Mikeaat has added New Zealand to flightsim.to. However, being a first draft, I did spot a couple errors, gaps in the elevation data that caused huge flat terrain areas that cut through mountains north of Kaikōura Peninsula. Other than that, it’s really gorgeous.
Also, the files are huge compared to the Orbx solution. But it may be weeks before it enters Marketplace, if your holding out for that, like me.
