I've had a parcel "held for clearance" by customs for a week now. It was a $90 clothing order, so there is no reason for it to be held. I opened a case with NZ Post and gave them the invoice, which they sent to the Mail Centre to investigate, but they have not responded and NZ Post say they can't help me further unless they get a response from them.

Customs aren't interested in dealing with it as I have not received a letter to pay the gst+duty for it's release, but I am not going to receive a letter as the items were only $90 value, so that's no help.

I've never had items held for more than a day before being released, so I am not sure what to do at this point. Does anyone have any ideas? I feel like a week considering there has been no public holidays or anything to create a hold up, is an unnecessary time to hold it.
