New Greerton switching station supports Tauranga development
The Greerton 33kV switching station is critical for electricity supply to the Northern Tauranga region. It supplies substations in Omokoroa, Aongatete, Katikati, Kauri Point, the Bethlehem suburb, and Otumoetai.
Should a major asset failure have occured at the station, it would mean major disruption to the network, and ultimately to your power supply.
The outdoor switching station was originally installed in 1974:
- The original 33kV outdoor switchgear was outdated – if it failed, it would be major, and replacement or repair would have been difficult and time-consuming, leading to significant outages in the area
- The existing outdoor yard was exposed to faults from external factors, such as birds, tree branches or possums – any fault on the 33kV circuit would have resulted in a full site outage
- Constructed on steep terrain, the site was at risk of damage after heavy rainfall or storms
Investment of $3.8m to replace our 33kV Greerton switching station with a new indoor 33kV switchboard. The project included:
- Site works, and construction of a new switch room building, replacing the outdoor 33KV switchgear with an indoor switchboard
- New switchgear which is environmentally safe
- Natural disaster proof protection – the new installation was designed to modern seismic standards, and will offer protection against slips.
An enhanced power supply to the Tauranga region – greater flexibility of electricity supply, and modern equipment means the network is more resilient to unplanned outages. This means minimising disruption business and residential communities.
Construct new substation building
Route for new circuit between Arapuni and Putaruru confirmed
Planned power cut during this period

We strive to minimise impact in the design and placement of network infrastructure and we’re still planning and consulting on the route for the new circuit. The circuit will be a mix of overhead lines – which you will see, and underground cable – which you won’t see. You’ll also see a new building at our Putaruru substation, replacing the ageing existing building there.
