A 15% GST is applied to any shipments imported into New Zealand. GST is calculated based on the total cost of a shipment, which includes the value of what you ship, the cost of shipping, and any additional charges (e.g., insurance).

For example, if you purchase a guitar from the US for 600.00 USD and shipping costs 50.00 USD, you would pay 15% GST on the total cost of the guitar plus shipping (97.50 USD}. Your total cost to purchase and ship the guitar would be 600.00 + 50.00 + 97.50 = 747.50 USD.

While MyUS collects GST on total shipment costs to New Zealand, other government fees may apply to your shipments, which can incur additional GST. Those fees/GST are not collected by MyUS, but you would be responsible for paying them when your shipment arrives in New Zealand.
