Who is more likely to get their gear off in the bad weather?
Today's South Island snowfall has uncovered a strange phenomenon.
Stuff called for reader pictures of the winter wonderland. We always do. But this time, for some unexplained reason, it has led to a flurry of pictures of Mainlanders frolicking in the snow in their underwear.
The photos have ranged from men striking poses to girls covering up with artistically-placed frying pans.
But why? Has the polar blast frozen some of their inhibitions? Are those in the South simply more comfortable in their own skin?
And why just the South? The lower North Island was hit hard by a rare snow dump last year yet Stuff's typical call for reader pictures didn't generate anything like this near-nude response.
Is it something in the water down there? Are the Southern Men and Women just made of tougher stuff?
