"It is a reminder to handle items with care but also a duty on the retailer to take care with their goods and ensure people are cautious with valuable items," Hammon said.
If the customer was careless, they would be liable to cover the cost of damage, Retail New Zealand's general manager of public affairs Greg Harford confirmed.
"If the customer was handling the item roughly, they will be held responsible for the breakage."
The same applied for retailers, Harford said.
"If the retailer had displayed negligence, for example if they had stacked the item poorly, they may be responsible."
First Retail New Zealand's managing director Chris Wilkinson said it would be "commercial suicide" for a company not to be insured for an item of that value.
"Businesses should be insured for breakages within stores, if they weren't there would have to be an agreement before entering the shop.
"Goods of high value should be locked behind a glass cabinet. It would be unreasonable to make items of that value available to the public."
