A bunch of new offerings that won't be available for at least 2 years.
Air NZ is excellent at marketing spin and this release is no different. By the time some of this stuff is released it'll either be standard or outdated.
Kiwi_flyer Apologies I'm responding to each line of your post but since you've posted each new product I can't help myself.
Skynest - book up to 4 hours in a sleep pod.
Given it's taking up at least 2 rows of economy, you'd expect a 3-4 hour session to cost around $400-600. It'll be interesting to see if people bite on this offer. It takes me a while to get to sleep and I can't imagine be woken and kicked out would make too many people very happy.
Economy stretch - rebranded exit row.
Clearly the idea of Economy+, Economy X or Space seating hasn't made it's way to Air NZ yet... oh wait clearly Air NZ themselves has forgotten the Space+ seating they had on long haul flights years ago but I guess this time status holders won't get free access and instead it'll be $$$ that gets you an assigned seat here.
Economy - wider screen, new seatback pocket.
Cool.
Economy plus - hard shell so recline by sliding seat bottom forward. No more invading space of pax behind you.
Having flown this type of seating in both economy (Cathay Pacific) and premium economy (old Air NZ 777 seats + Air France premium economy), I can't say I'm a fan and many reviews of the above mentioned also agree that reclining you seat and losing legroom isn't ideal.
Sky pantry - self service snacks and drinks.
This is something that airlines like Qantas have had for years on their A380 and hardly "revolutionary".
Business Premiere - reduced angle seat with privacy screen.
Business Luxe - small suite with door.
So the two business products look fine for a product in use right now, but I suspect just like the current seat they'll be very quickly dated. Earlier this year I flew ANA's the room business class and if you gave me a choice between the new Air NZ J seat or what ANA has on their 777's then ANA would win hand's down. The business class seats look no more special that what most carriers have as their current J products but the huge difference is they're typically not using them for 17 hour flights.
