Geninue question - New Zealand lamb is the same cost as British lamb on the supermarket shelves. Yet the New Zealand farmers have had to ship their lamb half way around the world and still clearly make a profit. So what are British lamb farmers doing that so increases their costs that New Zealand farmers don't do ?
Have you tried speaking to a sheep farmer? I don't know enough about the New Zealand economy but potentially their costs are lower than those of a British farmer?
