Today I went to drop off OH at Auckland international airport and came across a bunch of documents with passport & Singapore Airlines arrival card left in the trolley, I'm not sure if the person who missed it is part of this forum but if that's the case then please go to Auckland Airport (International terminal) Help desk - for a hint, the part of the name on passport was "Sohan Singh" & I think someone (with hair turban) in Maroon Van picked him up.
Cheers !
