following Roads of National Significance (RoNS) projects under the Official Information Act 1982 (the
Act):
• Hope Bypass

Work is currently underway to publish al Roads of National Significance (RoNS) investment cases on
the NZ Transport Agency Waka Kotahi (NZTA) website.
As you are aware, high-level summaries have already been published fol owing the Minister of
Transport’s announcement on 20 October 2025. Detailed investment cases presented to the NZTA
Board for endorsement wil be published by the end of November 2025. Full investment cases and
appendices wil follow in due course, with redactions applied under the Act as appropriate.
