It doesn’t have anything to do with food prices. It shows how much of your income is spent on food. In poorer countries (south america, asia etc) they earn less so spend more of a percentage of their income on the food they eat. NZers have more disposable income so spend less money on food as a percentage of their income.
It has nothing to do with food prices at all but rather about the % of income spent on food. I guess low income countries spend more as % of total income but don’t worry we are well on the way to raising our number – what with wages down, prices up, inflation at a 21 year high etc etc.
I would actually say this map shows exactly the opposite. Compared to countries of a more similar diet, and a relatively moderate policy on allowing the importation of food products we are pay the most (US / Aus / Uk). Compounded by the fact we produce most of our own food (meaning transportation costs are not the answer) we see that we pay quite a large percentage on food.
Which isn’t surprising considering milk in the UK is cheaper than in New Zealand, who happens to provide a huge portion of the milk powder over here.
The comparison with Europe can be explained by their massive trade barriers and also the way they buy food (from small producers) and a higher emphasis on fresh food rather than heavily processed foods which are stupidly cheap in places like the US and UK.
With a duopoly supermarket system and many monopolies on production in NZ, it really isn’t a surprise.
