National Performance Review


The National Performance Review provides a benchmarking tool for local authorities and other organisations providing public drinking water, wastewater and stormwater services. Water New Zealand has undertaken this review since 2007 and it provides annual and trending information since then. Correspondence regarding the review can be directed to technical@waternz.org.nz

International benchmarks

Data from the review is included in the The International Benchmarking Network for Water and Sanitation Utilities (IBNET) database. This enables international comparisons of some performance indicators which can be accessed here.

Indicators in the national performance review do not always match IBNET indicators exactly. An FAQ sheet outlining the assumptions that have been used to map National Performance Review Indicators with IBNET can be accessed here.

Wastewater Treatment Plant Inventory

The National Performance Review is used to provide New Zealand’s only collated source of data on wastewater treatment plants. Geo-spatial and raw data for 252 Waste-water Treatment Plants (WWTPs) contained in the inventory can be accessed here.
