Appendix B to this Report summarises the key project-related documents taken into consideration during the course of the IR and the preparation of this Report. The scope of these documents covered:
• Waka Kotahi Board papers and minutes;
• Project Team meeting papers and minutes;
• Waka Kotahi internal memorandums;
• Expert advice provided by the Crown's advisers;
• Cabinet submissions and decision;
• Cabinet briefing papers;
• Ministerial briefing papers; and
• New Zealand Government policy papers and guidelines relevant to the TGP.
As a general principle, our approach to document discovery was to rely mainly on the provision of documents by Waka Kotahi as appropriate custodian of the relevant project records/documents.
The following information and confidentiality protocols were established to manage the collection and use of Review Evidence, and use of relevant information in this Report:
• Confidentiality agreements were signed by review persons before accessing review documents;
• A secure document directory was established between NineSquared and Te Waihanga to store all supplied review documents and detailed summaries of the review documents;
• Recognising that some Waka Kotahi Board papers are confidential and legally privileged, legal advice and extracts of legal advice will not be published or summarised;
• For Gateway Review reports provided for review, copies of these reports have only been provided to Reviewers and other agreed persons. Specific extracts from the reviews have not been included in this Report to respect the confidentiality and independence-principles of a Gateway Review; and
• In keeping with accepted Gateway Review Principles, no specific attribution has been made in this Report to any of the interviewees unless consent was given.
Also, given the commercial-in-confidence nature of project costings to Waka Kotahi's business, we have presented only changes in cost lines.
