Yes the biggest issue is as Aircrew we are supposed to hypothetically calculate water depth with rain rates etc, yet Auckland tower was unable to give a condition report on the runway. Hearsay says it was about 50mm depth at the time of the AirNZ landing. There is a disconnect between Flight Ops and everyone else on this. The best guesstimate was a safety car dude said the water depth was half way up his boot. Ridiculous.
