Community Information Day - Upgrading the Cook Strait cable

Transpower are hosting community information days in Makara and Picton about the work we’re doing in the coming years to upgrade Aotearoa’s electricity link between the North and South Islands. This session will be held in Makara.
New Zealand’s High Voltage Direct Current (HVDC) Link has been in service since 1965. It helps keep our electricity system reliable and stable and allows Kiwis to access the lowest-cost electricity across both islands. It’s a critical piece of our national grid. The current HVDC cables were installed in 1991 and have an expected 40-year lifespan, so they need to be replaced by the early 2030s.
As well as replacing the three existing cables and adding a fourth cable, Transpower’s planned renewal programme includes building new cable termination stations at Oteranga Bay and Ōraumoa/Fighting Bay. This work is expected to start in the summer of 2027/2028.
Construction is still some time away, but we want to share our plans with communities near our sites and hear from them about how we can best understand and manage possible impacts.
Come along to Makara Community Hall on Sunday May 3, 10am-2pm.
Grab a coffee and cookie and meet some of the Transpower team
Learn more about the thinking and planning behind the HVDC Link renewal work
Quiz us on HVDC history (our specialist topic!)
Learn how we will update you on our plans
Bring your questions, feedback and any concerns

We’d love to hear from as many local voices as we can. Please share widely with whānau, friends and local organisations.
