That's a documentary I would have been interested in seeing, personally... alas, I (currently) reside in NYC, so NO CHANCE!
(Thank God for YouTube, that I even get to hear NZ accents occasionally.)
But yeah, you have to admit, TE901 (Erebus) wasn't exactly Air NZ's finest hour, and if they are still a premier advertiser on TVNZ (uh - I'd say probably!) then 10.30 at night is probably the earliest they could get away with airing it. Sadly.
And I say that as someone who weeps with joy when stepping on to an Air NZ flight after time "overseas" (and by that I mean - anywhere that's not Australia or New Zealand!)
