Another two stores are listing the product in NZ now; PBTech is selling it for $205.85 NZD incl. GST ($210 - $218 after shipping), and Techworld is selling it for $211 NZD but is out of stock. Both PBtech and Ascent claim to have it in stock, but my order from the latter isn't meant to ship for a few weeks still. PBTech claims it will dispatch it in 1 working day, but I wonder if they actually would if you placed an order.
Gigabyte did an official press release recently and the board has been appearing on various news / tech sites in the last week. Can't be far off now.
