By the way, I must mention top-rate service the other way round, in the post office in Titirangi. We finished up our visit last year with more things to bring home than would go within our baggage weight allowance, and the Air NZ charge for excess was HUGE. Thank goodness we'd packed our bags with time to spare and the scales to hand. We did a sort of jigsaw puzzle of getting the heaviest things in the luggage while leaving out the least urgent/lightest things, then weighed them and went for advice on how best to send them, which was kindly given, with lots of consulting of manuals etc. Then the man also suggested a better way of describing the contents. Brilliant.
