New Zealand is blessed with 1,100 rivers, 4,000 lakes and 600 billion cubic metres of annual precipitation. Of this, 11 billion cubic metres of freshwater is consumed (taken out and not returned) by human activity. Although this sounds, literally, like a drop in the ocean, the fact is that most of it falls where it is not consumed and conversely most is consumed where it does not fall.
