This report covers the third year when the microbiological and chemical quality of drinking-water was assessed using the Drinking-Water Standards for New Zealand: 2000 (DWSNZ:2000).

The report differs from previous reviews in that it summarises the information generated by the survey and is divided into four sections as follows:

a general overview of the quality of drinking-water of all supplies within New Zealand;
a summary of the nation's drinking-water quality, with supplies separated into Local Authority (LA) operated supplied and 'other" operated supplies;
an overview of drinking water quality in each District Health Board (DHB) area;
a summary of the quality of drinking-water in each LA area; and
an appendix that shows microbiological and chemical compliance or non-compliance with the DWSNZ at the level of individual supplies in the LA area.
