My daughter in law's mother passed away and she would like to bring some of her mother's things from the US to NZ but it would require a container. My son is a dual citizen, his wife has NZ PR. I know that when they made the initial move to NZ there was no duty to be paid on used personal household goods. Does anyone know if duty is charged for importing inherited used personal household goods or is the duty-free importing only when you are arriving in NZ? Thanks.
