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.
  • In the 12 months to November 2021, on average the river provided 152,777 million litres of water to the region each day.
  • The completion of the Waikato 50 treatment plant takes our peak production from the Waikato River to 225 million litres a day. A new pump station in Papakura has been built to enable the pipeline to deliver that amount to Auckland, via the Redoubt Rd storage reservoirs. Read more here.
