Guys in Auckland, watch your water bill.  I just got mine where they are changing to a monthly bill and also a price increase and also a volumetric waste charge (removed rates fixed charge) and also add an admin fee.  I am not really against the changes, but my bill is an estimate reading where as I always get an actual reading - I am only a few km from their offices in East Tamaki.  Looking at my meter this morning I've calculated the estimate was 12 kL under the actual, which means if the next bill does not correct the estimate before applying the changes then I will be charged about $15 more than if this month's bill was correct.  Someone is potentially pocketing a lot of cash.

Even worse, the current bill suggests that our daily usage compared to the previous bill has "dropped" almost 20% which is total cr*p when you go into winter so taking longer hotter showers.

I'm tempted to wait until next month and see if they use the actual meter reading and re-estimate this reading.  Or should I/we make an official complain to someone?  I've been in NZ almost 12 years but making official objections is not the kind of thing I'm used to, so keen to hear other's thoughts.  Thanks.
