apple return items - account doesn't have return item link

I purchased new iPad Air from Apple online store and received it recently, but there is no such " return item" in my apple account. I'm in New Zealand and placed the order from New Zealand Apple online store. The return policy says to process return apple products just log in apple account, and click the "return item" link. The problem is that there is no "return item" link in my account. I looked everywhere.

can anyone help? please
