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.)

From Sunday 19 to Thursday 23 July, KiwiRail will working on the railway line during the night in various locations between Redwood Station in Tawa, and just north of Porirua.    

The team will be ‘lifting and packing’, which means using small tools to lift the railway lines, packing fresh ballast underneath (stony material that sits under the tracks), and compressing the area back down to make it solid and strong. 

This is part of our ongoing maintenance to keep the Wellington Metro in good working order.  You can expect to see a truck and small crew at work during this time.  Our people are mindful they’ll be working in the wee small hours when most of us are sleeping and will be careful to keep the noise down.  If you have any questions, you can reach us at contactus@kiwirail.co.nz    

During July through to August 2026 parking at Masterton Station will be more limited than usual while KiwiRail carries out trenching work.  We will be working in sections, so it will only affect a few car parks at a time.  This as part of the work to install a new signalling system for the Wairarapa Line.  

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.
