Where we are working

Our teams try to keep disturbance to a minimum, but sometimes you will notice work going on in your area. 

This page lists significant upcoming short-term activity and disruption in the Wellington region. (Short-notice maintenance jobs to keep the trains running safely are not usually listed here.)

Naenae

We are building a new substation on Cambridge Terrace just north of Naenae Station, Hutt Valley. During 2026 we will prepare the foundations ready for the new building to go into place later in the year.  

Taita

We are building a new substation on railway land just south of Pomare Station, Hutt Valley. We are trenching alongside the railway line for ducting and cables, with traffic management in place at times as needed. Final construction and demolition of the old building will happen late 2026.

Trentham

Trentham’s new substation will be at the end of Racecourse Road in Upper Hutt. Work to install the foundations are underway with the building due to arrive late 2026.

Tawa

We are building a new substation just north Tawa Station, Kāpiti Line, on railway land between the train tracks and Duncan Street. We recently cleared vegetation around the area and will be installing a concrete pad foundation during 2026. This will be operation from 2028.
