Waikato River water

The Waikato River is the longest in New Zealand, running 425 kilometres from Mt Ruapehu to the Tasman Sea at Port Waikato.

Supplying water to Auckland

  • Since 2002, the Waikato River has been part of Auckland’s water supply network, providing an average of 139,000 cubic metres of water to the region each day.
  • Over the past 12 months (to 30 June 2020), water from the Waikato accounted for up to 30% of Auckland's total water supply.
  • We currently have resource consent to take up to 175,000 cubic metres per day from the river.
