I think we might have a similar situation. We are on NZ91 from AKL to HND on March 24, 2019.
I did have C seats reserved on the 787. Now I am unable to (re)select them or open the seatmap on airnewzealand.co.nz. It still says that it's going to be a 787, but at least on Expertflyer and on CheckMyTrip the seatmap shows the 777-200 configuration.
Also the flight times have been slightly adjusted (only a couple of minutes).
Would you think that this means a change from 787 to a 772?
Thanks!
