Earrings at auckland airport in auckland airport, auckland

Hi I travelled to NZ recently - bought a pair of earrings at Auckland Airport then promptly lost them when back in Darwin. I have rung the shop in Auckland Aiport who have another set for me but they WILL NOT take payment over the phone or internet - which is very frustrating. Lovely lady at the shop has put the earrings in an envelope under the counter and is ready to give to someone to pick them up - pay for them. Once this is done, i just need them to be put in an express post envelope to my home. I will provide payment for the earrings and your fair cost to go to airport, pay for earrings, take them to post office and post to me in Australia Due date : Before Sat, 10th May Location: Auckland Airport, Auckland Thanks
