It's not something many people would include in an emergency kit, but there are fears Christchurch's beer supply could run out.
Lion Nathan's brewery in Christchurch sustained heavy damage in the quake, reports the New Zealand Herald.
Supplies of Canterbury Draught, Guinness, Beck's and the Macs Craft range are threatened, though the company told the newspaper reserve stock could be shifted around the country to meet demand.
"At this stage we're saying that it's unlikely that we'll be doing any production or deliveries this week," sys spokesperson Judy Walters.
"I don't think people will be going thirsty."
Other brands produced by the company are manufactured elsewhere.
