McGoo,
That used to be the case when this temporary runway was first used for operations with EGPWS, but the databases were amended long ago and this should no longer be a factor.
What seems to be getting little airplay is the "unidentified light aircraft". As I recall, during green chart operations, the Auckland Terminal area is supposed to be closed to GA operations.
Who was the "unidentified" light aircraft? I hope he gets the rocket he deserves.
