Lets look at the (non) issues. Christchurch "use twice as much water as Aucklanders". No surprise there as Christchurch gets half as much rainfall as Auckland (600mm vs 1200mm) so at a residential level has a greater need.

But how much water is there and where does it go: As a broad benchmark the city used 50 million m3 of groundwater a year: 57% goes to residential use, 21% for commercial and industrial uses, 17% is unaccounted for, and 5% for public use. Outside of this private irrigators around the city took 36 million m3 and industries 14 million m3.

So you have a total of 100m m3 and resident use 28.5%

Average daily use is around 275,000 m3 a day. Max use over summer gets to about 400,000 m3 a day. Aquifers recharge around 780,000 m3 a day - 95% of Christchurch aquifers are fed from the Waimak

Anyone smell a revenue gathering exercise?
