Now The Southland Times reports (here) that a "52 year old Invercargill artist" has been arrested and charged in relation to the theft of the egg, which was very well recorded by the museum shop's video cameras. Apparently, the perpetrator was also brought up on unrelated shoplifting charges, and returned the egg (voluntarily?) after two days, leaving it in a shopping bag at the museum reception desk. This seems like a very basic and spur of the moment robery...probably done merely to pay off some minor debts, as without official collecting history paperwork and export license, no responsible dealer, gallery or auction house should touch it. Much the same as what should be done to perform due diligence on any suspect archaeological artifacts...an infrequent and incomplete process at best.
