Network Spend


It’s undoubtedly a horticulture hub, but kiwifruit and avocados are just part of the story in this rapidly growing region. Our network covers the western Bay of Plenty from near Athenree, along the coast east of Te Puke and on to Pongakawa. Port of Tauranga and increasing commercial and residential development mean this part of our network carries a heavy industrial load.

Powerco’s investment priorities are to accommodate Tauranga’s rapid urban growth, maintain safe and reliable power to the port, and supply new businesses. This year, our projects focused on ensuring our network can keep pace and meet the increasing demand for power supply in the Bay.

The region’s ‘SmartGrowth’ strategy identified south-east Papamoa as a key area for subdivision expansion. We recognised the need to future-proof our network for this planned urban development, to assure our customers of reliable power supply to their new homes.

Our team installed new switchgear and circuits from the Te Matai grid exit point near Te Puke and constructed a new substation at Wairakei Avenue in Papamoa East. This infrastructure provides flexibility of power supply to the wider area.

To support central Tauranga’s development, we replaced the crucial Greerton outdoor switching station with a modern indoor switchboard. This has created a more reliable, resilient power supply for our customers in the northern part of town.
