This is a weird one

New Zealand Has Ordered More Than 1,200 Square Feet of Skin for Volcano Victims

"To meet the patients' needs, doctors will require 1,292 square feet of skin, the majority of which has been ordered from the United States, he said. For context, an average adult has about 11 square feet (1 square m) to 21 square feet (2 square m) of skin surface area, according to CNN."

That's 117 times the total skin area of a single patient. There were only 47 people on the small island that erupted (at least 6 dead, some missing, so at most 41 survivors to need medical treatment). The article says "additional grafts" are often needed (after the initial treatment), but is it reasonable to need 3x or more the total skin area of all the possible patients?

Is there any plausible medical reason for needing so much skin for grafts/treatment? Or is this cover for New Zealand wanting … um, a lot of human skin for something else?
