New Auckland rail line to benefit freight and passengers
18 Sep 2025
The new Third Main Line in Auckland will be a game changer for rail freight and will enable more frequent passenger trains, Rail Minister Winston Peters and Transport Minister Chris Bishop say.
The Third Main was opened by the Ministers at an event in South Auckland this morning, followed by a passenger train trip down the 6.5km line from Wiri to Middlemore Station.
“We funded this $328 million project in 2020, adding a third track in the busiest part of Auckland’s rail network to ensure a busier passenger network does not derail our economy by blocking rail freight,” Mr Peters says.
