Have flown this route on NZ 176 several times , using Business , Premium Economy and now Economy to establish the most cost effective alternative of the 6 hour ''Dreamliner" journey . My most recent was in Economy , and was a trip rendered positively hideous by the near incessant high volume. screaming of a child in the row behind me . Not Air NZ's fault , but a hazard thai is considerably diminished by travelling Business , or even Premium Economy ( both of which I have tried and quite enjoyed .
Ordinary Economy gives adequate legroom for my 185 cm , and adequate seat back recline . The single meal provided ( dinner ) was tasty and attractively presented . I was however disappointed by the fact that nothing whatsoever was offered for breakfast - not so much as a solitary cookie or plastic cup of coffee .
On balance I consider Premium Economy the best option . The full recline of Business seating is great , but the trip is too short to allow full enjoyment of this seating plus the meals, even if access to the recently opened ( and excellent ) Air NZ Perth Lounge is taken into account.
So I consider Premium Economy the best alternative , with slightly better legroom and seat back recline ..... PLUS the considerably reduced risk of travelling alongside an unsleeping and high decibel infant .
