Answer

I am advised that NZTA has not carried out an analysis of the economic impact of the Waioweka Gorge closure since January 2026, however the SH2 Waioweka Gorge Corridor Resilience Single Stage Business Case, completed in May 2024, estimated economic losses of around $8 million per day during closures.
