ISDs to deliver consistently good service without looking down their noses at pax. I have had this happen twice when flying F.
When a NZ flight leaves an hour or so late, do not lie to the pax that the pilot will make up time enroute and the connection will not be a problem, then to have the FAs/ISD not give a sh!t about your connection and make zero effort to contact UA/AC from the air, then to have NZ grounf personnel in LAX tell you that the connection is no problem when it is a problem. The underlying issue here, is that all the NZ staff involved, from ckin to AKL KC, inflight staff, LAX ground staff, could not give a sh!t and just want to move you and your potential workload right along.
NZ excell at many things, I will happily fly them again, but their needs to be an attitude adjustment/wake up call given to some staff members so they deliver exceptional service, particularly to the premium pax. To not contact UA/AC from the air to check connections or make alternate arrangements is poor.
