Mustafa,
One can also taxy along "bravo" to proceed to the 23L threshold. However, this is not a regular occurence for "heavys" from the international terminal and perhaps causes more confusion than is intended.
Whether the alleged incident occurred or not, you may be interested to know that QF has recently issued an Intam alerting crews to "somewhat confusing" taxiways and apron areas at NZAA !!
