I'm looking for a new laptop, and as I'm quite happy with my Xiaomi Band, Phone, and Router I thought to buy the Xiaomi Air :)

 

But it's not officially for sale in NZ. One option is to buy it via Aliexpress, like here. However, I'm a bit worried about warranty. Dreami is a well known shop, but still I'd have to send it back to China and hope for the best. 

 

What is the best way to buy this, and having a proper warranty?
