As a pilot who operated in and out of Auckland daily for the last 3 years or so, I quite agree with 3Bars assesment of the place. For the regular operators, generally no problems, but I think there are any number of traps for those pilots who might only operate there a few times a year.
As for "the SID's and STARs are insane" comment, I really cannot figure that one out, maybe you'd care to be more specific?
