for NZF surely, re trying to plan friendlies against possible 'similar opposition'.
And yes of course AWs need to qualify out of OFC first.
But given most if not all of 2021's FIFA windows will be taken up now with OFC qualifiers, March 2022 will roll round very quickly, so whatever quality friendlies NZF can lock in pre then will be very important.
Though wouldn't be surprised if FIFA pushed back the intercontinental playoffs, until say June of 2022 - given Qatar WC is not until Nov/Dec 2022.
Playoffs in June would greatly held AWs prep time (could go into a proper 2 week camp together), not being sandwiched into European/A League/MLS club seasons like March playoffs would be. And no opposition side will like coming to Auckland or Wellington in June!
