2. Technical Leaders Group Update 16th September 2014

3. “You don’t need a roadmap when you lay your own road”

4. Healthy Rivers Policy Process
Desired Values
Setting Attribute Levels
Water quality (N, P, Sed., bacteria) consistent with Desired Values
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
deliberations
CSG
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

5. To Date: Next Steps: Desired Values developed/confirmed by CSG
Setting Attribute Levels
Water quality (N, P, Sed., bacteria) consistent with Desired Values
TLG advises, using:
Guidelines (e.g., NOF)
Existing information
Experts input
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)

6. To Date TLG has: Next Steps: Reviewed relevance of previous studies
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
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 Roopu Hautu
TLG updates at CSG#7

7. Work-streams currently underway:
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:
Matauranga Māori knowledge networks and the four contaminants

8. 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
