On average New Zealanders use 160 L of water per person per day for household use, with the highest city average rate for household use at about 350 L/person/day in Porirua.

The majority of water is not used for household use. The biggest user of water is irrigation, followed by industrial use. If these are added in to the per capita figures the average water use is 82 000L/person/day.
