On our way back home to Auckland with Air New Zealand on 29 December, there was a very substantial business jet parked on the control tower side of the airport. Given its dark blue and white colours and the fact that it was a long way away from the terminal and having to shoot through glass it was challenging to get a good photo. Here are a couple I managed:
Boeing 737 MAX 8 BBJ N3E was reported to have bought the co-founder of Snapchat, Evan Spiegel to the capital. The registration is just behind and above the last window (if you could see it!)
And here are the contrasting winglet shapes from Boeing and Airbus.
