This is not strictly seat comfort, but another ‘comfort’ aspect of Air NZ PE is that there are dedicated toilets in that section. This may be a small thing for some or a deal-breaker for others. In comparison, for example, in SQ’s otherwise great PE, the toilets (while kept clean, serviced in that impecccable SQ way) are in the economy section so that means hauling yourself out for the walk down (no big deal), but it is the queues and the waiting and then avoiding getting in the way of trolleys etc. So you have to time it, that means bobbing up and down to check the aisle etc. A pain on a long-haul flight in a window seat.
