And the winner is:

#Niue International Airport, #ICAO code: NIUE.

Found using the list from https://datahub.io/core/airport-codes and this Perl code:

#!/usr/bin/env perl -an -F,

use strict;

my $icao = $F[0];

next unless $icao =~ m/[A-Z][A-Z][A-Z][A-Z]/;

foreach my $name(split(/ /,$F[2].' '.$F[7])) {
if (uc($icao) eq uc($name)) {
print $icao, ' ', $F[2], ' ', $F[7], "\n";
}
}

Ignoring two matches with bogus data: BOBS and SWYX.

IATA check left as an exercise to readers.
