The Technical Leaders Group provides an update on the Healthy Rivers Policy Process, focusing on scenario analysis, attribute levels, and future options for land losses. Experts are utilized for predictive modeling and non-market valuation studies, aiming to align outcomes with Desired Values. The group is actively assessing options against Values and risks, seeking consensus, and anticipating findings in the new year. The process includes setting attribute levels for water quality, engaging in scenario analysis, and evaluating social, economic, cultural, and ecological impacts. TLG's work streams cover groundwater, economic impact modeling, social and cultural impacts, and Maori knowledge networks. The ongoing efforts aim to provide comprehensive analysis and policy recommendations for the sustainable management of rivers.

Healthy Rivers Policy Process • CSG Focus Statement • e.g., safe to swim, take food, provide well being) • Can be ‘alternative’ detail below that CSG outcomes • Assess options against Values & risk • Consensus? • Seek further scenarios? • TLG advises, using: • Guidelines e.g., NOF • Existing information • Experts input • TLG, using experts for: • Predictive modelling • Non-market valuation studies
TLG advises, using: • Guidelines (e.g., NOF) • Existing information • Experts input Setting Attribute Levels Water quality (N, P, Sed., bacteria) consistent with Desired Values • To Date: • Desired Values developed/confirmed by CSG • National Objectives Framework with attribute tables just produced • TLG presented Freshwater Management Unit options at CSG#5 • Next Steps: • Technical experts develop a Draft Waikato Objectives Framework (a ‘WOF’) • TLG presents that at CSG#7 • Subsequent work on gap-filling on an ‘as needs’ basis • TLG uses ‘WOF’ attribute levels in scenario analysis (next slide)
TLG, using experts for: • Predictive modelling • Non-market valuation studies • To Date TLG has: • Reviewed relevance of previous studies • Built understanding of studies already underway, their availability, what they might deliver for Healthy Rivers, and when • Prepared work briefs for initial technical experts’ workshops (see next slide) • Next Steps: • September – experts report to TLG identifying gaps, work-streams to fill them, costs, and timing. • October - TLG reviews reports, sets priorities on work-streams, develops work briefs, and recommends commissioning to Te RoopuHautu • TLG updates at CSG#7 Scenario Analysis – looking at future options for Limits on point and non-point losses from land Integrated assessment across Values to provide CSG with social, economic, cultural & ecological analysis
TLG, using experts for: • Predictive modelling • Non-market valuation studies • Work-streams currently underway: • Groundwater - hydrology, age, quality, and N attenuation • Extension of the economic impact scenario modelling • Social and cultural impacts of scenarios • Work-brief currently being worked on: • MataurangaMāori knowledge networks and the four contaminants Scenario Analysis – looking at future options for Limits on point and non-point losses from land Integrated assessment across Values to provide CSG with social, economic, cultural & ecological analysis
Beyond CSG 7 Scenario modelling that describes effects of (different) attribute limits on: • Values met • Mitigations required • Costs ($, where, who) • Impacts (social and cultural) Anticipate findings in the new year; then iteration
