Upon relieving payment, your product will be shipped promptly. The majority of products exist in China. I have sent many products back to NZ and have found that it takes an average of 11 days to reach the door. That being said, some items have taken 3 weeks.
If the product is in NZ, I will notify you and return part of the delivery fee. At this moment of typing, I don't have an automatic way of doing this.
