The purpose of benchmarking is to determine the levels of nitrogen and phosphorus from rural land within the catchment areas of Lakes Rotorua, Rotoiti, Rotoehu. Okareka and Okaro.  These nutrient levels are called the 'Rule 11 benchmark'.  The landowner is then required to manage their land within their benchmark in order for the land use to remain as a permitted activity under Rule 11.

All properties over 0.4ha in the catchment areas must be benchmarked.

How is a property benchmarked?

A property’s allowed nutrient limit, or benchmark’ is set using information on how the land was used during the ‘benchmark’ period of 1 July 2001 to 30 June 2004.  This information is entered into OVERSEER© – a farm nutrient budgeting model.  This generates an annual average nutrient allowance of nitrogen and phosphorus.

What does the benchmark mean?

All properties in the Rule 11 area must comply with Rule 11, even if the property has not been benchmarked. 

This means that current and future owners are still restricted by the nutrient loss from the land’s use during the benchmark period.
