• 1

  New Zealand publishes water bill figures in New Zealand Dollar, revised periodically — enter the rate currently in force for your case in New Zealand rather than an older stored figure so the result matches the official calculation.

• 2

  Currency is part of the math: this New Zealand water bill computes in New Zealand Dollar, so convert a foreign source figure first — applying a local rate to a foreign amount silently inflates or deflates the result.

• 3

  Keep the water bill amount and rate for New Zealand on one period and one basis — monthly New Zealand Dollar figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• Rates in New Zealand move — annually, or with each fiscal announcement — and a Water Bill result computed from last year's figure misleads budgets and quotes alike. Re-enter the current rate whenever the underlying number changes.

• Quoted rates are rarely effective rates: New Zealand providers may advertise a nominal figure while fees raise the true cost in New Zealand Dollar. Compare on one basis — effective rate, same period — before trusting the Water Bill output.
