We’ve got 11,500 great reasons to make a connection. 
You’re one of them.

We’re building a new $43m electricity connection to the National Grid to keep South Waikato businesses and homes – like yours – reliably powered now and in the future.

Your connection will provide a new supply line for the 11,500 customers in the region who currently rely on a single transmission line at Karāpiro for their electricity supply.

It also means there’ll be enough supply to meet demand as the region continues to grow.


…and more

This project is just one part of a $70m investment in South Waikato to ensure we’re powering your region now and in the future. Here’s what else we’ve been working on from Matamata to Tokoroa:


  • New underground cable linking Matamata’s two substations.
  • Upgrade Tower Road and Lake Road Substations.
  • Upgrade the overhead line between Tower Road and Hinuera Substations.


  • Build a new underground cable to improve reliability of supply.


  • Build a new underground cable between Putāruru and Tirau Substations.
  • New transformer.


  • New underground cables for Domain, Overdale and Horahora Roads.
  • Substation upgrade.


  • Replaced end-of-life underground cable.
  • Substation upgrade.

Construction is underway

You’ll see us, and our contractors working from the Powerco Substation on Arapuni Road just outside Putāruru, through to the bottom of Powerhouse Road in Arapuni.

You may have already seen us setting up the site office and getting things ready.

Construction goes from January 2022 to March 2023.

We’re mainly building in road reserve, and on farmland in some places.

That means traffic management will be in place as needed – please take care and be patient.

COVID-19 protocols are in place

  • COVID-19 protocols are in place onsite to protect our crew and our customers. That means crews will be:
  • Working in bubbles
  • Keeping a 2m distance from the public and other work bubbles
  • Scanning into work sites using the Government COVID tracer app
  • Wearing a mask where safe to do so

We’re pretty chuffed about the new connection and we’ve been talking about it for a while. You can find out more detail, including how we’ve been working with the community to confirm the route past Pokaiwhenua Stream and Duxfield Reserve.
