On 20 August 2025, we provided our submission to the Commerce Commission for investment approval, and we received draft approval from the Commission in December 2025.
In the interests of transparency, in March 2026 we asked the Commission to hold off making its final decision so we could provide some additional information following cross submissions. We will continue to review the project and need date regularly, and keep stakeholders across this work. You can read our addendum here.
