Objective CB1 is to provide for an approach to the monitoring of progress towards, and the achievement of, freshwater objectives. To achieve this, Policy CB1 requires regional councils to develop a monitoring plan which:
- Establishes methods for monitoring the extent to which the values identified under Policy CA2 are provided for in a freshwater management unit.
- Identifies sites at which monitoring will be undertaken that are representative for each freshwater management unit; and
- Recognises the importance of long-term trends in monitoring results.
The methods chosen must include at the minimum:
- surveillance monitoring of microbial health risks to people at primary contact sites in accordance with Appendix 5;
- the monitoring of macroinvertebrate communities;
- measures of the health of indigenous flora and fauna;
- information obtained under Policy CB1(a) and Policy CC1; and
- Mātauranga Māori;
Councils must also establish methods, for example action plans, for responding to monitoring that indicates freshwater objectives will not be met and/or values will not be provided for in a freshwater management unit.
The Macroinvertebrate Community Index has some prominence as a monitoring tool. There is a specific policy requirement to establish methods to respond to a Macroinvertebrate Community Index score below 80, or a declining trend. The methods must investigate the causes of declining trends or the Macroinvertebrate Community Index score below 80; seek to halt declining trends; and seek to improve on a Macroinvertebrate Community Index score if it is below 80 (unless caused by naturally occurring processes, pest or unwanted organism, or by infrastructure listed in Appendix 3).
Transparency of outcomes is also to be improved by a policy requiring that information gathered in accordance with monitoring policies is available to the public regularly and in a suitable form.
