Trust and Transparency
The management tool programme is building a digital ecosystem of data, tools and services designed to deliver on core planning and management decision-making requirements of the NDC, targeted rate investment and catchment remediation.
To ensure the principle of “trust and transparency” is practised by the programme, development and outputs are regularly reviewed, internally and externally by leading national and international experts.
This page shares the resources developed by the programme from outputs, including the findings of the peer review committee on core modelling.
Management Tool partners and supporters involved in modelling programme.
Peer Review Committee
Core modelling is subject to independent peer review, to identify limitations and recommendations for continuous improvement (accounting framework).
All supporting modelling is available to the peer review committee but subject to external (contractor) and internal (Healthy Waters) review prior to publication.
The FWMT Stage 1 peer review committee includes:
*
Replaces Nic Conland from “baseline” core modelling review committee (Nic Conland is now an independent project manager for Tātaki Wai – the Kaipara Moana Remediation programme’s variant of the FWMT for Kaipara Uri, AC and NRC).
Technical reports
Technical reports document in detail management tool development and application. Technical reports are subject to supporting agency, Auckland Council and independent peer review.
