Due to a fuel shortage @ AKL Air China 789 B-1591 operating CA784 from AKL routed via Sydney on its way to Beijing to pick up fuel last night.
ABC article states it could be 10-14 days to fully restore fuel supply at AKL airport due to damaged infrastructure...

No doubt SYD will see further diversions from AKL over the coming days.
