A touch of topic but a reply to Anthill's who made mention of a previous NLK incident....
Anthill,
with regards to the Ozjet NLK incident you mention, the OJ 737 diverted from NLK and landed at the planned alternate (NOU) with statutory reserves, even with the problems the aircraft carried.
OJ always planned, and always dispatched, to NLK with fuel to go elsewhere no matter how good the TAF was, be it AKL, NOU, BNE, OOL, SYD etc, etc.
