Lenticular cloud is common when the wind is right over Central Otago, and we get a few on the coast as well. And they can occur around the country. Some of them look a bit like one might imagine to be a flying saucer.
They form when westerlies blow over the mountains.
This one is sort of typical (they vary a lot).
But this stack of venticular cloud photographed by an airline pilot is way out of the ordinary.
But this from last year is also pretty cool:
