Backorder for both the 256GB and 512GB Steam Decks are on Mighty Ape and arrive on the 16th December.
64GB $1199 https://www.mightyape.co.nz/product/valve-steam-deck-64gb/36…
[OUT OF STOCK] - 512GB ($1599 NZD) https://www.mightyape.co.nz/product/valve-steam-deck-512gb/3…
Also includes a free Gorilla Gaming NZ/AU USB C plug with 3M USB C cable so you won't need a international power adapter with both models.
The 64GB isn't available for purchase here, but it may be worth looking at importing one directly from Valve, as upgrading them with a 2230 SSD is fairly easy to do with plenty of tutorials available online.
PSA: However be very selective with which model you pick as according Valve, picking the incorrect model of 2230 M.2 can result in more power consumption which can cause overheating, reduced battery life, WiFi and Bluetooth Inference. Thus shorting the life of your Steam deck. A single sided 2230 SSD is recommended as some can have double sided NAND packages. So please, do this at your own risk. According to guys on reddit it doesn't seem to make much of a difference so your mileage may vary -

A decent deal considering trying import it directly from Valve is expensive with Youshop as it's about $1000 NZD ($649 USD) for the 512GB Deck + $330 NZD GST/Youshop Freight + goods clearance fees (around $174).
Since the 256GB is under $1000 NZD when importing from overseas however, it may be worth importing as it is $825 for the 256GB ($529 USD) + $225.68 NZD GST/Youshop Freight (no extra fees).
You can import it directly from Valve supposedly by making US Steam account via a VPN, then using your NZ account to gift enough Steam credit to the US account (Estimated around 64GB - $620, 256GB - $825, 512GB - $1000) , then sending to the Youshop address, pay the fees and they send it to you.
Both are expensive systems but I have been waiting to buy one and didn't really want to go through hoops to get one from overseas or pay exorbitant amounts on Trademe as a few people are selling them there. It's also nice to have a local place where you can return with a warranty without having to pay a lot to return overseas. Yes it is very expensive but it serves different purpose from a gaming laptop as you can't hold one of those directly your hands with a inbuilt controller and play on public transport without it being too bulky (even though it is very bulky lol).
Some other places you can get it are eBay, Expansys, Trademe, Aliexpress but I believe somewhere local is better in case you had to send back for any reason.
Expansys seems to have it much cheaper inc GST however I would imagine you would have to pay goods clearance fees since most of them are over $1000 NZD.
