Conclusions from Land Use Technical Advisory Group meeting
Goals established at the latest land use Technical Advisory Group were: independent, best-science
understanding of land use change and management options, to offer information to landowners
(including a communications plan), and independent cost : benefit analyses and reviews of:
• Land-use related environment monitoring.
• Fertiliser products.
• Feedpads and alternative stock feeding systems.
• Research on Rotorua soils.
• Up-and-coming technologies.

Nitrogen and phosphorus reduction targets
Initial estimates: nitrogen reduction target = 250 tonnes, phosphorus reduction target = 35 tonnes.
Small amounts (especially phosphorus) can be removed by in-lake and catchment works, however
some nutrient reduction (especially nitrogen) will be needed from land use activities in the Rotorua
catchment. How should this be achieved?
Lake Rotoitis nutrient reduction targets may be met if the proposed Ohau Channel outflow diversion is
built.
