One would "assume" EK's company brief would have made them aware of WIP at NZAA... ???.... they also had 3 hrs to read/prep up on the way over the Tasman.
I Have operated recently out of NZAA and the WIP are (from my experience) well communicated. Im surprised someone hasnt had a moan about the ground/taxiway markings at AKL...yet!
I wonder at what point on the T/O roll they decided to "throw the safety dice" and ...."go for it".... rather than stopping.....scratching their heads, blaming someone else .... then re-calculating some more appropriate T/O data and trying again.... this time a little more safely. Guess their V1 call was replaced with..... "oh sh1t"
