Later on 26 April, A321 ZK-NNB on NZ729, the 1830 hours that was airborne at 2005 should arrive at 2216, 96 late. This aircraft had not been used all day so whether it was in for maintenance that ran over time or connecting passengers were delayed, I don't know.
On Saturday 27, NZ722, the 0840 hours MEL - AKL has been altered to depart 95 late at 1015 hours midmorning.
UPDATE: ZK-NNB spent overnight in MEL and took off at 1022 on Saturday 27, so arrival in AKL should be 90 late at 1545. That it had to be delayed suggests both flight and cabin crew typically overnight in MEL between 'the 729' and 'the 722', so when the former is delayed significantly, the latter will also be. Something to note when choosing a flight.
