When flying in to NZ airport, doesn't the MAF charge only applies if bringing in food or wood products that have to be tested?
When I flew in last year, AirNZ was very kind to me. I brought over a central vacuum unit as my 2nd check in and expected to pay a 2nd baggage surcharge or at the minimum, the oversize baggage fee. However, checking in at YVR airport (flying to AKL) counter, the worker made no mention of a fee. She just directed me to take the rather large box to the oversize counter and that was it. Checked in all the way through to Christchurch.
Upon arrival, I went through customs and paid the GST. The officer said good time to bring goods in as GST was still 12.5%.
