Here in New Zealand, we grow some of the highest-quality produce in the world.
But, if you can't get it to the consumer, what's the point in growing it?
Vegetable growing operations in years past were located close to towns and cities, so the people living there could have easy access to fresh vegetables.
The expansion of our urban centres has seen these operations being taken over by houses and moved further away from consumers. Also, as much of our produce is exported around the world, we need to have good transport links to the cities and ports, both for those exports and for domestic supply.
Gisborne, for example, is a highly productive growing area for all sorts of produce. But there is, essentially, just one road out to the Bay of Plenty, and another down to Hawke's Bay; if either (or both) of those roads close, Gisborne is isolated, and its produce cannot get out by road.
