Air New Zealand IATA codes rego's

I have come across on some days looking at the Flight aware blue maps of NZAA-NZWN-NZHN etc why is the code changing from NZ501 and sometimes read NZM501 why is this happening on FLIGHTAWARE can anyone give some updated info on this. :frowning:

I see no problem with there call signs etc NZ136 NZ 5 NZ 101 NZ 501 have not come across NZM on blue maps :unamused:

I have seen a glitch it comes up as eagle nzm

Flight links please; need to see the problem to be able to diagnose it.

Not sure if directly related to what youโ€™re seeing, but ANZ/NZ is Air New Zealand, and NZM is Mount Cook Airline (part of Air NZ Link).

Need to see the link first before we can all see the problem your having. If you look at the blue maps over the entire New Zealand mapping you will see NZM flights as the flightaware member above explained this could be what your seeing instead of looking for example NZ135 NZ136 NZAA/YBBN YBBN/NZAA same flight returning
