Planning on moving back to Auckland for a while. Would like to bring my Ryzen system over. GPU cost was $699 and other components are $810 when bought eight months ago. My plan is to carry each component in it's box on carry on luggage. Hoping not to pay customs duties under the personal effects? But would just like to check. Have emailed Customs NZ and would like more info before I ring them + anyone's experience with this.
