Auckland Water Restrictions and House Washing

Here’s a guide to help in supporting your local Auckland house washing businesses while there are restrictions on water.

NZTS provides our own water supply from sustainable sources not attached to the town supply. In doing so, we can legally operate during restrictions. Please see the graph below to see which services are best while we can only bring limited supply of water.

Soft chem house washing and proper application of moss and mould treatment to surfaces around the house provide the most efficient use of water for washing around your home. 

This graph shows the responsible cleaning methods highlighted in green and the subsequent water use
